电化学传感器检测植物生长调节剂的研究进展

近年来,植物生长调节剂(PGRs)的检测方法备受研究者广泛关注。由于电化学传感器具有较高的灵敏度和选择性、响应时间短、成本低、方便携带等优点,在现场快速检测中受到研究者的青睐。从电化学传感器检测PGRs的4个方面进行了总结:1)直接电化学行为传感,主要是通过不同的修饰材料对电极进行增敏,从而实现对具有电化学活性的PGRs进行直接检测;2)电化学生物传感,主要通过酶和抗原抗体对PGRs进行特异性识别;3)光电化学传感,主要是利用具有光催化性能的材料实现对电化学活性较差的PGRs进行光电转化检测;4)分子印迹电化学传感,通过构建能够特异性识别PGRs的聚合物薄膜从而进行专属检测。同时对电化学传感器现状进行了阐述以及对未来发展趋势进行展望。

Progress on the Detection of Plant Growth Regulators by Electrochemical Sensors

In recent years, the detection methods of plant growth regulators(PGRs) have attracted extensive attention.Electrochemical sensors are favored in the field of rapid detection because of their high sensitivity and selectivity, short response time, low cost, and convenient carrying.This work summarizes the four aspects of PGRs detection by electrochemical sensors.(1)Direct electrochemical behavior sensing, which mainly uses different modified materials to sensitize the electrode, so as to realize the direct detection of electrochemically active PGRs.(2)Electrochemical biosensing, PGRs is specifically recognized by enzymes and antigens and antibodies.(3)Photoelectrochemical sensing, which mainly uses materials with photocatalytic properties to achieve photoelectric conversion detection of PGRs with poor electrochemical activity.(4)Molecular imprinting electrochemical sensing, by constructing a polymer film that can specifically recognize PGRs for exclusive detection.And it was explained as well as the future development trends and prospect.
