Temperature Control System for Biochemical Reactions in Microchip-Based Devices JING Gaoshan, ZHANG Jian, ZHU Xiaoshan, FENG Jihong, TAN Zhimin, LIU Litian, CHENG Jing 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. Keywords temperature control; microreactor; microchip; polymerase chain reactions (PCR)
