Abstract
Fabrication of Non-enzymatic Ni–Au Alloy Nanowire Glucose Sensor
Highlights
An increasing number of people suffer from diabetes
We have focused on the fabrication of a non-enzymatic glucose sensor
Glucose, amino acid (AA), and urea were purchased from Sigma-Aldrich
Summary
An increasing number of people suffer from diabetes. rapid and precise glucose sensors are becoming increasingly important. Electrochemical glucose sensors can be divided into enzymatic[4,5] and nonenzymatic glucose sensors.[6,7] enzymatic glucose sensors have a high sensitivity and a large measurement range, they are affected by pH, temperature, and humidity.[8,9] The. most serious problem is that their lifetime is too short for long-term use by diabetes patients. Noble metal electrodes including Au[10] and Pt have been used in glucose sensing. They have a low sensitivity and a high cost. Multilayer[9,11,12] and alloy structures[13,14,15] have been used to solve the problems of noble metal electrodes because of their synergistic effect. The oxidation peak and the sensitivity of the sensing electrode were investigated in 0.1 M NaOH by cyclic voltammetry (CV) and observing the amperometric response
