A team of Stanford University students and faculty has been selected as one of five Distinguished Award Prize winners in the Nokia Sensing XCHALLENGE, a global competition to catalyze breakthrough medical sensing technologies that will ultimately enable faster diagnoses and easier personal health monitoring.
The Stanford team was recognized for developing a hepatitis B blood test that can be analyzed in minutes using the microprocessor in a smart phone.
The current prize recognizes a 12-month effort by four PhD students – mechanical engineers Daniel Bechstein and Jung-Rok Lee, and electrical engineers Joohong Choi and Adi W. Gani – to create a mobile version of a technology that [EE Professor] Wang and other Stanford researchers have been developing for years.
In essence, the researchers graft magnetic nanoparticles onto biological markers. In this case they are interested in two biomarkers. One is the hepatitis B virus, called the antigen. The other is the antibody that fights hepatitis B. The magnetic particles are the homing beacons that allow instruments to track these biomarkers.
