(PhysOrg.com) -- Bioengineer Samuel Sia has designed a handheld device which uses a microchip to perform intricate medical tests for illnesses such as sexually transmitted diseases or prostate cancer. It needs just a drop of blood to diagnose a patient, and results come back in 12 to 15 minutes. This lab-on-a-chip method miniaturizes and simplifies the once time-consuming system of analyzing diagnostic tests results.
