Image of the Day: Glowing Bacteria On a Chip
Using new nanochip technology, scientists can measure the light emitted by engineered fluorescing bacteria.
A laser arouses fluorescence from engineered light-emitting E. coli bacteria suspended within a microfluidic chip device. The bacteria flicker as they move, and their fluorescent signal propagates throughout the device. HEBREW UNIVERSITYSee O.
