Antibacterial Activity of Biofabricated Molybdenum Nanoparticles

The study is the first report on Molybdenum nanoparticles synthesis using wood apple shell extract. Microorganisms, fungus, enzymes and plants are used for biosynthesis of nanoparticle, which acts as ecofriendly alternative to chemical and physical methods. Molybdenum nanoparticles or nanopowder are black high surface area particles. The Molybdenum nanoparticle was synthesised using Wood Apple shell extract through calcination process. The characterization of synthesized Molybdenum nanoparticles was done using UV Visible spectroscopy, Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscopy (SEM). The UV-Visible spectroscopic analysis showed maximum absorption peak at 260 nm. The observed spectrum of FTIR analysis shows distinct bands at 2735.29 cm⁻¹, 2396.44 cm⁻¹, 1763.99 cm⁻¹, 1383.79 cm⁻¹, 875.15 cm⁻¹ and 825.74 cm⁻¹. In SEM study the shape of Molybdenum nanoparticles was found to be spherical. The antibacterial activity of Molybdenum nanoparticles is studied against Gram positive and Gram negative broth cultures and highest inhibitory effect was observed for Gram negative bacteria Proteus mirabilis and Klebsiella pneumonia. These findings confirm that the Molybdenum nanoparticle has complimentary potential to treat various bacterial infections like Urinary tract infection, Blood stream infections and Meningitis.
