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.

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.

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.

Penn Bioengineering Senior Design Expo Featured in Technical.ly Philly

Members of Team Sonura: Tifara Boyce, Gabriela Cano, Gabriella Daltoso, Sophie Ishiwari, & Caroline Magro (credit: Penn BE Labs)

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 2021 iGEM Team Takes Home Multiple Prizes

Four of Penn’s 2021 iGEM team (left to right): Juliette Hooper, Grace Qian, Saachi Datta, and Gloria Lee.

The University of Pennsylvania’s 2021 iGEM team has been awarded several distinctions in this year’s highly competitive iGEM Competition. The International Genetically Engineered Machine Competition is the largest synthetic biology community and the premiere synthetic biology competition for both university and high school level students from around the world. Each year, hundreds of interdisciplinary teams of students combine molecular biology techniques and engineering concepts to create novel biological systems and compete for prizes and awards through oral presentations and poster sessions.

The Penn team’s project, “OptoReader,” is a combined light-simulation device and plate reader, which makes optogenetic experiments more powerful and accessible. The abstract reads:

“Metabolic engineering has the potential to change the world, and optogenetic tools can make metabolic engineering research easier by providing spatiotemporal control over cells. However, current optogenetic experiments are low-throughput, expensive, and laborious, which makes them inaccessible to many. To tackle this problem, we combined a light-stimulation device with a plate reader, creating our OptoReader. This device allows us to automate ~100 complex optogenetic experiments at the same time. Because it is open source and inexpensive, our device would make optogenetic experiments more efficient and available to all.”

Watch the team’s presentation on OptoReader here.

This year’s Penn team was mentored by Lukasz Bugaj, Assistant Professor in Bioengineering. In addition, the team was supported by Brian Chow, Associate Professor in Bioengineering. Chow has supported previous undergraduate iGEM teams at Penn, and was involved in the creation of the iGEM program during his time as a graduate student at MIT.

OptoReader took home the top prizes in three of the four categories in which it was nominated. These prizes include:

  • Best Foundational Advance (best in track)
  • Best Hardware (best from all undergraduate teams)
  • Best Presentation (best from all undergraduate teams)

They were also awarded a Gold Medal Distinction and were included in the Top 10 Overall (from all undergraduate teams, and the only team from the United States to make the top 10) and Top 10 Websites (from all undergraduate teams).

The awards were announced during iGEM’s online Jamboree Award Ceremony on November 14, 2021 (watch the full award ceremony here).

In addition to the outstanding awards recognition, OptoReader was also selected for an iGEM Impact Grant which awards teams $2,500 to continue development of their projects. This new initiative from the iGEM Foundation was announced earlier this year, and with the support of the Frederick Gardner Cottrell Foundation, is distributing a total of $225,000 in grant funds to 90 iGEM teams during the 2021 competition season. Learn more about the Impact Grant and read the full list of winning teams here.

Penn’s 2021 iGEM team was made up of an interdisciplinary group of women undergraduates from the School of Engineering and Applied Science (SEAS) and the School of Arts and Sciences (SAS):

  • Saachi Datta (B.A. in Biology and Religious Studies 2021)
  • Juliette Hooper (B.S.E. and M.S.E. in Bioengineering 2022)
  • Gabrielle Leavitt (B.S.E. in Bioengineering 2021 and current Master’s student in Bioengineering)
  • Gloria Lee (B.A. in Physics and B.S.E. in Bioengineering 2023)
  • Grace Qian (B.S.E. in Bioengineering 2023)
  • Lana Salloum (B.A. in Neuroscience 2022)

They were mentored by three doctoral students in Bioengineering: Will Benman (Bugaj Lab), David Gonzalez Martinez (Bugaj Lab), Gabrielle Ho (Chow Lab). Saurabh Malani, a graduate student in the Avalos Lab at Prince University, was also very involved in mentoring the team.

OptoReader

The graduate mentors were instrumental in quickly bringing the undergraduates up to speed on a diverse array of skills needed to accomplish this project including circuit design, optics, optogenetics, programming, and additive manufacturing. They then coached the team through building and testing prototypes, as well as accomplishing other objectives required for success at iGEM. These other objectives included establishing collaborations with other iGEM teams, performing outreach, and effectively communicating their project through a website and online presentations.

“This team and their work is outstanding,” said William Benman. “Not only did they sweep several awards, but they did it all with a small team and while working with technology they had no prior experience with. They created a device that not only increases accessibility to optogenetics but also allows optogenetic systems to interface directly with computer programs, allowing for completely new research avenues within the field. They are truly a remarkable group.”

