Sputtered Nanocarbon Film for Electroanalysis
Introduction. Recently, we have developed a nano-hybrid carbon film consisting of nano-crystalline sp2 and sp3 mixed bonds formed by electron cyclotron resonance (ECR) sputtering method. The film structure is quite different from graphite, boron-doped diamond (BDD) or diamond-like carbon 1. The ECR nano-carbon film electrode has excellent properties including an atomically flat surface, a wide electrochemical potential window, and little surface fouling while maintaining relatively high electrode activity 2-4. In addition, the electrochemical properties of the carbon films can be controlled by terminating the surface with different atoms such as oxygen and fluorine 5-6. Due to such electrochemical performance, this film electrode can be considered for various applications such as enzyme biosensors, DNA detection. Here, we introduce some of the examples of electroanalytical applications using ECR nanocarbon films.
