Thiol oxidation翻译
WebA new surface oxidation mechanism that enhances the luminescence of Au nanoclusters is discovered in Au nanoclusters synthesized with disulfide lipoic acid. The quantum efficiency increased from 1 to 2% up to 10% upon the sulfur oxidation at the Au–ligand interface. Relatively low quantum efficiency has been a bottleneck barrier to exploit the appealing … WebOxidative stress has been recognized as a contributing factor in the toxicity of a large number of developmental toxicants. Traditional definitions of oxidative stress state that a shift in the balance between reduced and oxidized biomolecules within cells, in favor of the latter, result in changes that are deleterious to vital cell functions ...
