2024 Penn Bioengineering Senior Design Projects Advance to Interdepartmental Competition

On April 17, 2024, the Department of Bioengineering held its annual Bioengineering (BE) Senior Design Presentations in the Singh Center for Nanotechnology, followed by a Design Expo in the George H. Stephenson Foundation Educational Laboratory & Bio-MakerSpace.

A panel of expert and alumni judges chose 3 teams to advance to the School-wide, interdepartmental competition, to be held on May 3, 2024.

Team ADONA: Jude Barakat, Allison Elliott, Daniel Ghaderi, Aditi Ghalsasi, Taehwan Kim

ADONA (A Device for the Assisted Detection of Neonatal Asphyxia)

Hypoxic-ischemic encephalopathy (HIE) is a condition that arises from inadequate oxygen delivery or blood flow to the brain around the time of birth, resulting in long-term neurological damage. This birth complication is responsible for up to 23% of neonatal deaths worldwide. While effective treatments exist, current diagnostic methods require specialized neurologists to analyze an infant’s electroencephalography (EEG) signal, requiring significant time and labor. In areas where such resources and specialized training are even scarcer, the challenges are even more pronounced, leading to delayed or lack of treatment, and poorer patient outcomes. The Assisted Detection of Neonatal Asphyxia (ADONA) device is a non-invasive screening tool that streamlines the detection of HIE. ADONA is an EEG helmet that collects, wirelessly transmits, and automatically classifies EEG data using a proprietary machine learning algorithm in under two minutes. Our device is low-cost, automated, user-friendly, and maintains the accuracy and reliability of a trained neurologist. Our classification algorithm was trained using 1100 hours of annotated clinical data and achieved >85% specificity and >90% sensitivity on an independent 200 hour dataset. Our device is now produced in Agilus 30, a flexible and tear resistant material, that reduces form factor and ensures regulatory compliance. For our final prototype, we hope to improve electrode contact and integrate software with clinical requirements. Our hope is that ADONA will turn the promise of a safer birth into a reality, ensuring instant peace of mind and equitable access to healthcare, for every child and their families.

Team Epilog: Rohan Chhaya, Carly Flynn, Elena Grajales, Priya Shah, Dori Xu

Epilog

To address the critical need for effective, at-home seizure monitoring in pediatric neurology, particularly for Status Epilepticus (SE), our team developed Epilog: a rapid-application electroencephalography (EEG) headband. SE is a medical emergency characterized by prolonged or successive seizures and often presents with symptoms too subtle to notice or easily misinterpreted as post-convulsive fatigue. This leads to delayed treatment and increased risks of neurological damage and high mortality. Current seizure detection technologies are primarily based on motion or full-head EEG, rendering them ineffective at detecting SE and impractical for at-home use in emergency scenarios, respectively. Our device is designed to be applied rapidly during the comedown of a convulsive seizure, collect EEG data, and feed it into our custom machine learning algorithm. The algorithm processes this data in real-time and alerts caregivers if the child remains in SE, thereby facilitating immediate medical decision-making. Currently, Epilog maintains a specificity of 0.88 and sensitivity of 0.95, delivering decisions within 15 seconds post-seizure. We have demonstrated clean EEG signal acquisition from eight standard electrode placements and bluetooth data transmission from eight channels with minimal delay. Our headband incorporates all necessary electrodes and adjustable positioning of the electrodes for different head sizes. Our unique gel case facilitates rapid electrode gelation in less than 10 seconds. Our most immediate goals are validating our fully integrated device and improving features that allow for robust, long-term use of Epilog. Epilog promises not just data, but peace of mind, and empowering caregivers to make informed life-saving decisions.

