MICROFABRICATED PHASE CHANGE LATCHED VALVE FOR INTEGRATED DEVICES

摘要

Microfabricated Phase-change valves based on the localized phase transition of the valve seat have been developed for use on chemical analysis device. Valves as small as 1.3 millimeters in length in a 50μm x 500μm channel have been tested. These biocompatible valves have been used to seal 240 nL reaction chamber to perform PCR. The advantage of these valves include simple fabrication, electronic actuation and biocompatibility.
