Synthesis of gold nanoparticles using cefopernazone as a stabilizing reagent and its application

Abstract

Synthesis of gold nanoparticles using cefopernazone as a stabilizing reagent for a sensor was proposed. The gold nanoparticles were characterized by scanning electron microscopy, transmission electron microscopy, infrared spectrometry,ultraviolet- visible spectrophotometry, powder X-ray diffraction and cyclic voltammetry. The catalytic properties of gold nanoparticles on the glassy carbon electrode for dopamine were demonstrated. The results indicate that gold nanoparticle the modified electrode by means of electrochemical synthesis has an excellent repeatability and reproducibility. © 2012 by ESG.
