Paper Strips as 'Microfluidic' Devices for Rapid Medical Diagnostics and Chemical Analysis

Caption

Researchers have invented a technique that uses inexpensive paper to make "microfluidic" devices for rapid medical diagnostics and chemical analysis. To demonstrate the new concept, the researchers created paper strips containing arrays of dots dipped in luminol, a chemical that turns fluorescent blue when exposed to blood. Blood was then sprayed on the strips, showing the presence of hemoglobin.
