Peroxidase-like activity of acetylcholine-based colorimetric detection of acetylcholinesterase activity and an organophosphorus inhibitor

. This strategy was also demonstrated to be applicable for pesticide detection in real samples. Meanwhile, the sensing platform can also be implemented on test strips for rapid and visual monitoring of OPs. Thus, this extremely simple colorimetric strategy without the addition of other exogenous catalysts holds great promise for on-site pesticide detection and can be further exploited for sensing applications in the environmental and food safety fields.
