A novel construct of an electrochemical acetylcholinesterase biosensor for the investigation of malathion sensitivity to three different insect species using a NiCr₂O₄/g-C₃N₄ composite integrated pencil graphite electrode

Abstract

An innovative electrochemical assay has been established to determine pesticide sensitivity against acetylcholinesterase and possible toxicity against insects. The analytical efficiency of three common insect AChEs was determined through this method.

Potential protective effects of thyme (Thymus vulgaris) essential oil on growth, hematology, immune responses, and antioxidant status of Oncorhynchus mykiss exposed to malathion

“…The bioconcentration factor values for some fish species have been reported (Howard, 1991;Deka and Mahanta, 2016). Upon entering an organism's body, malathion binds to acetylcholinesterase enzyme (AChE) at the end of the nerve system, thus over-stimulating the nervous system (Bilal et al, 2022). Reduction of antioxidant defense capacity due to oxidative stress and increase in lipid peroxidation (Abdel-Salam et al, 2016) are other proposed mechanisms for malathion toxicity.…”
