基于纳米铁氰化镍修饰二氧化钛纳米管阵列电极的非酶葡萄糖传感器
An Amperometric Non-enzymatic Glucose Sensor by Nickel Hexacyanoferrate Nanoparticles Modified TiO2 Nanotube Arrays
摘要
Abstract
A non-enzymatic glucose sensor was developed by nickel hexacyanoferrate nanoparticles modified TiO2 nanotube arrays (TNTs). Ni nanoparticles were deposited on TNTs by pulsed electro-deposition method. Ni nanoparticles was converted to nickel hexacyanoferrate (NiHCF) nanoparticles by cyclic voltammetry in a solution containing [Fe(CN)6]3-. The electrochemical characteristics of the sensor were studied by cyclic voltammetry (CV). The non-enzymatic sensor shows significantly higher electrocatalytic activity to the oxidation of glucose in 1 mol/L NaOH alkaline solution The sensor response is highly sensitive (663 nA/(mmol· cm2) with a wide linear range (up to 23 mmol/L). The linear range is 2X 10-3 - 1. 0 mmol/L for the low concentration measurement with low detection limit of 0. 5 jimol/L (S/N=3).关键词
