摘要：

The electrochemical oxidation of DNA at a gold microelectrode has been investigated using cyclic voltammetry with a homemade microliter cell. Denatured DNA is adsorbed and oxidized more easily at the gold electrode than native DNA. The electrochemical oxidation of DNA also depends on its strand length. The DNA oxidation product adsorbs strongly on the gold electrode, so poisoning and inactivating its surface; the adsorbed product also inhibits electrooxidation of the gold surface.
