Electrically Addressable Biomolecular Functionalization of Conductive Nanocrystalline Diamond Thin Films

Electrically addressable biomolecular functionalization of diamond thin films is achieved by growing a conductive diamond thin film on molybdenum electrodes, functionalizing to produce surface nitro groups, and electrochemically reducing the nitro groups on specific diamond-coated electrodes to primary amines. The amines are then used to covalently link DNA to the surface.
