Insulin sensor based on nanoparticle-decorated multiwalled carbon nanotubes modified electrodes

Abstract

Insulin sensors based on glassy carbon electrodes, modified with nafion-multiwalled carbon nanotubes decorated with nickel hydroxide nanoparticles (Ni(OH) 2 NPs/Nafion-MWCNTs/GC), were prepared by electrochemical deposition of Ni(OH) 2 NPs from a dinuclear paddle-wheel Ni monothiocarboxylate complex on the MWCNTs/GC surface. The size and distribution of the 1
