Strella Biotechnology tackles food waste by ‘hacking the fruit’

Last spring, we congratulated Penn Bioengineering graduating BE senior Malika Shukurova (BSE ’19) and her co-founder Katherine Sizov (Biology ’19) on their President’s Innovation Prize for their start-up Strella Biotechnology. Katherine began the work for what became Strella as a sophomore in the Penn Bioengineering George H. Stephenson Foundation Educational Laboratory & Bio-MakerSpace.

On the second floor of the Pennovation Center, Strella Biotechnology is hard at work turning their student-led startup into a full-fledged company that’s ready to make a major impact in the agricultural sector.

May graduates Katherine Sizov and Malika Shukurova, respectively the CEO and head of R&D at Strella, share a 2019 President’s Innovation Prize, which includes $100,000 of financial support, a $50,000 living stipend for both awardees, and a year of dedicated co-working and lab space at the Pennovation Center. The alumnae and their company are now poised to take on the challenge of $1 trillion worth of food waste.

Strella’s biosensors are designed to give packers real-time data on how ripe their fruits are while being stored between harvesting and selling. Using bio-inspired sensors that measure the ethylene gas produced by fruits as they ripen, Strella successfully “hacked the fruit” to create their patent-pending biosensors. Now, only six months after graduation, Strella has six paying customers and is aiming for $100,000 in sales by the end of the season.

Beyond the work needed to deploy their first paid product, Strella also has a clear view of what needs to be done for future progress of the company. This means running experiments in the lab to refine their current sensors while conducting other experiments that will help the company be able to monitor other types of fresh foods. It’s a job that Shukurova says involves a lot of multitasking and requires an “all-hands” approach to problem solving.

“We set up experiments that run for several days, and during that period we work on different tasks. I prepare for the next set of experiments, Jacob [Jordan] and Katherine travel to our customers to deploy sensors, and Zuyang [Liu]]works on IoT [Internet of Things]. At the end of the day we all come together to discuss results and future plans,” says Shukurova about their company’s work flow.

Rebound Liberia Kicks Into a New Phase

Last spring, we congratulated Penn Bioengineering graduating senior Oladunni Alomaja (BSE ’19) and her partners at Rebound Liberia on their President’s Engagement Prize. Check out the article and video below on their exciting project.

By Brandon Baker

Fueled by the encouragement and support they received this spring and summer, the three Penn alumni behind Rebound Liberia are now laser-focused on carrying their mission of promoting education and empowerment straight to the basket.

The Rebound Liberia team is led by Princess Aghayere, Oladunni Alomaja, and Summer Kollie, all May Penn graduates who received the President’s Engagement Prize — a $100,000 project prize and $50,000 living stipend per team member, awarded for post-graduation projects that make a positive, lasting difference in the world. The trio, each of whom has connections to West Africa and strives to give back, proposed an NGO that would bridge the literacy gap in post-conflict Liberia between male and female youth through workshops and a basketball program for women.

On Sept. 4, after months of preparation, the team relocated to Monrovia, Liberia, and is settling in.

“I think there’s some cultural shock,” says Aghayere, musing about the adjustment. “But Penn is a great place to travel and a lot of us took advantage of opportunities to travel. I’m not surprised, because this is not my first time on the continent, but there are things unique about Liberia. Getting used to the accents, the weather, the currency — but it’s fun.”

Aghayere and Alomaja were born in Nigeria, while Kollie is from Liberia.

Their days so far, they explain, have been consistently jam-packed with meetings. At present, they’re planning an inter-school basketball tournament to introduce their program to Liberia; in recent weeks, they’ve made connections with school administrators, found their footing in the community, and worked through the logistics of organizing a tournament — which, they note, they had some practice with in 2018, creating a summer basketball clinic in Monrovia, Liberia, for girls that was hosted twice a week.

The upcoming tournament, which will include 120 female players on Nov. 22–24, represents a first step toward their larger intention to build a basketball court and program, and marry that with literacy resources. They aim to serve approximately 60 girls in their program.

“We didn’t think it would be wise to move in September and not have an event until the next June or so, so we thought [of] the tournament,” says Aghayere, explaining the origins of the tournament. “At first, we were thinking we’d have a team and foster the game amongst girls here in Monrovia, and we wanted to include a lot more girls and create this sort of league of our own while introducing ourselves as this new social enterprise in Liberia. We thought a tournament would be a launch of Rebound Liberia and introduce us to the community here.”

