摘要：

Scanning tunneling microscopy is used to image adsorbed products resulting from the electro-oxidation of dihydronicotinamide adenine dinucleotide (NADH) on highly oriented pyrolytic graphite. Defined images of the passivated layer, with scattered protrusions of different sizes and shapes, are observed. The exact structure is strongly dependent on the anodization time, NADH concentration, or anodization potential, with higher surface coverages being observed for higher charges (passing during the anodization). The implications of these findings on the analytical/sensing utility of nicotinamine coenzymes are discussed.
