Synthesis Of Selenium Nanoparticles Using Binary Mixture Extracts Of Moringa Oleifera And Solanum Lycopersicum

Abstract

Nanoparticles have been developed through green synthesis as an alternative to the conventional chemical synthesis as sustainable and environmentally friendly. The current work involved the production of selenium nanoparticles (SeNPs) through the utilization of a binary mixture of plant extracts, which was then separated by utilization of a binary mixture of plant extracts of the Moringa oleifera and Solanum lycopersicum. The plant material was extracted at a ratio of 1:10 (w/v) of the plant material to the solvent to extract the ethanolic extracts. The two extracts were mixed in equal proportions to produce a combined phytochemical system which will be a reducing as well as a stabilizing agent. The extract solution was reacted with a drop of sodium selenite (Na₂SeO₃) in aqueous solution under controlled conditions. The mixture reactor was stirred on magnetic stirrer at 45-55 Celsius and 1500 to 2500 rpm per hour within one hour. The formation of the observable shift in color of the extract as it shifted to become greenish initially followed by reddish-orange suspension was a sign of the production of selenium nanoparticles. UV-Visible spectroscopic analysis of the presence of nano-particle was performed and total spectral scan depicted characteristic absorption at the wavelength of 250-270nm. The spectral analysis showed that the extract of the binary plant had a broad spectrum of absorption with a narrow and stronger spectrum of absorption in the synthesized SeNPs which means that the selenium ions were successful reduced and the nanoscale particle was formed. As demonstrated in this paper, the green synthesis of selenium nanoparticles by the participation of a binary phytochemical system of Moringa oleifera and Solanum lycopersicum is possible. This plan denotes that plant-based binary extract systems have promising potential in the environmentally friendly synthesis of nanomaterials.