Team NG-LOOP: Katherine Han, Jeffrey Huang, Dahin Song, Stephanie Yoon

NG-LOOP

Nasogastric (NG) tube dislodgement occurs when the feeding tube tip becomes significantly displaced from its intended position in the stomach, causing fatal consequences such as aspiration pneumonia. Compared to the 50% dislodgement rate in the general patient population, infant patients are particularly affected ( >60%) due to their miniature anatomy and tendency to unknowingly tug on uncomfortable tubes. Our solution, the Nasogastric Lightweight Observation and Oversight Product (NG-LOOP) provides comprehensive protection from NG tube dislodgement. Physical stabilization is combined with sensor feedback to detect and manage downstream complications of tube dislodgement. The lightweight external bridle, printed with biocompatible Accura 25 and coated with hydrocolloid dressing for comfort and grip, can prevent dislodgement 100% of the time given a tonic force of 200g. The sensor feedback system uses a DRV5055 linear hall effect sensor with a preset difference threshold, coupled with an SMS alert and smart plug inactivation of the feeding pump. A sensitivity of 90% and specificity of 100% in dislodgement detection was achieved under various conditions, with all feedback mechanisms being initiated in response to 100% of threshold triggers. Future steps involve integration with hospital-grade feeding pumps, improving the user interface, and incorporating more sizes for diverse age inclusivity.

Illuminating the Unseen: Former Penn iGEM Team Publishes Award-Winning Optogenetic Device

Diagram of the optoPlateReader, a high-throughput, feedback-enabled optogenetics and spectroscopy device initially developed by Penn 2021 iGEM team.

For bioengineers today, light does more than illuminate microscopes. Stimulating cells with light waves, a field known as optogenetics, has opened new doors to understanding the molecular activity within cells, with potential applications in drug discovery and more.

Thanks to recent advances in optogenetic technology, much of which is cheap and open-source, more researchers than ever before can construct arrays capable of running multiple experiments at once, using different wavelengths of light. Computing languages like Python allow researchers to manipulate light sources and precisely control what happens in the many “wells” containing cells in a typical optogenetic experiment.

However, researchers have struggled to simultaneously gather data on all these experiments in real time. Collecting data manually comes with multiple disadvantages: transferring cells to a microscope may expose them to other, non-experimental sources of light. The time it takes to collect the data also makes it difficult to adjust metabolic conditions quickly and precisely in sample cells.

Now, a team of Penn Engineers has published a paper in Communications Biology, an open access journal in the Nature portfolio, outlining the first low-cost solution to this problem. The paper describes the development of optoPlateReader (or oPR), an open-source device that addresses the need for instrumentation to monitor optogenetic experiments in real time. The oPR could make possible features such as automated reading, writing and feedback in microwell plates for optogenetic experiments.

Left to right: Will Benman, Gloria Lee, Saachi Datta, Juliette Hooper, Grace Qian, David Gonzalez-Martinez, and Lukasz Bugaj (with Max).

The paper follows up on the award-winning work of six University of Pennsylvania alumni — Saachi Datta, M.D. Candidate at Stanford School of Medicine; Juliette Hooper, Programmer Analyst in Penn’s Perelman School of Medicine; Gabrielle Leavitt, M.D. Candidate at Temple University; Gloria Lee, graduate student at Oxford University; Grace Qian, Drug Excipient and Residual Analysis Research Co-op at GSK; and Lana Salloum, M.D. Candidate at Albert Einstein College of Medicine — who claimed multiple prizes at the 2021 International Genetically Engineered Machine Competition (iGEM) as Penn undergraduates.

The International Genetically Engineered Machine Competition (or iGEM) is the largest synthetic biology community and the premiere synthetic biology competition for both university and high school students from around the world. Hundreds of interdisciplinary teams of students compete annually, combining molecular biology techniques and engineering concepts to create novel biological systems and compete for prizes and awards through oral presentations and poster sessions.

The optoPlateReader was initially developed by Penn’s 2021 iGEM team, combining a light-stimulation device with a plate reader. At the iGEM competition, the invention took home Best Foundational Advance (best in track), Best Hardware (best from all undergraduate teams), and Best Presentation (best from all undergraduate teams), as well as a Gold Medal Distinction and inclusion in the Top 10 Overall and Top 10 Websites lists. (Read more about the 2021 iGEM team on the BE Blog.)

The original iGEM project focused on the design, construction, and testing of the hardware and software that make up the oPR, the focus of the new paper. After iGEM concluded, the team showed that the oPR could be used with real biological samples, such as cultures of bacteria. This work demonstrated that the oPR could be applied to real research questions, a necessary precursor to publication, and that the device could simultaneously monitor and manipulate living samples. 

