Green synthesis of silver/montmorillonite/ chitosan bionanocomposites using the UV irradiation method and evaluation of antibacterial activity.

In this study, silver nanoparticles (Ag-NPs) were synthesized using a green physical synthetic route into the lamellar space of montmorillonite (MMT)/chitosan (Cts) utilizing the ultraviolet (UV) irradiation reduction method in the absence of any reducing agent or heat treatment. Cts, MMT, and AgNO...
