Roland Piquepaille writes "Researchers from the University of Texas M.D. Anderson Cancer Center have devised a new programmable biochip which can manipulate nanoliter droplets. In this article, Technology Research News says that this biochip "uses an array of electrodes to place water droplets on a surface, insert substances into the droplets, and move and merge the droplets." The device, which has no moving parts, could help to identify pathogen agents in the field. Even if the researchers plan to have a protoype ready by the ned of the first half of 2004, they don't expect to have a miniaturized, fully-automated device available for field testing before two years. This overview contains more details and a picture of the biochip."
