A novel acetylcholinesterase biosensor based on gold nanoparticles obtained by electroless plating on three-dimensional graphene for detecting organophosphorus pesticides in water and vegetable samples

In this study, a novel acetylcholinesterase (AChE) biosensor for the detection of organophosphorus pesticides (OPs) was developed based on a film of gold nanoparticles/three-dimensional graphene (AuNPs/rGO).
