Annona squamosa seeds capped calcium oxide nano particles - anti-microbial, antioxidant, anti-ulcer analysis

Abstract

Calcium Oxide (CaO) is the best replica of logically plentiful earth metal oxides. CaO nanoparticles include sphere-shaped or faceted elevated surface area and magnetic nanostructured particles. The current study give the information regarding booming synthesis of calcium oxide nanoparticles using calcium chloride as precursor and Annona squamosa seed extract as capping agent. The main goal of using a biological approach to synthesize CaO NPs is to reduce the use of dangerous chemicals in the process, which will be more economical and environmentally friendly. This is the initial time seeds have been utilised for green nanoparticle deposition. The synthesized powder was golden yellow colour. The obtained CaO NPs have been characterized by X-ray diffraction, scanning electron microscope, ultra violet visible spectroscopy, Fourier transform infra-red, dynamic light scattering studies. The synthesized samples are applied for phytochemical screening, anti-bacterial, anti-fungal, antioxidant and anti-ulcer applications.
