A highly sensitive electrochemical OP biosensor based on electrodeposition of Au–Pd bimetallic nanoparticles onto a functionalized graphene modified glassy carbon electrode

Abstract

An Au–Pd bimetallic nanoparticle and ionic liquid functionalized graphene–chitosan nanocomposite (Au–Pd/IL-GR–CHI) modified glassy carbon electrode has been developed for the highly sensitive determination of organophosphorus pesticides.
