Portable, Battery Powered Viral Detector Takes Only a Drop of Blood

The technology relies on strips of a paper-like material that can become saturated and can slowly move a liquid from its one end to another. The electronics are used to mix a small blood sample with a buffer solution and to then heat it as it moves across the paper.

A band shows up on the end of the...
