The Characterization of Chitosan-ZnO Nanoparticles Modified Screen-Printed Copper Electrodes as the Analytical Sensor

Abstract

Characteristics of chitosan-ZnO-modified screen-printed copper electrodes showed good sensitivity as a sensor which characterized by using cyclic voltammetry. The copper electrode was prepared for the sensitivity testing before being used as a sensor substrate material, the tests carried out in sodium phosphate buffer solution (BSP), the use of BSP as a standard test in this study.
