Voltammetric Responses of On-Chip Glucose Oxidase Immobilized Diamond-Like Carbon Electrodes
Abstract(#br)This work reports the fabrication and electrochemical characterization of the polydimethylsiloxane (PDMS) microfluidic three-electrode cell chip utilizing diamond-like carbon (DLC) films as a working electrode for amperometric biosensing applications. The DLC films are prepared by a radio-frequency plasma enhanced chemical vapor deposition (RF-PECVD) technique with CH4 as a carbon precursor gas. Raman spectroscopy is employed to characterize the film structures.
