Featured article: Green synthesis of silver nanoparticles from Tectona grandis seeds extract: characterization and mechanism of antimicrobial action on different microorganisms
Nanotechnology is an emerging field with an interdisciplinary research. It deals with tailoring of particles in the range of 1-100 nm to attain unique properties from their bulk counterpart. Nanoparticles can be synthesized by various means. Chemically synthesized nanoparticles utilize toxic chemicals as reducing agents, which makes it a not so favored method of synthesis. Therefore, green synthesis came into light which makes use of a reducing biological agent to reduce metals to nanoparticles. Repeated and improper devouring of antibiotics to combat infectious diseases leads to drug or even multi-drug resistant strains, which pose a significant threat to society. Silver nanoparticles seem to be the savior due to their antimicrobial activity against various pathogens. In this study Tectona grandis seeds extract is utilized to reduce silver nitrate solution to silver nanoparticles. The synthesized nanoparticles were then characterized and checked for their antimicrobial activity and their mode of action.
