Evaluation of antimicrobial potential of silver nanoparticles synthesized by curry (Murraya koenigii) against pathogenic bacteria

S Ijjatdar, S Gaherwal, M M Prakash

This study was aimed to synthesizing AgNP from Curry (Murrayakoenigii), plant leaf and investigates its antibacterial activity against different bacteria. AgNP was synthesized by Herbal method. The characterization of nanoparticles was done by XRD, FTIR and Uv-spectroscopy method. Antibacterial activity was determined by disc diffusion, well diffusion method and MIC. The size of biosynthesized silver nanoparticles was found to be within the range of 20-60 nm. To identify the compounds for the reaction of silver ions, the functional groups present in plant extract were investigated by FTIR. XRD analysis confirms the nanocrystalline phase of silver with FCC crystal structure. The formation of silver nanoparticles in dispersion was monitored through the analysis of absorbance spectra by UV-Visible spectrophotometer at different stage during the process of synthesis. The result showed that all three leaves play an importance role in the reduction and stabilization of silver to silver nanoparticles. This green synthesis method is alternative to chemical methods, since it is cheap, pollutant free and eco-friendly. Thus the obtained AgNPs, demonstrated remarkable antibacterial activity against three human pathogenic bacteris when used in combination with commercially available antibiotics. AgNPs have become an important approach for applications in nanobiotechnology in the development of antibiotic treatment of different bacterial infections.
