Electrochemical properties of sputter deposited diamond-like carbon film and graphite-like carbon film electrodes containing metal nano-particles

摘要

Various kinds of new carbon materials have been developed for electroanalysis and electrochemical sensor applications.Boron-doped carbon film has a wide potential window and a stable baseline current and is now used to measure various analytes [1,2].A simple film formation process such as low temperature film deposition is required for a number of applications including film electrodes on plastic substrates.We prepared diamond-like carbon film by the electron-cyclotron-resonance plasma (ECR) sputtering method [3,4].This film is amorphous-like and has an extremely flat surface.Here,we report the structure and electrochemical properties of ECR sputter deposited film.In addition,we describe the electrochemical properties of carbon film electrodes containing metal nano-particles designed to detect various analytes such as neurotransmitters.
