AviSafe, University of Pennsylvania

Team Members: Haichuan Yang and Yuwei (Amy) Guo; Advisers: Ocek Eke and Henry Daniell

Preventing avian influenza outbreaks: Easily transmitted and resistant to vaccines, avian influenza is a global concern. Five major outbreaks have occurred in the U.S. over the past decade, with the most recent causing over $3 billion in losses to poultry growers. AviSafe’s FluShield antiviral poultry feed additive is a robust, low-cost, low-maintenance method for introducing immunity into large poultry operations. It can prevent infections, keep the virus from spreading to neighboring farms or wild birds, and reduce the chance of a new viral strain transitioning from poultry to humans.


Bronchosleeve, Johns Hopkins University

Team Members: Sneha Batheja, Ria Jha, Charlie Almoney and Arijit Nukala; Adviser: Brijen Joshi

Supporting safety in surgery: One-lung ventilation (OLV), a procedure that provides surgeons with access to organs obstructed by an inflated lung, is required in 98% of pulmonary and cardiothoracic surgeries. However, current OLV devices have a 40% failure rate and a high probability of causing postoperative complications. The Bronchosleeve is a flexible yet sturdy device presenting many advantages over existing OLV devices. It is easy to insert, won’t dislodge during surgery and aids visualization with a bronchoscope. In addition to addressing disparities and reducing patient injuries, it could decrease surgical time by 40% and save hospitals over $45,000 per procedure.


FADpad, Georgia Institute of Technology

Team Members: Netra Gandhi, Rhea Prem, Ethan Damiani and Girish Hari; Adviser: Wendy Cocke

Accessible, at-home diagnostics: One of the most common diagnostic tools in women’s health, the Papanicolaou test, or Pap smear, is often uncomfortable and regarded as an invasion of privacy, and it is even stigmatized in some cultures. FADpad is an at-home menstrual blood screening tool that allows users to collect their personal health information safely, comfortably and privately. Targeted to users with limited access to the healthcare system, it could help address health disparities and prevent early deaths from cervical cancer among people who menstruate.


NucleoTide, Duke University

Team Member: Daniel Collins; Adviser: Peter Nguyen

Efficiently monitoring ocean health: Over the past several decades, a combination of natural and human-caused factors has led to an increase in the frequency, duration, size and impact of harmful algal blooms (HABs), with a global economic impact estimated at more than $8 billion annually. NucleoTide is a molecular diagnostic platform that uses CRISPR-based biosensors to rapidly identify marine pathogens and HABs. With a low-cost, hand-held device that filters and processes water samples, it enables lab-free, on-site ocean health monitoring and provides results in less than an hour, offering both economic and environmental benefits.


ToxiSense, University of Pennsylvania

Team Members: Andrew Diep-Tran, Aravind Krishnan, Udit Garg and Aarush Sahni; Adviser: Ping He

A sustainable solution for endotoxin detection: Many pathogenic bacteria produce lipopolysaccharide compounds called endotoxins. These are toxic to humans, causing sicknesses including septic shock — the leading cause of death in hospitals — which results in 11 million deaths annually, or one in five deaths worldwide. An alternative to current expensive and unsustainable testing methods, which use horseshoe crab blood, ToxiSense is an engineered plant cell-based biosensor that detects bacterial endotoxin contamination in medical products and water. It can be applied in the biopharmaceutical industry and for waterborne disease testing. Each test kit offers substantial advantages in accuracy, sustainability and ease of use.



Bioadhesive Ultrasound, Massachusetts Institute of Technology

Team Member: Chonghe Wang; Adviser: Xuanhe Zhao

Pioneering, long-term medical imaging: In a landscape dominated by episodic medical scans, the Bioadhesive Ultrasound (BAUS) patch is a leap forward. This innovative, wearable device adheres to the skin, offering continuous, medical-grade imaging of key internal organs over extended periods. Promising superior patient care, as well as cost and time efficiency, it reveals disease progression in real time and long term, ensuring timely interventions and optimal outcomes. The BAUS patch could make a revolutionary impact by merging the convenience of wearables with medical-grade imaging for a new era of patient-friendly, sustainable healthcare, in which medical imaging is continuous, profound and wearable.


Cerebral Aneurysm Test (CAT-7), University of Pittsburgh School of Medicine

Team Member: Adi Mittal; Advisers: Robert M. Friedlander, Kamil Nowicki

Enabling earlier aneurysm diagnoses: Affecting an estimated 6.7 million people in the U.S., a cerebral aneurysm (CA) can cause neurological problems and can rupture, leading to life-altering or fatal brain bleeds. Diagnosis can be a long process, current tools are invasive, expensive and potentially toxic, and ruptures often occur before diagnosis or treatment. Cerebral Aneurysm Test (CAT-7) is the first simple, whole blood-based diagnostic test to detect the formation of a CA. It is noninvasive, less expensive, more accurate, safer and able to be used earlier in the care process.


Entropic Biosciences Inc., University of California, Los Angeles
