Noble metal nanoparticles, such as gold and silver, are well known in the research field of catalysis and biomedical applications. For example, gold and silver nanoparticles can be good catalysts for various chemical transformations, such as hydrogenation and oxidation. They can also be used for bioimaging, and as drug carriers and radiosensitizers in cancer therapy due to their optical properties and biocompatibility. Silver nanoparticles have been widely researched and used in commercial products for their antimicrobial activity towards a broad spectrum of microorganisms.