BE Senior Design Team Wins Berkman Prize

Senior Design Group MeVR

We would like to congratulate Penn Bioengineering Senior Design team MeVR on winning a Berkman Prize. MeVR consists of current BE seniors Nicole Chiou, Gabriel DeSantis, Ben Habermeyer, and Vera Lee. Awarded by the Penn Engineering Entrepreneurship Program, the Berkman Opportunity Fund provides grants to support students with innovative ideas that might turn into products and companies.

Bioengineering Seniors Ben Habermeyer (top left), Nicole Chiou (top right), Gabriel DeSantis (bottom right), and Vera Lee (bottom left)

MeVR is a bioresponsive virtual reality platform for administering biofeedback therapy. Biofeedback is the process of gaining greater awareness of involuntary physiological functions using sensors that provide information on the activity of those bodily systems, with the goal of gaining voluntary control over functions such as heart rate, muscle tension, and pain perception. This therapy is used to treat a variety of conditions such as chronic pain, stress, anxiety, and PTSD. These treatments cost on the order of hundreds to thousands of dollars, require the presence of a therapist to set up and deliver the therapy session, and are generally not interactive or immersive. MeVR is a platform to reduce these limitations of biofeedback therapy through an individualized, immersive, and portable device which guides users through biofeedback therapy using wearable sensors and a virtual reality environment which responds in real-time to biological feedback from the user’s body.

As part of the two-semester Senior Design course (BE 495 & BE 496), MeVR and the rest of the Bioengineering B.S.E. seniors will continue to develop their projects throughout the remainder of the academic year in George H. Stephenson Foundation Educational Laboratory & Bio-MakerSpace, culminating in their final presentations and the annual SEAS Senior Design Project Competition at the end of the spring 2020 semester.

 

Students’ Innovative Orthotic Device Wins Rothberg Catalyzer

NB: Penn Bioengineering would like to congratulate one of its current Senior Design teams (Alec Bayliff, Bram Bruno, Justin Swirbul, and Vishal Then) which took home the $500 Pioneer Award at this year’s Rothberg Catalyzer competition this past weekend! Keep reading for more information on the competition, awards, and winners.

Penn Health-Tech’s Rothberg Catalyzer is a two-day makerthon that challenges interdisciplinary student teams to prototype and pitch medical devices that aim to address an unmet clinical need.

The Catalyzer’s third competition was held last weekend and was won by MAR Designs, a team of Mechanical Engineering and Applied Mechanics graduate students: Rebecca Li, Ariella Mansfield and Michael Sobrepera.

MAR Designs took home the top prize of $10,000 for their project, an orthotic device that children with cerebral palsy can more comfortably wear as they sleep.

According to the team’s presentation, existing wrist orthoses “improve function and treat/prevent spasticity. However, patients report that these devices are uncomfortable which leads to lack of compliance and may also prevent patient’s eligibility for surgeries.” MAR Designs’ device initially allows full range of motion, but gradually straightens the wrist as the child is falling asleep.

In second place was Splash Throne. Team members Greg Chen, Nik Evitt, Jake Crawford and Meghan Lockwood proposed a toilet safety frame intended for elderly users. Embedded sensors track basic health information, like weight and heart-rate, as part of a preventative health routine.

Integrated Product Design students Jonah Arheim, Laura Ceccacci, Julia Lin and Alex Wan took third place with ONESCOPE, an untethered, hands-free laproscope designed to make minimally-invasive surgeries faster and safer.

Finally, SchistoSpot took home the Catalyzer’s Pioneer Award. Bioengineering and Computer and Information Science seniors Alec Bayliff, Bram Bruno, Justin Swirbul and Vishal Then designed a low-cost microscopy system that can aid in the diagnosis of the parasitic disease schistosomiasis by detecting eggs in urine samples, eliminating the need for a hospital visit.

The event was made possible by a three-year donation by scientist and entrepreneur Jonathan Rothberg, with the intent of inspiring the next generation of healthcare innovators.

Chip Diagnostics receives the JPOD @ Philadelphia QuickFire Challenge Award

By Erica K. Brockmeier

Chip Diagnostics is the awardee of the JPOD @ Philadelphia QuickFire Challenge sponsored by Johnson & Johnson Innovation — JLABS. The Challenge was designed to accelerate healthcare innovation and commercialization within the greater Philadelphia area.

