摘要

金属金对生物组织和细胞不是完全惰性的。细胞毒性和免疫毒性在各种金的应用中受到关注。本研究表明，用OH?自由基使金表面无细胞毒性，并防止免疫反应对金植入物的任何生物腐蚀。讨论了由于活性金原子从表面选择性溶解而产生的解毒作用。

Detoxification of gold surfaces by OH• treatment

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 dissolution of active gold atoms from the surface.

期刊介绍： Gold Bulletin is the premier international peer reviewed journal on the latest science, technology and applications of gold. It includes papers on the latest research advances, state-of-the-art reviews, conference reports, book reviews and highlights of patents and scientific literature. Gold Bulletin does not publish manuscripts covering the snthesis of Gold nanoparticles in the presence of plant extracts or other nature-derived extracts. Gold Bulletin has been published over 40 years as a multidisciplinary journal read by chemists, physicists, engineers, metallurgists, materials scientists, biotechnologists, surface scientists, and nanotechnologists amongst others, both within industry and academia. Gold Bulletin is published in Association with the World Gold Council.
