摘要 本文设计制作温度可控全透明PDMS微通道阵列芯片。采用具有光学透明的PDMS和ITO导电玻璃,分别加工微通道阵列及加热器并利用真空氧等离子实现芯片的键合。芯片的温度控制部分采用单片机AT89C51为核心,通过对PID温度控制算法进行修正,芯片的温度控制精度可达到±0.2℃。该芯片可用于DNA分析或细胞培养。 In this paper, we fabricated a transparent PDMS microchannel-array chip of temperature controlled. Using transparent PDMS and conductive ITO glass, we fabricated microchannel-array and heater and implemented bonding of the chip utilizing vacuum oxygen plasma. The temperature control system of chip was based on a singlechip-AT89C51, in which the PID arithmetic was implemented and further modified, the temperature control accuracy of 0. 2℃ could attained. This chip can be used in the fields such as DNA analysis or cell culture.
