Title

BIOSYNTHESIS AND CHARACTERIZATION OF ZINC, MAGNESIUM AND TITANIUM NANOPARTICLES: AN ECO-FRIENDLY APPROACH

Pages

  1-10

Abstract

 In the present study, ZINC (Zn), MAGNESIUM (Mg) and TITANIUM (Ti) NANOPARTICLES synthesized using fungus by employing various precursor salts of sulfate salts, nitrate salts, chloride salts and oxide salts. To access the nanoparticle production potential, over a hundreds of fungi were isolated from the soil and tested with precursor salts of the Zn, Mg and Ti. Out of which, only 14 fungal isolates were identified, having potential to reduce metal salt into metal NANOPARTICLES. Upon molecular identification, six were identified as Aspergillus flavus, two each as Aspergillus terreus and Aspergillus tubingensis and one each as Aspergillus niger, Rhizoctonia bataticola, Aspergillus fumigatus, and Aspergillus oryzae. Factors responsible for more production of monodispersed Zn, Mg and Ti NANOPARTICLES were optimized. It was concluded that 0.01 mM precursor salt concentration, 72 h of incubation at pH 5.5 and temperature 28oC resulted smaller NANOPARTICLES obtained. The biosynthesized functional Zn and Ti NANOPARTICLES can be stored up to 90 days and Mg NANOPARTICLES up to 105 days in its nanoform. Bio-transformed products were analyzed using valid characterization technique i.e. dynamic light scattering, transmission electron microscopy, atomic force microscopy, energy dispersive X-ray spectroscopy to confirm size, shape, surface morphology and elemental composition. It was found that the average size of developed nano Zn was 8.2 nm, with surface charge of-5.70 mV and 98% particles were of Zn metal only. Similarly, the average size of Mg NANOPARTICLES was 6.4 nm with surface charge of-6.66 and 97.4% Mg metal yield, whereas, Ti NANOPARTICLES size were found in the ranges between 1.5 and 30 nm with surface charge of-6.25 mV and 98.6% Ti metal yield.
