Metallic gold is not completely inert towards biological tissues and cells. Cytotoxicity and immunotoxicity are concerns in various gold applications. This study shows that treating the surface of gold with OH• radicals renders the gold surface non-cytotoxic, as well as prevents any biocorrosion of gold implants by an immune reaction. The detoxification is discussed as resulting from the selective...
A new electrochemical assay has been developed which is based on quantifying the attack of OH. radicals on a self‐assembled thiol monolayer on electrodes in the presence and absence of antioxidants. The OH. radicals were produced in Fenton solutions. The radical scavengers diminish the concentration of the OH. radicals in the Fenton solution, and the extent of thiol layer destruction is monitored...
