In this paper, a new electrokinetic pump （EOP） system with polycarbonate nanoehannel membrane sandwiched between two membrane holders was constructed. The pump was tested with water and phosphate buffer at 1-6 V applied voltage, the maximum pressure and flow rate are 0.32 MPa （3.2 atm） and 4.2 μL/min for phosphate buffer, respectively. This proof-of-concept pump shows its potential use for drugs or chemical agents delivery by the usage of different membrane materials.展开更多

The flow speed could be precisely adjusted by a micropump, and the flow direction could be controlled by switching valves. The complete operation was computer controlled. The control system for the micropump and microvalves is discussed here. This control system can be combined with other biochip devices to construct a micro total analysis system (μTAS). 展开更多
