DEVICE FOR CONTROLLING OF MICROFLUIDIC AND METHOD OF FABRICATING AND OPERATING THE SAME

摘要

A microfluidic control device is provided to perform the minute control of fluid sample by bond of natural flow and forced flow, entire change or strong washing. A microfluidic control device(100) comprises a first substrate and a second substrate. The first substrate comprises sensing electrode(212), heaters and temperature sensors. The second substrate has fluid inlet(112), fluid inlet chamber unit(114), flow path unit(116), reaction chamber unit(118), valve unit, pump unit, and waste water chamber unite(130). The reaction chamber unit corresponds to the sensing electrode. The valve unit corresponds to one of heaters and temperature sensors. A method for operating the microfluidic control device comprises: a step of injecting fluid sample; a step of transferring the fluid sample to the sensing electrode; a step of stopping the flow of fluid sample; and a step of discarding the fluid sample.