Chip Diagnostics is a Philadelphia-based device company founded in 2016 based on research from the lab of David Issadore, Assistant Professor of Bioengineering and Electrical and Systems Engineering in the School of Engineering and Applied Science. The startup combines microelectronics, microfluidics, and nanomaterials with the aim to better diagnose cancer. The company is developing technologies and digital assays for minimally-invasive early cancer detection and screening that can be done using mobile devices.

There has been a long interest in diagnosing cancer using blood tests by looking for proteins, cells, or DNA molecules shed by tumors, but these tests have not worked well for many cancers since the molecules shed tend to be either nonspecific or very rare.

Issadore’s group aims to target different particles called exosomes: Tiny particles shed by cells that contain similar proteins and RNA as the parent cancer cell. The problem, explains Issadore, is that because of the small size of the exosomes, conventional methods such as microscopy and flow cytometry wouldn’t work. “As an engineering lab, we saw an opportunity to build devices on a nanoscale that could specifically sort the cancer exosomes versus the background exosomes of other cells,” he explains.

After Issadore was approached by the IP group at PCI Ventures in the early stages of their research, Chip Diagnostics has since made huge strides as a company. Now, as the awardee of the JPOD @ Philadelphia QuickFire Challenge, Chip Diagnostics will receive $30,000 in grant funding to further develop the first-in-class, ultra-high-definition exosomal-based cancer diagnostic. The award also includes one year of residency at Pennovation Works as well as access to educational programs and mentoring provided by Johnson & Johnson Family of Companies global network of experts.

Building Literacy and Leadership Through Basketball

by Gwyneth K. Shaw

Bioengineering student Oladunni Alomaja, who goes by the nickname Ola, moved to the United States six years ago.

Princess Aghayere, Summer Kollie, and Oladunni Alomaja met for the first time before they even started college, at Penn’s Pre-Freshman Program. Drawn together by their common ties to West Africa, they became fast friends and, eventually, roommates. Kollie is originally from Liberia, and Aghayere and Alomaja were born in Nigeria.

Although all three moved to the United States as children or teenagers, each felt compelled to give back to Africa. As winners of one of the 2019 President’s Engagement Prizes (PEP), they will.

Their project, Rebound Liberia, aims to give young women a platform to develop their voices and, ultimately, to position them to create a new, more positive narrative about the country. It involves building a basketball court in Monrovia, the capital, and pairing it with literacy programs and a resource center.

The initial goal is to serve about 60 girls between the ages of 8 and 18, to complement what the young women are learning in school, and to build on those skills during the summer break. The PEP gives their project a $100,000 award, as well as a $50,000 living stiped for each of them.

All three women said the ability to begin their post-Penn lives giving back is hugely significant.

“We have always had that passion, that drive to want to work with youth in West Africa, to give back and just kind of help the youth in the way we have been helped along the way of our journey,” Kollie says.

“In Africa, West Africa especially, it’s very patriarchal,” says Alomaja, who goes by the nickname Ola. “We’re giving girls a voice. We’re empowering them, teaching them leadership skills. And we’re teaching them so many things that their society might have taken away from them or has not given them the opportunity to learn.

“For me, being involved in this project means I will be able to see that through and to have a close, interactive relationship with these girls for a long time, to help reach their own goals. I want to help them realize they’re more than what their society tells them they can be.”

Aghayere, a standout forward on Penn’s women’s basketball team, began playing basketball not long after she and her family moved to Virginia when she was 8. She’s driven by research showing the power of sports to teach leadership, and she can’t wait to expand the sport’s reach in Liberia.

“Basketball is definitely on the rise in Liberia. If we can build this program to a world-class program and really sort of help redefine Liberia in a new way, it will help. We’ve talked a lot about the negative narratives about Liberia,” Aghayere says. “We want to see this not only be self-sustainable but be something that people from all across West Africa come to and know Liberia for.”

The genesis of the project lies in Penn Engineering’s global and local-service program. Aghayere and Kollie had both been involved in summer projects in Africa and in 2018 won a grant from the Davis Projects for Peace Program.

Their project, Promoting Education and Cultivating Empowerment (PEACE) through Girls Basketball, renovated a basketball court in Monrovia and hosted a basketball clinic for girls twice a week. Each participant received a jersey, shoes, and a basketball, all donated by the Penn women’s basketball team.

Kollie and Aghayere also put together weekly workshops for the girls, discussing everything from sexual and reproductive health to goal-setting. They took the girls to Monrovia’s Coca-Cola plant and the nation’s Senate, two places where women are scarce.

