The device, developed by the researchers at Columbia University School of Engineering and Applied Science, led by Samuel K. Sia, can perform a point-of-care test that simultaneously detects three infectious disease markers.
The device replicates, for the first time, all mechanical, optical and electronic functions of a lab-based blood test, they said.
The device performs an enzyme-linked immunosorbent assay (ELISA) without requiring any stored energy: all necessary power is drawn from the smartphone. It performs a triplexed immunoassay not currently available in a single test format: HIV antibody, treponemal-specific antibody for syphilis, and non-treponemal antibody for active syphilis infection.
