Abstract:
In recent science Nanotechnology is a burning field for the researchers. Nanotechnology Deals with the Nanoparticles having a size of 1-100 nm in one dimension used significantly concerning medical chemistry, atomic physics, and all other known fields. The present study reports an eco-friendly, cost efficient, rapid and easy method for synthesis of silver nanoparticles using banana peel extract (BPE) as a reducing and capping agent. The different factor affecting silver reduction was investigated. The conditions were silver nitrate (1.75 mM), BPE (20.4 mg dry weight), pH (4.5) and incubation time (72 h). BPE can reduces silver ions into silver nanoparticles within 5 min after heating the reaction mixture (40-100C) as indicated by the developed reddish brown color. The biosynthetical NPs were characterized using UV, FTIR. The UV-Vis spectrum of silver nanoparticles revealed a characteristic surface plasmon resonance (SPR) peak at 420,345,545 nm. Silver nanoparticles were characterized. . Fourier transform infrared spectroscopy affirmed the role of BPE as a reducing and capping agent of silver ions. Silver nanoparticles showed effective antimicrobial activity against representative pathogens of bacteria and used as antifungal agents. The synthesized nanoparticles showed synergistic effect with levofloxacin antibiotic, the antimicrobial activity and show plant growth promoting activity.
