Colorimetric Detection of Deltamethrin Pesticide from Biological Samples Based on the Peroxidase-Mimc Catalytic Activity on MnO₂/SnO₂

Abstract

For the creation of chromogenic agents, an exogenous catalyst can be used, which can enhance complexity and interfere with the colorimetric detection of Deltamethrin (Dmp). This study revealed that MnO2/SnO2 nanocomposite to mimicked peroxidase activity, leading to the devel Deltamethrinment of a simple and reliable sensing system containing ATCh-TMB-H2O2 for the selective and sensitive assay of AChE activity and its inhibitor Deltamethrin, which is described in detail in another publication. As acetylcholine hydrolysis was shown to modify the peroxidase-like activity of acetylcholine, this activity was used to measure Deltamethrin with exceedingly sensitively with a low limit of (LOD) of 4.0 ng mL-1. The AChE inhibition allowed for the detection of Deltamethrin with a low-order. The real-world samples can be successfully identified using this method.
