Synthesis of silver nanoparticles (AgNPs) from cinnamon against bacterial pathogens

Nanotechnology can be useful in diagnostic techniques, drug delivery, sunscreens, antimicrobial sanitizer and a friendly manufacturing process that reduce waste products. Development of Green Nanotechnology is generating interest of researchers towards eco-friendly biosynthesis of nanoparticles. In the research study silver nanoparticles were synthesized from aqueous silver nitrate (1 mM) through a simple and eco-friendly method using cinnamon as reductant and stabilizer. The aqueous silver ions when exposed to leaf broth were reduced and resulted in the green synthesis of silver nanoparticles ranges from 20 nm to 30 nm. The bio reduced silver nanoparticles were characterized by UV-Vis spectrophotometer, X ray diffraction, FESEM with EDAX and Fourier transform infra red (FTIR) spectroscopy. The FTIR study was carried out to recognize the possible biomolecules responsible for proficient stabilization of silver nanoparticles and their antimicrobial activity was screened against both gram positive, gram-negative microorganisms. The method can be used for rapid and eco-friendly biosynthesis of stable silver nanoparticles of size range from 20 to 30 nm possessing antimicrobial activity suggesting their possible application in the field of medicine.
