Electrochemical bisphenol A sensor based on carbon nanohorns

Abstract

Herein, a new carbon material, carbon nanohorns (CNHs), was firstly employed as the sensing element to fabricate a simple electroanalytical platform for detecting food born contaminants. Bisphenol A (BPA) was chosen as the model to be tested in this sensing platform. The detailed electrochemical behavior of BPA was investigated on the modified electrode and its kinetic parameters were further calculated. The relative results pointed out that CNHs, which have a similar electrocatalysis effect as previously reported carbon materials, like graphene and carbon nanotubes, could obviously amplify the electrochemical oxidation response of BPA because of its unique and charming properties. The experimental conditions affecting the BPA determination were optimized. The relative results indicate the potential application of CNHs in designing sensitive and convenient sensors for the rapid and on-site monitoring of food born contamination.
