    Abstract

    A gold nanoparticle-functionalised multi-walled carbon nanotube composite, fMWCNT-Aunano, was prepared by a simple reduction method using sodium borohydride and was used for sensing glucose non-enzymatically at neutral pH. The morphology and composition of the fMWCNT-Aunano hybrid were characterised by TEM, EDX and AA. TEM analysis indicated the gold nanoparticles to be mainly under 10 nm in size and both EDX and AA quantified the gold loading at 2% weight of composite. Constant potential amperometry was used for electrochemical detection of glucose and Nafion® membranes were employed to reduce interference from the commonly occurring AA and UA interferants, present in blood at high concentrations.
