Diagnosis By Patterned Paper: Photoprinted Paper Supports Simultaneous Microscale Diagnostic Tests

... G. Whitesides and his team at Harvard University have developed a prototype for an inexpensive, highly practical rapid test that can be used to carry out several biological tests simultaneously on a single drop. As they describe in the journal Angewandte Chemie, their tests are based on tiny pieces of paper onto which defined, millimeter-sized channels are printed. ...
