ANTIMICROBIAL ACTIVITY OF SILVER NANOPARTICLES FROM SUBSTITUTED AND UNSUBSTITUTED IMIDAZOLIUM IONIC LIQUIDSAbstract
Nanotechnology is an innovative and escalating field that has made its contribution to all spheres of human life. Conventional synthesis of nanoparticles suffers from serious problems like high temperature, poor yield, longer reaction time, and use of toxic and highly sensitive compounds. Green synthesis of nanoparticles is an emerging field which is known to eliminate / minimize the aforementioned drawbacks. In the present investigation, stable silver nanoparticles were synthesized in good yield by chemical reduction of silver nitrate in ionic liquids such as [BMIM] BF4 (IL-1), [BMIM] PF6 (IL-2), [BEMIM] BF4 (IL-3) and [BEMIM] PF6 (IL-4) at room temperature. X-ray diffraction (XRD) and scanning electron microscopy (SEM) have been employed for the characterization of structure and morphology of the synthesized silver nanoparticles. The as synthesized nanoparticles and pure ionic liquids were screened for their anti-microbial activities and it was found that both the pure ILs and silver nanoparticles possess significant antimicrobial activity.