The main application for the oPR is in metabolic production (such as the creation of pharmaceuticals and bio-fuels). The oPR is able to issue commands to cells via light but can also take live readings about their current state. In the oPR, certain colors of light cause cells to carry out different tasks, and optical measurements give information on growth rates and protein production rates.

In this way, the new device is able to support production processes that can adapt in real time to what cells need, altering their behavior to maximize yield. For example, if an experiment produces a product that is toxic to cells, the oPR could instruct those cells to “turn on” only when the population of cells is dense and “turn off” when the concentration of that product becomes toxic and the cellular population needs to recover. This ability to pivot in real time could assist industries that rely on bioproduction.

The main challenges in developing this device were in incorporating the many light emitting diodes (LEDs) and sensors into a tiny space, as well as insulating the sensors from the nearby LEDs to ensure that the measured light came from the sample and not from the instrument itself. The team also had to create software that could coordinate the function of nearly 100 different sets of LEDs and sensors. Going forward, the team hopes to spread the word about the open-source oPR to other researchers studying metabolic production to enable more efficient research.

Lukasz Bugaj, Assistant Professor in Bioengineering and senior author of the paper, served as the team’s mentor along with Brian Chow, formerly an Associate Professor in Bioengineering and a founding member of the iGEM program at MIT, and Jose Avalos, Associate Professor of Chemical and Biological Engineering at Princeton University.

Key to the project’s development was the guidance of Bioengineering graduate students Will Benman, David Gonzalez Martinez, and Gabrielle Ho, as well as that of Saurabh Malani, a graduate student at Princeton University.

Much of the original work was conducted in Penn Bioengineering’s Stephenson Foundation Educational Laboratory & Bio-MakerSpace, with important contributions made by Michael Patterson, Director of Educational Laboratories in Bioengineering, and Sevile Mannickarottu, Director of Technological Innovation and Entrepreneurship in Penn Engineering’s Entrepreneurship Program.

This project was supported by the Department of Bioengineering, the School of Engineering and Applied Science, and the Office of the Vice Provost for Research (OVPR), and by funding from the National Institute of Health (NIH), the National Science Foundation (NSF), and the Department of Energy (DOE).

The iGEM program was created at the Massachusetts Institute of Technology in 2003. Read stories in the BE Blog featuring recent Penn iGEM teams here.

Penn Bioengineering Cockroach Lab Featured in Popular Mechanics

Every Penn Bioengineering semester culminates in a series of “demo days” — dedicated time in which undergraduate Bioengineering students demonstrate projects made in their Bioengineering lab courses or in Senior Design for their classmates and faculty. These are held in the George H. Stephenson Foundation Educational Laboratory & Bio-MakerSpace (or the Penn BE Labs), the dedicated teaching lab for the Bioengineering Department which also functions as an interdisciplinary bio-makerspace open to the entire Penn community.

For the Fall 2023 demos, Popular Mechanics paid a visit to the BE Labs to witness the (in)famous “cockroach lab,” a staple of the third year course “Bioengineering, Modeling, Analysis, and Design Laboratory” (affectionately known as BE MAD). This year’s cockroach demos featured a miniature Taylor Swift — flaunting a cockroach limb — and several projects featuring the faces of course faculty, David Meaney, Solomon R. Pollack Professor in Bioengineering and Senior Associate Dean in Penn Engineering, and Michael Patterson, Director of Educational Laboratories in Bioengineering.

The Art and Science of Living-Like Architecture

by Devorah Fischler

Collaborators from Penn Engineering and the Stuart Weitzman School of Design have created “living-like” bioactive interior architecture designed to one day protect us from hidden airborne threats. The figure above demonstrates (A) design for support lattices for the team’s innovative bioactive sites, (B) a ribbon-like geometry for hanging and (C, D) how these structures may be integrated into indoor environments to biologically sense and react to air.

“This technology is not alive,” says Laia Mogas-Soldevila. “It is living-like.”

