Biosynthesis, characterization, and investigation of antimicrobial and cytotoxic activities of silver nanoparticles using peel aqueous extract.

Metallic nanoparticle biosynthesis is thought to offer opportunities for a wide range of biological uses. The green process of turning biological waste into utilizable products gaining attention due to its economical and eco-friendly approach in recent years. This study reported the ability of (ST) peel extract to the green synthesis of non-toxic, stable, small-sized silver nanoparticles without any toxic reducing agent utilizing the phytochemical components present in its structure.

The Investigation of the Chemical Composition and Applicability of Gold Nanoparticles Synthesized with (Almond) Leaf Aqueous Extract as Antimicrobial and Anticancer Agents.

The current work's main objective was to determine the chemical composition of (AC) leaf extract and examine the antibacterial and cytotoxic properties of biosynthesized gold nanoparticles (AuNPs). The chemical composition of AC leaf extract was determined using LC-ESI/MS/MS to detect compounds that may be responsible for the reducing, stabilizing, and capping steps in the synthesis of nanoparticles and their biological activities. The AC-AuNPs were spherical, with a particle size lower than 100 nm and a face-centered cubic structure.
