Green synthesis of silver nanoparticles (AgNPs) using the silk sericin (SS) solution by in situ reduction at room temperature is reported. The effect of pH on the reduction reaction is studied by UV-Vis spectroscopy. The structure of the sericin-based silver nanoparticles is characterized by TEM. According to the TEM images, the average size of the silver nanoparticles is about 16 nm. The silver nanoparticles are highly dispersed and stable in silk sericin solution for monthes.

Semi-IPN hydrogels in which silk sericin (SS) chains were physically dispersed throughout dextran (Dex) gel networks were synthesized. Highly stable distributed silver nanoparticles have been prepared using these semi-IPN hydrogels as a carrier via in situ reduction of silver nitrate without the addition of any reducing agent. The resultant semi-IPN hydrogel-silver nanocomposites were characterized by X-ray diffraction (XRD). And the swelling behavior of the hydrogles was also studied.

The aim of this study was to perform green synthesis of silver nanoparticles (AgNPs) from the leaf extract of Desmostachya bipinnata (Dharba), a medicinally important herb which is widely used across India. Synthesized AgNPs were analyzed by UV-Visible spectroscopy, X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), and energy dispersive X-ray spectroscopy (EDAX). The results have confirmed that green synthesis of AgNPs leads to the fabrication of sphere-shaped particles with a diameter of 53 nm. Furthermore, these AgNPs were subjected to antioxidant and antimicrobial studies against gram-negative and gram-positive bacteria, where AgNPs at a concentration of 20 mg/mL showed highest zone of inhibition. Synthesized AgNPs were evaluated for their antioxidant activity by 1, 1-diphenyl-2-picryl hydrazyl radical (DPPH), H2O2, and superoxide inhibiting assays; increasing concentration has showed increase in scavenging ability. Cell toxicity was assessed on HepG2 cell lines, and synthesized nanoparticles at a concentration of 128 μg/mL produced significant reduction in viability of Hep cells ( P < .05). The availability of Dharba throughout the year and the eco-friendly approach in the synthesis of AgNPs coupled with bioactivity has demonstrated its potential as a novel biomaterial which can be used for various biomedical applications.
