Green synthesis of silver nano particles using Dracaena Trifasciata plant extract and comparison of fatty acids and amides capping agents

Abstract

Green synthesis of NPs evades many of the deleterious aspects by permitting the synthesis of nanoparticles at relatively low temperatures, pH and pressure, all at a significantly lower cost and short time. A bottom-up approach is used for the synthesis of silver nanoparticles formed due to the reduction of silver ions because of the existence of the phytochemicals contained in the Dracaena Trifasciata plant extract, which is primarily used for the study of green synthesis. X-ray diffraction, scanning electron microscope, Uv-Vis spectroscopy, and Fast Fourier Infrared spectroscopy characteristic techniques are used to analyze the nature of the silver nanoparticles formed by the green synthesis method. To prevent the over-growth of silver nanoparticles and avoid their aggregation, one fatty acids based and one amides based capping agent has been used for the comparison purpose for the preservation of the silver nanoparticles in term of shape, size and coagulation, which is a novel study. Amides interacted with the silver nanoparticles via electrostatic interactions which result in strong stabilization compared to the fatty acids which make van der wall interactions with the surface of the nanoparticles but for bio compatibility and environmentally friendly applications, fatty acid based capping agent can be preferred as these NPs are also suitable for the use in the field of medicine and pharmaceuticals.
