In-Situ Biofabrication of Silver Nanoparticles in Natural Fiber Using Extract with Their Antibacterial and Catalytic Dye Reduction Properties.

It is believed of great interest to incorporate silver nanoparticles (Ag-NPs) into stable supported materials using biological methods to control the adverse properties of nanoscale particles. In this study, in-situ biofabrication of Ag-NPs using aqueous extract in () fiber as supporting material was used in which, the extract acted as both reducing and stabilizing agents to incorporate Ag-NPs in the fiber. The properties of Ag-NPs incorporated in the fiber (/Ag-NPs) were characterized using UV-visible spectroscopy (UV-vis), X-ray Diffraction (XRD), Field Emission Transmission Electron Microscope (FETEM), Scanning Electron Microscope (Scanning Electron Microscope (SEM), Energy Dispersive X-ray (EDX), Brunauer-Emmett-Teller (BET), Thermogravimetric (TGA) and Fourier Transform Infrared (FTIR) analyses. The average size of Ag-NPs measured using FETEM image was 4.74 nm spherical in shape. The /Ag-NPs was easily separated after application, and could control the release of Ag-NPs to the environment due to its strong attachment in fiber. The /Ag-NPs exposed good qualitative and quantitative antibacterial activities against (ATCC 25923), (ATCC 29212), (ATCC 25922) and (ATCC 33420). The dye catalytic properties of /Ag-NPs revealed the dye reduction time in which it was completed within 4 min for 20 mg/L rhodamine B and 20 min for 20 mg/L methylene blue dye, respectively. Based on the results, it is evident that /Ag-NPs are potentially promising to be applied in wound healing, textile, wastewater treatment, food packaging, labeling and biomedical fields.
