Abstract
Gold and silver nanoparticles (Au/AgNPs) are widely used in analytical chemistry, and their intense colors have inspired artists and fascinated scientists.This review describes the absorption and Rayleigh-scattering effects of the surface-plasmon resonance (SPR) of Au/AgNPs. Specifically, the color associated with Au/AgNPs is utilized for immunoassay and aptamer assays. SPR-Rayleigh scattering is used for nanoanalysis, when combined with immune, aptamer and nanocatalysis reactions.
► We review gold/silver-SPR absorption and SPR-Rayleigh-scattering effects. ► SPR absorption has been utilized for immunoassay and aptamer assay. ► SPR-Rayleigh scattering has been used for immune, aptamer and nanocatalytic analysis.
