In this study, gold nanoparticles (CF-AuNPs) were efficiently prepared from aqueous extracts of ripened Capuli (
Prunus serotina
Ehrh. var. Capuli) fruit by reduction of Au
3+
and characterized by a variety of instrumental analyses. A noticeable change in color to ruby red/purple was observed during the formation and stabilization of CF-AuNPs. The UV–Vis spectroscopy has proven the characteristic absorption peaks λ
max
544 nm and 934 nm of CF-AuNPs. The biosynthesized CF-AuNPs were spherical and triangular shape confirmed through TEM analysis. The average size of the different CF-AuNPs observed during the DLS and TEM analysis ranged from 30 to 400 nm. The partial crystallinity of CF-AuNPs and their surface binded with phytochemicals is evident from the XRD patterns. Furthermore, synthesized CF-AuNPs have also been applied for antioxidant and photocatalytic applications. This work covers the fundamental principals of green chemistry and joins hands for environmental protection through nanoscience.
