<p>Carbon-based electrode materials have been widely applied for the electrochemical analysis of biomolecules. In addition to traditional carbon electrodes such as glassy carbon and carbon paste, a wide variety of carbon materials such as nanocarbons and boron doped diamond (BDD) electrodes have been employed for electrochemical analysis and biosensors in the last 25 years. Of the carbon electrode materials, carbon films are practically advantageous because they can be fabricated reproducibly with a wide range of shapes and sizes. In this paper, we report the application of sputter deposited nanocarbon film electrodes for the electrochemical analysis of biomolecules. The pure nanocarbon film electrodes have been employed for detecting DNA methylation, and lipopolysaccharides (LPS). Nitrogen-containing carbon films show improved electrochemical activity for biomolecules and excellent biocompatibility with interferents such as proteins. Metal nanoparticle embedded or modified carbon film electrodes show excellent electrocatalytic performance with sugars.</p>
