  • Abstract:[WT]Aiming at the problem of inconvenience to carry and difficulty with power in-field electrochemical measurement,a portable cyclic voltammetry measurement system was designed based on aptamer-based biosensor developed by our laboratory.For overcoming the noise in the circuits effectively,a lock-in amplifier,potentiostat and program for phase sensitive detection were designed to extract weak signal.Experiment results showed that the system could implement cyclic voltammetry,which had higher SNR(signal noise ratio),the measurement precision of which could reach 1 μA.It had features of power saving,and simple eration,which could meet the requirement of in-field cyclic voltammetry measurement.
