成功制作了具有电化学分析信号处理电路的智能微流控DNA传感器。所提出的传感器是集成电化学传感电极、微流体通道型反应器和用于电化学测量的运算放大器。微流体型反应器采用层流原理。通常，电化学测量需要相对较大且昂贵的系统。在所提出的智能芯片中，集成了测量循环伏安图特性的信号处理电路，并且仅通过两个简单的电源连续测量循环伏安图。
Smart microfluidic-DNA sensor with the signal processing circuit for electrochemical analysis is fabricated successfully. The proposed sensors are integrated electrochemical sensing electrode, microfluidic channel type reactor and operational amplifiers for an electrochemical measurement. Microfluidic type reactors were used with a laminar flow principle. Generally a relatively large and expensive system is necessary for electrochemical measurement. In the proposed smart chip, signal processing circuits to measure a cyclic-voltammograms characteristics were integrated, and the cyclic-voltammograms were successively measured by only two simple electric power sources.
