Agricultural waste Annona squamosa peel extract: Biosynthesis of silver nanoparticles

Development of reliable and eco-friendly process for the synthesis of metallic nanoparticles is an important step in the field of application of nanotechnology. We have developed modern method by using agriculture waste to synthesize silver nanoparticles by employing an aqueous peel extract of Annona squamosa in AgNO3. Controlled growth of silver nanoparticles was formed in 4 h at room temperature (25 °C) and 60 °C. AgNPs were irregular spherical in shape and the average particle size was about 35 ± 5 nm and it is consistent with particle size obtained by XRD Scherer equation.

The present study indicates that silver nanoparticles can be achieved even through agricultural waste peel extract.Figure optionsDownload as PowerPoint slideHighlights
