MICROWAVE-ASSISTED In-situ GENERATED COTTON/SILVER NANOPARTICLES COMPOSITE BY USING AN AQUEOUS EXTRACT OF Acacia Lignin BARK

In general, silver has been recognized as an antimicrobial agent and helpful for the treatment of burns, wounds, and various infections. Now a day silver nanoparticles production in eco friend method is required. Here in, we report a novel method of silver nanoparticles in situ to generate a cotton matrix using Acacia lignin bark aqueous extract as a reducing agent and stabilizer. The silver nanoparticles were in situ generated by combining an Acacia lignin bark extract, cotton fabric, and aq.AgNO3 in one pot, irradiated under microwave for five minutes. The silver nanoparticles (AgNP’s) formed as film inside and outside of the cotton as a matrix was characterized by TEM, FTIR, UV, and EDX spectroscopic techniques. These bio-renewable films show good antibacterial activity and can be used for the bandage, and packing material for medical purposes.
