“…Therefore, some OPs sensors have been established based on the inhibition mechanism of AChE or other technologies, for example, bi-enzymes of AChE and choline oxidase (Gao, Tang, & Su, 2012;Meng, Wei, Ren, Ren, & Tang, 2013;Zheng, Li, Dai, Liu, & Tang, 2011). Du et al reported a sensor for electrochemical quantification of enzymatic inhibition for biomonitoring of OPs (Du et al, 2011). But such inhibition sensors are not selective to OPs since AChE activity is also inhibited by carbamates pesticide .…”
