Biogenic Synthesis, Characterization, and In Vitro Biological Evaluation of Silver Nanoparticles Using Cleome brachycarpa

Abstract

The therapeutical attributes of silver nanoparticles (Ag-NPs) in both conditions (in vitro and in vivo) have been investigated using different plants. This study focused on the green chemistry approach that was employed to optimize the synthesis of silver nanoparticles (AgNPs) using Cleome brachycarpa aqueous extract as a reducing and stabilizing agent. The characterization of obtained CB-AgNPs was undertaken using UV-visible spectroscopy, Atomic-force microscopy (AFM), Fourier-Transform Infrared Spectroscopy (FTIR), scanning electron microscopy (SEM), and Energy-Dispersive X-ray (EDX) analysis. Results suggest that CB-AgNPs synthesized via stirring produced small-sized particles with more even distribution. The synthesized silver nanoparticles were spherical with a 20 to 80 nm size range. In vitro studies were used to analyze antioxidant, antidiabetic, and cytotoxic potential under different conditions. The results also indicated that CB-AgNPs may have significant potential as an antidiabetic in low concentrations, but also exhibited potential antioxidant activity at different concentrations. Moreover, the anticancer activity against the breast cell line (MCF-7) with IC50 reached up to 18 μg/mL. These results suggest that green synthesized silver nanoparticles provide a promising phytomedicine for the management of diabetes and cancer therapeutics.

Biosynthesis of Silver Nanoparticles Using Tabernaemontana ventricosa Extracts

“…Nanoparticles (NPs) are often described as extremely tiny materials that exhibit nanoscale dimensions ranging from 1 to 100 nm [1,[4][5][6]. The specific features of AgNPs such as their large surface-area-to-volume ratio, size, shape, and morphology have optimized their activity in a variety of applications, which include health, medicine, chemistry, food, textiles, agricultural sectors, and nanofluids (energy harvesting and heat transfer enhancing) [6][7][8][9][10][11]. Furthermore, recently, silver nanoparticles have been frequently used as antibacterial materials against disease-causing microbes [12].…”
