Silver nanoparticles made from Tagetes erecta flower extract using green synthesis: Characterization methods and antibacterial activity

Abstract

Due to its extensive applications in a variety of fields, including electronics, catalysis, chemistry, energy, and medicine, there is a growing commercial demand for nanoparticles. This study uses the Tagetes erecta flower to create and characterise silver nanoparticles. Utilizing UV-Visible spectroscopy, Fourier transform infrared spectroscopy, x-ray differentiation, and TEM examination, the produced nanoparticles were characterised. After 5 hours of incubation, the reaction mixture took on a brownish-gray colour and had an absorbance peak that is typical of Ag nanoparticles at 412 nm. Analysis using transmission electron microscopy (TEM) revealed that the silver nanoparticles were pure, polydispersed, and ranged in size from 10 to 40 nm. A cheap, environmentally friendly, and simple alternative to traditional methods of creating silver nanoparticles is the green synthesis approach. A cheap, environmentally beneficial, and simple alternative to traditional techniques of creating silver nanoparticles is the green synthesis strategy.
