Device designed to prevent heart attacks

Ruchi Pandya, high school student, 18, created a biosensor that can save lives by providing an up to 72-hour warning of an impending heart attack.
Using small carbon nanofibers, Pandya created a nanotechnology-based biosensor for cardiac health diagnostics. This means that this invention, a square, 1-centimenter, could eventually save lives by providing an up to 72-hour warning of an impending heart attack.
“The device uses a single drop of blood to detect certain protein concentrations that are indicators for cardiac arrest,” Pandya said. “Certain protein concentrations will spike in the bloodstream before a cardiac arrest occurs. The device I developed can actually detect quantities of these proteins in a person’s bloodstream”.
The student, from San Jose, California, visited the White House, on March 2015, for a science fair that was hosted by President Obama himself.
Pandya officially started her nanotech-based biosensor project in December 2013. This project became her unofficial extracurricular activity — besides going to school, she would log long hours in the lab to test and perfect her project.
Currently, Pandya is still working on fine-tuning her device and making it ready for her next big event — the Intel ISEF (International Science and Engineering Fair) — on May 10-15 in Pittsburgh, Pennsylvania. The competition includes 1,800 participants from more than 70 countries.
