[Show abstract][Hide abstract] ABSTRACT: A silicon-glass chip based microreactor has been designed and fabricated for biochemical reactions such as polymerase chain reactions (PCR). The chip based microreactor has integrated resistive heating elements. The computer-controlled temperature control system is highly reliable with precise temperature control, excellent temperature uniformity, and rapid heating and cooling capabilities. The development of the microreaction system is an important step towards the construction of a lab-on-a-chip system.
[Show abstract][Hide abstract] ABSTRACT: A micro fluidic system was developed and used for cell isolation on biochips. 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).
