研制了一种用于电化学分析的集成信号处理电路的智能微流控DNA传感器。该传感器包括集成的电化学传感电极、微流体通道型反应器和用于电化学测量的运算放大器。微流体反应器采用层流原理。通常，对于电化学测量，相对大且昂贵的系统是必需的。在所制造的智能芯片中，集成了用于测量循环伏安图特性的信号处理电路，仅使用两个简单的电源就可以连续测量循环伏安图。
A smart microfluidic DNA sensor with an integrated signal-processing circuit for electrochemical analysis has been successfully fabricated. The sensor comprises an integrated electrochemical sensing electrode, a microfluidic channel-type reactor, and operational amplifiers for electrochemical measurement. The microfluidic reactor employs a laminar flow principle. Generally, a relatively large and expensive system is necessary for electrochemical measurement. In the fabricated smart chip, signal-processing circuits for measuring cyclic-voltammogram characteristics are integrated, permitting cyclic-voltammograms to be successively measured, using only two simple sources of electrical power.
