New Method to Form Colloidal Gold: Spontaneous Transformation from Nanoporous Anodic Gold Oxide Film into Gold Nanoparticles in Pure Water
Gold nanoparticles (Au NPs) exhibit strong localized surface plasmon resonance (LSPR) and have applications in biosensing, optical devices, and conductive materials. The conventional chemical synthesis of Au NPs relies on the dissolution of gold salts such as HAuCl4 and reductants followed by the reduction of gold io...