The distinction is an important one for the assistant professor at the Stuart Weitzman School of Design, for reasons both scientific and artistic. With a doctorate in biomedical engineering, several degrees in architecture, and a devotion to sustainable design, Mogas-Soldevila brings biology to everyday life, creating materials for a future built halfway between nature and artifice.

The architectural technology she describes is unassuming at first look: A freeze-dried pellet, small enough to get lost in your pocket. But this tiny lump of matter, the result of more than a year’s collaboration between designers, engineers and biologists, is a biomaterial that contains a “living-like” system.

When touched by water, the pellet activates and expresses a glowing protein, its fluorescence demonstrating that life and art can harmonize into a third and very different thing, as ready to please as to protect. Woven into lattices made of flexible natural materials promoting air and moisture flow, the pellets form striking interior design elements that could one day keep us healthy.

“We envision them as sensors,” explains Mogas-Soldevila. “They may detect pathogens, such as bacteria or viruses, or alert people to toxins inside their home. The pellets are designed to interact with air. With development, they could monitor or even clean it.”

For now, they glow, a triumphant first stop on the team’s roadmap to the future. The fluorescence establishes that the lab’s biomaterial manufacturing process is compatible with the leading-edge cell-free engineering that gives the pellets their life-like properties.

A rapidly expanding technology, cell-free protein expression systems allow researchers to manufacture proteins without the use of living cells.

Gabrielle Ho, Ph.D. candidate in the Department of Bioengineering and co-leader of the project, explains how the team’s design work came to be cell-free, a technique rarely explored outside of lab study or medical applications.

“Typically, we’d use living E. coli cells to make a protein,” says Ho. “E. coli is a biological workhorse, accessible and very productive. We’d introduce DNA to the cell to encourage expression of specific proteins. But this traditional method was not an option for this project. You can’t have engineered E. coli hanging on your walls.”

Cell-free systems contain all the components a living cell requires to manufacture protein —energy, enzymes and amino acids — and not much else. These systems are therefore not alive. They do not replicate, and neither can they cause infection. They are “living-like,” designed to take in DNA and push out protein in ways that previously were only possible using living cells.

“One of the nicest things about these materials not being alive,” says Mogas-Soldevila, “is that we don’t need to worry about keeping them that way.”

Unlike living cells, cell-free materials don’t need a wet environment or constant monitoring in a lab. The team’s research has established a process for making these dry pellets that preserves bioactivity throughout manufacturing, storage and use.

Bioactive, expressive and programmable, this technology is designed to capitalize on the unique properties of organic materials.

Mogas-Soldevila, whose lab focuses exclusively on biodegradable architecture, understands the value of biomaterials as both environmentally responsible and aesthetically rich.

“Architects are coming to the realization that conventional materials — concrete, steel, glass, ceramic, etc. — are environmentally damaging and they are becoming more and more interested in alternatives to replace at least some of them. Because we use so much, even being able to replace a small percentage would result in a significant reduction in waste and pollution.”

Her lab’s signature materials — biopolymers made from shrimp shells, wood pulp, sand and soil, silk cocoons, and algae gums — lend qualities over and above their sustainable advantages.

“My obsession is diagnostic, but my passion is playfulness,” says Mogas-Soldevila. “Biomaterials are the only materials that can encapsulate this double function observed in nature.”

This multivalent approach benefited from the help of Penn Engineering’s George H. Stephenson Foundation Educational Laboratory & Bio-MakerSpace, and the support of its director, Sevile Mannickarottu. In addition to contributing essential equipment and research infrastructure to the team, Mannickarottu was instrumental in enabling the interdisciplinary relationships that led the team to success, introducing Ho to the DumoLab Research team collaborators. These include Mogas-Soldevila, Camila Irabien, a Penn Biology major who provided crucial contributions to experimental work, and Fulbright design fellow Vlasta Kubušová, who co-led the project during her time at Penn and who will continue fueling the project’s next steps.

