| 中文摘要 | flavin adenine dinucleotide (fad) was modified onto the highly oriented pyrolytic graphite (hopg) and glassy carbon electrode (gee) surfaces with three methods, respectively. corresponding image analysis for fad-modified hopg surfaces has been performed by scanning tunnelling microscope (stm) for the first time. the molecular resolution stm image of fad adsorbed on the freshly-cleaved hopg was obtained, the quantitative size determination suggests that the fad molecules adsorb side lying on the substrate surface. the anodization treatment of hopg surface yields many pits, which were clearly observed under stm. these pits provide active sites on the hopg surface for modification and the treated hopg can strongly adsorb fad molecules, the latter exhibiting an irregular cluster structure on such a surface. when fad was electrochemically deposited on the substrate surface, a chain structure was successfully observed. the adsorbed fad on anodized glassy carbon electrode (gee) surface can effectively catalyze the reduction of glucose oxidase, hemoglobin and myoglobin, with a large decrease in the overvoltage, whereas the deposited fad film exhibits excellent electrocatalysis towards dioxygen reduction. |
