Light-Emitting Bioprobe Fits in a Single Cell, Stanford University Study  
2/14/2013 10:08:59 AM

If engineers at Stanford have their way, biological research may soon be transformed by a new class of light-emitting probes small enough to be injected into individual cells without harm to the host. Welcome to biophotonics, a discipline at the confluence of engineering, biology and medicine in which light-based devices -- lasers and light-emitting diodes (LEDs) -- are opening up new avenues in the study and influence of living cells.