Due to the COVID pandemic, the team operated virtually through the summer of 2020, and then continued in person in the summer of 2021 as the project progressed and more students returned to Penn’s campus. Upon return to campus, the work was conducted in both the Bugaj lab in the Stephenson Foundation Educational Laboratory & Bio-MakerSpace, the primary teaching laboratory in Penn Bioengineering and an interdisciplinary makerspace open to anyone at Penn. The team also collaborated with the Avalos Lab at Princeton University, which conducts research in the application of optogenetics to optimize production of valuable  chemicals in microbes.

“I’m beyond excited about this phenomenal showing from team Penn at the iGEM Jamboree awards ceremony,” said faculty mentor Lukasz Bugaj. “This is truly outstanding recognition for what the team has accomplished, and it wouldn’t have happened without essential contributions from everyone on the team.”

Brian Chow added that this achievement is “no small feat,” especially for a hardware project. “The iGEM competition leans toward genetic strain engineering, but the advances in the field made by these incredible students were undeniable,” he said.

Going forward, the team plans to publish a scientific article and file a patent application describing their device. “It’s clear that there is excitement in the scientific community for what our students created, and we’re excited to share the details and designs of their work,” said Bugaj.

Congratulations to all the team members and mentors of OptoReader on this incredible achievement! Check out the OptoReader project website and Instagram to learn more about their project.

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).

Becoming a Bioengineer, Both at Home and On Campus

by Erica K. Brockmeier

The junior year BE-MAD lab series includes modules on dialysis, drug delivery, insect limb control, microfluidics, cell-cell communication, ECG analysis (pictured here), and spectroscopy. (Image: Bioengineering Educational Lab)

While the majority of courses remained online this spring, a small number of lab-based undergraduate courses were able to resume limited in-person instruction. One course was BE 310, the second semester of the Bioengineering Modeling, Analysis, and Design lab sequence. Better known as BE-MAD, this junior-year bioengineering course was able to bring students back to the teaching lab safely this spring while adapting its curriculum to keep remote learners engaged with hands-on lab modules at home.

An Essential Step Towards Becoming a Bioengineer

After learning the basics of chemistry, physics, biology, and math during freshman year and studying bioengineering fundamentals throughout sophomore year, BE-MAD is designed to provide essential hands-on experience to bioengineering majors during their junior years. In BE-MAD, students integrate what they’ve learned so far in the classroom to addressing complex, real-world problems by breaking down the silos that exist across different STEM fields.

“Usually what we hear from students is that this BE 309/310 sequence is when they really feel like they are engineers,” says Brian Chow, one of the BE 310 instructors. “They can put what they learn in classes to work in some practical setting and applied context.”

BE-MAD is also an important course to prepare students for senior design and is designed to be a “safe space to fail,” allowing students to build confidence through trial and error within a supportive environment, explains Sevile G. Mannickarottu, director of the educational laboratories. “We’re trying to build skills needed for senior year as well as teaching students how to think critically about problems by pulling together the materials they’ve learned all in one place,” he says. “By senior year, we want them to, when presented with a problem, not be afraid.”

Adapting BE-MAD for Both Remote and Hybrid Instruction

Traditionally, the BE-MAD lab is taught in the George H. Stephenson Foundation Educational Laboratory & Bio-MakerSpace, the primary bioengineering teaching lab, and includes modules on dialysis, drug delivery, insect limb control, microfluidics, cell-cell communication, ECG analysis, and spectroscopy. In the fall, the first lab in the series (BE-309) pivoted to remote learning using video tutorials of lab experiments and providing real data to students for analysis.

This spring, with more aspects of on-campus life able to reopen, the Educational Laboratory staff and BE-MAD instructors developed protocols in collaboration with David Meaney, Penn Engineering senior associate dean and an instructor for BE 309, and Penn’s Environmental Health and Radiation Safety office to safely reopen the teaching lab and Bio-MakerSpace for both BE-310 and for bioengineering senior design students.

The BE-MAD lab was also recreated on Gather.Town, an online video chat platform where students can speak with group members or instructors. Student groups also had their own tables where they could meet virtually to work on data analysis and lab report writing.

To continue to meet the needs of remote students, BE 310 instructor Lukasz Bugaj says that the curriculum was adapted to be two parallel courses—one that could be done entirely at home and the other in-person. The challenge was to adjust the content so that it could be completed either in-person or virtually, and could be switched from in-person to virtual at a moment’s notice because of COVID precautions, all while maximizing the hands-on experience, says Bugaj. “That’s a real credit to the lab staff of Sevile and Michael Patterson, who put a lot of work into revamping this entire class.”