After that success, the duo wanted to reach higher and began thinking about entering the annual contest for the PEP. Alomaja suggested adding in the literacy component to round out the program.

The trio approached Ocek Eke, the director of global and local-service learning programs in the School of Engineering and Applied Science. He knew all three women, since Alomaja is majoring in bioengineering and Kollie and Aghayere had worked on programs with him, and he agreed to be their faculty mentor for the project.

Strella Biotechnology’s Biosensors Minimize Food Waste, One Apple at a Time

By Erica K. Brockmeier

BE Senior Malika Shukurova (left) with her partner Katherine Sizov, Strella Biotechnology

Bringing home a bad apple or two from the grocery store might not seem like a huge deal to the average consumer. But for producers and sellers of fresh fruits and vegetables, the staggering 40% of food that goes bad before it even reaches a store means mounds of wasted food and nearly $1 trillion in lost profits.

Now, thanks to a 2019 President’s Innovation Prize (PIP) award, seniors Katherine Sizov of Alexandria, Virginia, and Malika Shukurova of Samarkand, Uzbekistan, plan to address the issue and optimize the produce supply chain. The prize will help them grow their novel biosensing technology startup company Strella Biotechnology.

Sizov, who is majoring in molecular biology, likes to ask everyone the same question when talking about Strella: “How old do you think an apple in a grocery store is?” As it turns out, an apple from a store may have been in storage anywhere from a couple months to up to more than a year. “That’s one fact that you don’t really consider when you go into a store because you’re so used to seeing fresh fruit,” she says.

The idea for Strella came to life when Sizov, who was previously doing undergraduate research on neurodegenerative disorders, found herself reading papers outside of her main area of study and chatting with Shukurova about what she learned about food waste. The two friends had met during freshmen year through the Penn Russian Club.

That 40% of all fresh produce going to waste is what motivated Sizov. “I thought it was the most ridiculous number in the world,” she says. “This clearly is a problem that could be solved, and, since ag is a bio space, I thought we could use the technical knowledge that we have to solve the problem.”

Shukurova, a bioengineering major, quickly became interested in seeking a solution with Sizov. “At that time I was becoming increasingly interested in the technical aspects [of the problem], and more focused towards building a solution by sensing,” she says. Their complementary areas of technical expertise, and two years of friendship, led to a collaboration.

They soon found a potential approach: Ripening fruits release ethylene gas, and the amount of the gas correlates with a fruit’s ripeness. The challenge, however, is that man-made compounds do not bind ethylene with much specificity, so it’s a difficult gas to measure.

Strella’s solution? “Hack the fruit,” says Sizov, explaining that fruits can already measure ethylene themselves. Placing a ripe banana next to an unripe banana, for example, causes the unripe fruit to ripen more quickly. “Why reinvent the wheel? Let’s use what a fruit uses to sense ethylene,” she says.

After Sizov “hacked” the fruit and had a potential biosensor in hand, Shukurova’s experience and technical knowledge in bioengineering gave her knowledge on both the electronic and biological aspects of the problem. Their patent-pending sensor is now a “leading ripeness indicator” that Strella can monitor on a constant basis.

But bringing their biosensor to market means overcoming technical and biological challenges, including biosensor stability and powering the electrical components that collect data. Sizov and Shukurova put together a team of people with complementary knowledge, including Zuyang Liu, an electrical engineering master’s student; Reggie Lamaute, an undergraduate studying chemistry and nanotechnology; and Jay Jordan, who has previous experience in sales and market development in agriculture.

Strella biotechnology came together thanks to a number of programs and resources at Penn, including the Wharton VIP-Xcelerate, the Wharton VIP Fellows program, Weiss Tech House, the Wharton Undergraduate Entrepreneurship Club, the Penn Engineering Miller Innovation Fellowship, and courses offered as part of the Engineering and Entrepreneurship Program. Sizov and Shukurova also say that Penn’s openness to innovation and the numerous resources for would-be entrepreneurs has expedited their success.

Mentorship was also crucial for the success of their startup, with both naming Sevile Mannickarottu and their PIP mentor, Jeffrey Babin, as instrumental resources. Babin, who first met Sizov when she took his engineering entrepreneurship lab and who later served as her Wharton accelerator program advisor, says that Sizov was able to take skills she gained in the classroom and directly apply them in business scenarios. “She’s fearless in terms of picking up the phone and talking to strangers, gauging the market place, and taking on the tough issues in starting a company,” he says.