Safe and Sound: Sonura Supports Newborn Development by Sequestering Disruptive Noise

by Nathi Magubane

Recipients of the 2023 President’s Innovation Prize, team Sonura, five bioengineering graduates from the School of Engineering and Applied Science, have created a device that filters out disruptive environmental noises for infants in neonatal intensive care units. Their beanie offers protection and fosters parental connection to newborns while also supporting their development.

Machines beeping and whirring in a rhythmic chorus, the droning hum of medical equipment, and the bustles of busy health care providers are the familiar sounds of an extended stay at a hospital. This cacophony can create a sense of urgency for medical professionals as they move about with focused determination, closely monitoring their patients, but for infants in neonatal intensive care units (NICU) this constant noise can be overwhelming and developmentally detrimental.

Enter Tifara Boyce, from New York City; Gabriela Cano, from Lawrenceville, New Jersey; Gabriella Daltoso, from Boise, Idaho; Sophie Ishiwari, from Chicago, and Caroline Magro, from Alexandria, Virginia, bioengineering graduates from the School of Engineering and Applied Science, who have created the Sonura Beanie. Their device filters out harmful noises for NICU infants while supporting cognitive and socioemotional development by allowing parents to send voice messages to their newborns.

The Sonura team members are recipients of the 2023 President’s Innovation Prize, which includes an award of $100,000 and an additional $50,000 living stipend per team member. The recent graduates will spend the year developing their product.

“The Penn engineers behind Sonura are determined to make a difference in the world,” says President Liz Magill. “They identified a substantial medical challenge that affects many parents and their newborn children. With the guidance of their mentors, they are taking key steps to address it and in doing so are improving the developmental prospects for children in the NICU. I am proud the University is able to support their important work.”

The Sonura Beanie’s creation began in the Stephenson Foundation Educational Laboratory and Bio-MakerSpace as a part of the Bioengineering Senior Design class project.

She was particularly struck by the noisiness of the environment and considered the neurodevelopmental outcomes that may arise following long-term exposure to the harsh sounds at a critical developmental stage for infants. This concern prompted Magro to consult her team about potential solutions.

“I was really eager to tackle this problem because it bears some personal significance to me,” says Cano, who works on the device’s mobile application. “My sister was a NICU baby who was two months premature, so, when Caroline and I started talking about the issues a disruptive environment could cause, it seemed like the pieces of a puzzle started to come together.”

Technical.ly Philly journalist Sarah Huffman recently paid another visit to Penn Bioengineering’s George H. Stephenson Foundation Educational Laboratory & Bio-MakerSpace, this time for the 2023 Senior Design Expo. Following the annual Senior Design presentations held in the Singh Center for Nanotechnology, in which graduating fourth-year undergraduates in Bioengineering presented their final capstone projects, the Expo offered an opportunity for the teams to do live demonstrations (or demos) for the department’s internal competition judges and the wider BE community.

“In the course of the day, students presented the challenge they were aiming to solve and the technical details of their solution. After, demonstrations sought to find if the devices really worked.

‘[It’s] looking at the device as a whole, because quite frankly, you can say whatever you want at a presentation, does it really work,’ said [BE Labs Director Sevile] Mannickarottu. ‘You can make it look pretty, “but does it work?” is the big question.'”

“Creativity needs to let go of control”: Penn BE Labs Featured on the Shifting Schools Podcast

Shifting Schools. Sevile Mannickarottu, @PennBELabs. Thanks to our sponsors: STEM Sports & MackinMaker.
Sevile Mannickarottu, Director of Educational Labs, Penn Bioengineering

Sevile Mannickarottu, Director of Educational Laboratories in the Department of Bioengineering (BE), was interviewed in a recent episode of Shifting Schools, a weekly podcast that hosts educators and thought-leaders in conversations about the latest trends in education and EdTech. Mannickarottu, a Penn Engineering alumnus, runs the George H. Stephenson Foundation Educational Laboratory & Bio-MakerSpace, also known as the Penn BE Labs. In addition to being the primary teaching lab for Penn Bioengineering, the Penn BE Labs has grown into “the world’s only interdisciplinary Bio-MakerSpace.”

Students busy at work in the Penn BE Labs.

