Penn students win over $70,000 to revolutionize water and drug testing
Four students at the University of Pennsylvania have an idea they believe will transform drug and water testing — and they just won more than $70,000 to help launch it.
Driving the news: ToxiSense, a group founded by the Penn freshmen, took home the top prize at the university's Venture Lab Startup Challenge last month for a proposed model to test certain pharmaceutical products and water for harmful endotoxins.
- ToxiSense was awarded $70,000 in cash and at least $10,000 worth of additional support services.
The big picture: Both biopharmaceutical products and drinking water must be tested for bacterial endotoxins, which can cause sickness and even death.
- The biomedical industry is heavily reliant on the use of horseshoe crabs' blue blood, which is both expensive and environmentally damaging, to test for those toxins.
- A gallon of the blood can cost as much as $60,000.
How it works: ToxiSense genetically engineered a plant — a weed related to cauliflower — to glow based on the amount of endotoxins present, CEO and co-founder Aravind Krishnan told Axios.
- Krishnan said his group could produce a single endotoxin test for less than 50 cents, compared to $19 per test for those that include horseshoe crab blood.
Zoom in: ToxiSense was among eight finalists competing in the annual startup challenge. Other groups also took home cash awards and prizes to advance their ideas.
- ToxiSense's members also include Udit Garg, Andrew Diep-Tran and Aarush Sahni.
What they're saying: Krishnan said he hopes the groups idea will be a more cost-effective and sustainable solution to endotoxin testing and will expand access to under-developed countries.
- The group aims to funnel the prize money into developing the proposal this summer.
- "We foresee immense potential for our product," he said. "Basically, every single person on the planet right now relies on these horseshoe crabs, so we are excited to usher in a new era of bacterial toxin testing."
What's next: The group will continue to research and hone the idea this summer and develop a test kit.
- The students hope to pitch their idea to water testing customers in 2023 and eventually sell their product to biopharmaceutical companies as early as 2024, after receiving required federal approvals.
