Biogenic Synthesis of Silver Nanoparticles for Nanosensor-Based Mercury Detection.

The production of nanoparticles via green methods is a developing study domain due to potential environmental applications. The green synthesis method is very easy, less toxic and eco-friendly when compared to the chemical synthesis method. This study addresses the silver nanoparticle synthesis utilizing the Acorus calamus leaf extract, which was then employed for environmental applications.

Hydrothermal synthesis and characterization of the antimony-tin oxide nanomaterial and its application as a high-performance asymmetric supercapacitor, photocatalyst, and antibacterial agent.

We have synthesized antimony-tin oxide (ATO) nanoparticles chemically for use in antibacterial, photocatalytic, and supercapacitor applications. The XRD pattern reveals the hexagonal structure, while the FTIR spectra validate the functional groups. The agglomerated nanostructures, which are 40-50 nm thick and 100 nm long, are shown in the SEM images as having spherical, cube, square, and rod form morphologies.

Dyeing of cotton fabric materials with biogenic gold nanoparticles.

The present work aimed at synthesizing gold nanoparticles in a biological method employing fruit peel waste dumped in the environment. The peels of Garcinia mangostana (Mangostan), were collected from the nearby tourist spot during the season. The collected fruit peels were washed, dried, powder and extracted by using boiling water and acetone.

Degradation of methylene blue using biologically synthesized silver nanoparticles.

Nowadays plant mediated synthesis of nanoparticles has great interest and achievement due to its eco-benign and low time consuming properties. In this study silver nanoparticles were successfully synthesized by using Morinda tinctoria leaf extract under different pH. The aqueous leaf extract was added to silver nitrate solution; the color of the reaction medium was changed from pale yellow to brown and that indicates reduction of silver ions to silver nanoparticles.