MakerSpaces–collaborative, educational work environments–have recently grown in popularity. Penn BE Labs distinguishes itself as a Bio-MakerSpace, embracing the interdisciplinary character of bioengineering by offering itself freely as a space for both academic and personal projects. It is stocked with tools ranging from 3D printers, laser cutters, and electrical equipment, including supplies to support work in molecular biology, physiology, chemistry, and microfluidics.

In the episode, hosts Tricia Friedman and Jeff Utecht talk with Mannickarottu about the organic process by which the Penn BE Labs evolved from a standard teaching space for undergraduate engineering laboratory courses into a student-driven hub of creativity and entrepreneurial spirit that is open to the entire Penn community regardless of discipline or major.

A student using the BE Labs' sewing machine for a project.Mannickarottu and his team have found that “creativity needs to let go of control – that’s when fun things happen.” As the lab staff and faculty started to allow more creative freedom in the undergraduate bioengineers’ education, the requests for more supplies started pouring in and the lab’s activities and resources grew.  “Honestly, we’re driven almost entirely by student requests and student demands,” says Mannickarottu. So when a student requested a sewing machine for a project? They went out and bought one, adding to their ever-growing stockpile of tools. Over time, more and more diverse projects have emerged from the BE Labs, many of them going on to win awards and grow beyond Penn’s campus as independent startups.

In case this sounds out of reach for smaller institutions, Mannickarottu shares words of encouragement. “The biggest thing,” he says, “is to allow for creativity on the part of the students.” A lab or program can start their own MakerSpace surprisingly inexpensively and build their inventory over time. His number one recommendation for those looking to replicate the success of Penn BE Labs is to allow students freedom to innovate, and administrators will be drawn to invest in the MakerSpace to allow for even more opportunities for them to create and thrive.

BE Labs logoTo help others get started, the Penn BE Labs staff have put a wide range of resources online, including extensive video and photo archives, FAQ’s, tutorials, information about student projects and startups, and equipment inventories. A 2019 post written for the BE Blog by BE alumna Sophie Burkholder (BSE ‘20 & MSE ‘21) gives the reader tips on “how to build your own MakerSpace for under $1500.”

Though it may currently be “the world’s only interdisciplinary Bio-MakerSpace,” the greatest legacy of the Penn BE Labs would be to be known as the first of many.

Penn’s Venture Lab Startup Challenge awarded its 2022 prize to a sustainable and cost-effective water-testing startup. The venture, ToxiSense, was awarded at a ceremony on April 29, at Tangen Hall, Penn’s hub for student entrepreneurship and innovation.

Co-founded by four first-year students—Aravind Krishnan, Udit Garg, Andrew Diep-Tran, and Aarush Sahni—ToxiSense aims to improve the endotoxin testing required for drinking water and biopharma products through genetically engineering plants with bioluminescent properties. Biopharmaceutical products and drinking water must be tested for endotoxins, the sickness-causing molecule from bacteria. The current method relies on expensive horseshoe crab blood and is environmentally damaging. ToxiSense genetically engineered the Arabidopsis plant to luminesce based on the endotoxin concentration applied to it, serving as a sustainable, cost-effective solution.

ToxiSense was selected from a field of eight finalist teams—including DeToXyFi, Groov, Impact Local, Miren, Nemu, Ossum Technologies, and Shinkei Systems Corp.—who advanced from 30 ventures during the semi-finals portion of the competition, which consisted of a day of virtual pitching and Q&A in front of alumni entrepreneur and investor panels. For the finals, teams pitched to a panel of alumni judges and in front of a live audience of nearly 200 attendees as they competed for over $150,000 in cash and prizes to launch their startups.

“The Startup Challenge is Venture Lab’s premier yearly event, showcasing Penn’s most promising teams of student entrepreneurs,” says Lori Rosenkopf, vice dean of entrepreneurship and Simon and Midge Palley Professor at the Wharton School. “This year’s finalists included undergraduate and graduate students from across the University, and their products offered solutions for environmental, financial, health, and social challenges. These motivated teams capture the spirit of Penn entrepreneurship—innovative, interdisciplinary, inclusive—and we offer our congratulations and our optimistic wishes for their futures.”
