This work describes an effective electrodeposition method for generating gold plasmonic electrodes which are further used for detecting glucose in solution without the presence of any enzymes ( Gox). Under light irradiation, the electro-catalytic oxidation of glucose on the electrodeposited gold nanoparticle (AuNP) surfaces has been investigated. The wavelength-dependent electrochemical oxidative current intensity implies that the hot carriers transferred from the excited plasmonic AuNPs to the absorbed molecules are responsible for enhancing electro-catalysis performance. |
