Date Started


Project Stage: Select the description below that best applies to your approach.

  • Idea (hoping to get started in the future)

1. Personal Journey: What’s the story behind why you decided to start this project? NOTE: All applications must include a 1 minute video that answers: “I am stepping up to make change because..."

Last year was very tense as my dad had a perpetual headache. Numerous times, it seemed as if he had a minor stroke, however the primary care physicians were unable to provide a conclusive answer. This incited my curiosity in researching novel ways to detect and diagnose immediately without expensive CT scans or MRIs. This way, specialized treatments can have greater success rates and the overall survival of the patient is more guaranteed. As I investigated further, I realized how important it was that chemicals were released through the respiratory system during a stroke. With a nano sensor device, the chemical composition of the breath can easily identify abnormalities that provide hard evidence that a stroke occurred within the last 24 hours. This would be extremely helpful in developing countries where CT scans and MRIs are not readily available.

2. The Problem: What problem are you helping to solve?

The lack of easily accessible equipment that is low-cost is the problem I am trying to solve. The nano sensor device would be much more effective in determining whether a patient has an illness.

3. Your Solution: How are you planning to solve this problem? Share your specific approach.

I am planning to create a nano sensor during the summer at UPenn. The air trapped in the tube or balloon will pass through the nano sensor with specific chemical markers which measures the concentrations of certain chemicals like acetone to identify abnormality in the patient’s body. This is then converted to patient diagnoses.

4. Example: Please walk us through a specific example of what happens when a person or group gets involved with your project.

When a patient breathes into a tube-like end, the chemicals in the exhaled breath are analyzed against chemical markers with a nano sensor. This can be compiled into a readable format through basic software.

5. The X Factor: What is different about your project compared to other programs or solutions already out there?

This is a low-cost, readily accessible solution for many diseases like strokes and diabetes. Currently, a patient with diabetes must do a blood test, sometime twice a day by pricking their finger. This is very uncomfortable and in some cases, people skip or try to avoid these tests causing more complications in the long run. In addition, as blood tests are being done at home, there is a greater risk of infection. Our device will eliminate the shortcomings of the current devices.

6. Impact: How has your project made a difference so far?

Our project is currently in the idea phase. However, the testing at various hospitals and clinics will take our idea to the next step and will improve the device.

7. What’s Next: What are your ideas for taking your project to the next level?

I have planned time during the summer to work with professors at UPenn (since this college is currently active in this area of building diagnostic nano sensors). At the lab, I also am planning to begin building the actual nano sensor. After the physical model, that sensor will need analytical software to synthesize the chemical results into readable format.

8. Future Support: What are the resources needed to make your vision a reality?

Monetary funding to create a physical model, and resources required to develop software.

9. Finances: If applicable, have you mobilized any of the following resources so far?

  • Friend support
  • Family support

10. Ripple Effect: Please share some ideas of how you could partner with other changemakers or involve other young people as leaders in making a difference.

I could collaborate with change makers who are experts in software development and are interested in biomedical sciences. We can also plan to test at different clinics and hospitals in order to tweak and confirm the results of the device.

Great Idea!

Thank you Brittany! I also liked your idea and replied to it previously - best of luck!

This idea is amazing! We believe that you have indeed found a novel way to identify diseases and illnesses within patients before it is too late. Our understanding of your idea is that it is essentially a Breathalyzer test, only it will detect harmful/abnormal chemicals in exhaled breath as opposed to alcohol content. This seems simple, functional, and affordable. We hope your idea comes to life, as it would truly make a huge positive impact on the medical community. Our idea, Cocoon: Return, Restore, Reignite, is a campaign we are starting to encourage and allow young people like ourselves to go outside and spend more time in nature. In our submission, we discuss why being in nature is so important for our emotional, mental, and physical health, and tying it back to your idea, a lot of diseases can be prevented if we are committed to a healthy lifestyle. We'd love it if you checked it out at
Thank you again for sharing this wonderful idea! We hope it will go far.

Hi Vanya! Thank you for your kind words...I read through your proposal and I was pleasantly surprised by the method Cocoon is using to help reinvigorate teenagers who need it the most. I definitely agree that living a healthy lifestyle is crucial towards prevention of diseases. Wishing you the best luck!

Amazing work! Our project is also based in developing countries (girls' education), so it is great to see that your efforts have a similar focus. I think the accessibility of your design is perfect for such countries, but was wondering how long one of these devices lasts. If it is able to work for only a temporary amount of time, is it possible to construct the device out of recyclable/decomposing materials? That way, it is great for both human health and environmental health.
All in all, this is a fantastic idea and I wish you luck in this summer with your research!

Thank you Hannah and Zoha! These devices will actually last a very long time (5 years or so), think of it similar to Asthma inhaler chamber (tube). I think using recyclable/decomposing materials still is a great idea!
Wish you guys good luck too! Great initiative!
