Abstract
A rapid, green, and easy strategy for the Biosynthesis of Zinc oxide
Nanoparticles using the leaf of Memecylon talbotianum D. Brandis
(Melastomataceae). it is non-hazardous compared to physical and chemical
synthesis methods.it is a cost-effective and eco-friendly synthesis. The
current study deliberates to focus on the green synthesis of Zinc oxide
nanoparticles by zinc nitrate and utilizes the bio components of plant leaf
extract of M. talbotianum. Zinc oxide is an inorganic nanoparticle the
crystals were synthesized in an eco-friendly way. Zinc oxide has a broad
spectrum of applications. The structures of synthesized nanoparticles were
characterized by using UV-visible absorbance spectroscopy (UV),
Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), Energy
dispersive X-ray (EDX) and scanning electron microscope (SEM) to determine the
phase and morphology of nanoparticles (NPs).In UV-visible spectroscopic
analysis portrayed surface Plasmon resonance at 365nm, of synthesized ZnONps,
and FTIR suggested the presence of Alcohol, Aldehyde, carbon dioxide,
Isothiocyanate, Carboxylic acid, Alkene, Nitro compounds, Alkane, Alkene.
Synthesized particles were a flower in shape, and In XRD 2 q
values ranging from 27.3° to 75.32° values, Elemental Detection by X-Ray
Diffraction method (EDX) analysis shows the mass percentage of Zinc and Oxide
are 70.43% and 21.72% respectively, and provision with larvicidal activity from
Culex species shown LC50 values for Methanol, Pet ether, and Zn nanoparticles
showing 205.11, 307.6, 123.82, 229.08, 98.1, 21.72 mg/L to know their potential
as a promising tool in vector control strategies for combining mosquito-borne
diseases.
