GREEN NANOPARTICLES FROM BUTEA MONOSPERMA AND EVALUATION OF THEIR ANTIMICROBIAL ACTIVITY

Biosynthesis (Green synthesis) of nanoparticles by plant extract is currently under exploitation. The development of such biological experimental processes for the preparation of AgNPs is evolved into an important branch of Nanotechnology. The present study reveals preparation of silver nanoparticles (AgNPs) utilizing bark extract of Butea monosperma and evaluation of its antimicrobial activities against various microorganisms. Butea monosperma showed strong potential for synthesis of silver nanoparticles, by rapid reduction of silver ions (Ag+ to Ag) and the formed AgNPs demonstrated a strong potential against Escherichia coli, Bacillus subtilis, Pseudomonas aeruginosa and Streptococcus pneumonea. The results were compared with the effects of antibiotics, and were found to be more potent than antibiotics. It was also recorded that small concentration of nanoparticles strongly inhibited the microbial growth rate.
