Shora (Capparis petiolaris) fruit mediated green synthesis and application of silver nanoparticles

Abstract

This report describes a rapid, facile and an ecofriendly synthesis of silver nanoparticles (AgNps) using fruit extracts of Shora (Capparis petiolaris) and further as-synthesized AgNps were characterized by UV-vis spectroscopy, transmission electron microscopy (TEM), and X-ray diffraction (XRD) techniques. The effects of various other parameters such as pH, concentration of fruit extract, time, and change of light sources are studied. Analytical characterizations revealed that the sunlight-induced AgNps appeared at λmax=423 nm, had a spherical shape and varied in the range of 10–30 nm. Furthermore, AgNps showed moderate antioxidant activity against 2, 2-diphenyl-1-picrylhydrazyl (DPPH·) (38.98%, 0.125 mm) and photocatalytic activity for the degradation of methylene blue (MB) (>58%, 240 min). The results indicated that as-synthesized AgNps could be used in future engineering and biomedical products.
