  • Green Synthesis of Silver Nanoparticles using CMC Powder and Investigation of Its Antibacterial Activity
    Publication number: 20230226607
    Abstract: The present invention is directed to a method to produce silver nanoparticles. The method includes the steps of dropwise addition of silver nitrate solution to a carboxymethyl cellulose solution (1%) while stirring. The solution is subjected to ultrasonic irradiation for 30 minutes. The first indication of silver nanoparticles being synthesized can be change in the color of the solution to yellowish-brown after Ultrasonication. The solution can thereafter be subjected to microwave irradiations. After the predetermined duration, the produced silver nanoparticles can be separated from the solution. The nanoparticles can be washed and freeze dried.
