Metal nanoparticles, particularly gold and silver, exhibit strong localized surface plasmon resonance (LSPR) in the visible and near-infrared regions. This property arises from the collective ...

Gold nanoparticles (AuNPs) are nanoscale particles of gold, typically ranging in size from 1 to 100 nanometers (nm). These nanoparticles exhibit unique physical, chemical, and optical properties that ...

The effects of varying gold precursor concentrations and immersion times on nanoparticle formation and ... the localized surface plasmon resonance (LSPR) of the AuNPs. This behavior demonstrated ...
