Bio-Synthesis and Characterization of CS–Ag Nano Hydrogel for Antibacterial Application

An environmental technique of herbal mediated blend of Ag nanoparticles is a substantial stage in the ground of nanotechnology. Chitosan (CS) is a polymer which is biocompatible and antibacterial. In this work, we have synthesized CS–Ag Nano hydrogel which is form with chitosan-based hydrogel merged in the herbal synthesized Ag nanoparticles. These green synthesized Ag-nanoparticles made from Polygonum bistorta plant leaves and described with the assistance of UV-vis spectrophotometer, and Dynamic Light Scattering (DLS). In this work our main focus to synthesized CS–Ag Nano hydrogel. These hydrogel was described by Fourier transform infrared (FTIR) spectroscopic method, X-ray diffraction (XRD) method, and contact angle. Nanoparticle size distribution was within 1 to 100 nm by DLS and the optimum wavelength was noted in 400 to 450 nm by UV-vis spectroscopic readings. A good antibacterial behavior has been displayed by these synthesized CS–Ag Nano hydrogel films against both E. coli (gram –ve) and S. aureus (gram +ve) with the maximum 7 mm inhibition zone.
