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.
