Ultrasensitive and selective non-enzymatic glucose detection based on pt electrode modified by carbon nanotubes@ graphene oxide/ nickel hydroxide-Nafion hybrid composite in alkaline media

A new enzymeless glucose sensor has been fabricated and its electrocatalytic oxidation has been investigated in alkaline medium directly on the Pt Electrode modified by Activated carbon nanotubes @ graphene oxide/ nickel hydroxide-Nafion hybrid composite (PtACNT@GONHNPsNf). Under the optimized condition, the calibration curve is linear in the concentration range of 5-1100 µM using cyclic voltammetric method. The detection limit and sensitivity...
