Abstract

Green syntheses of silver nanoparticles have fascinated currently and simple method instead of physical and chemical approaches. In the present study, bioengineered nanoparticles were synthesized using fresh leaves of Ipomoea pes-tigridis. Synthesized nanoparticles were characterized and confirmed by UV Spectrophotometer, followed by EDX, SEM, XRD and FTIR. The nanoparticle size and morphology was confirmed through scanning electron microscope. The resonant oscillation of conduction of electrons with the sample was observed by UV spectra and obtained the peak 440nm. The energy dispersive X-ray analysis has given a strong signal in the silver region which confirmed the presence of elemental silver in the sample. The functional groups present in I. pes-tigridis are responsible for the synthesis of silver nanoparticles were confirmed through FTIR. Further, the synthesized nanoparticles showed high efficiency against drug resistant microbes in the laboratory.
