Optical Techniques Control Fluid Flow

June 22, 2010
Optical Techniques Control Fluid Flow Physicists at the Georgia Institute of Technology have demonstrated a new optical technique for controlling the flow of very small volumes of fluids over solid surfaces. The technique, which relies on changes in surface tension prompted by optically-generated thermal gradients, could provide the foundation for a new generation of dynamically reprogrammable microfluidic devices. This research was supported by National Science Foundation CTS 02-01610. (Date of Image: August 2003)
