Synthesis of Silver/Zinc@Lignin nanoparticles using peanut shells: photocatalytic and biological activity.
In this paper, zinc and silver-doped lignin nanoparticles (Ag/Zn@Lignin nanoparticles) were synthesized in two steps using peanut outer shells. The optical properties of NPs were analyzed through UV-Vis and PL measurements, while X-ray analysis approved their crystal structure. The surface characteristics and chemical composition of NPs were identified using FTIR analysis. TEM images of Ag/Zn@Lignin nanoparticles showed spherical morphology with an average size of about 22.71 nm. The antibacterial activity of Ag/Zn@Lignin nanoparticles was assessed against gram-negative and gram-positive bacteria, and the results exhibited strong antibacterial properties against the pathogenic strain compared to the standard. The MTT test results indicated that Ag/Zn@Lignin nanoparticles were more sensitive against cancer cells (Huh-7) in comparison with normal cells (L929), and IC50 values were reported as 122.9 and 389 µg/mL in order. Also, photocatalytic effects displayed the high ability of Ag/Zn@Lignin nanoparticles to degrade organic pigments such as Rhodamine B (98.8%, RhB) and Methylene blue (98.8%, MB) under UV light.
期刊介绍：
AMB Express is a high quality journal that brings together research in the area of Applied and Industrial Microbiology with a particular interest in ''White Biotechnology'' and ''Red Biotechnology''. The emphasis is on processes employing microorganisms, eukaryotic cell cultures or enzymes for the biosynthesis, transformation and degradation of compounds. This includes fine and bulk chemicals, polymeric compounds and enzymes or other proteins. Downstream processes are also considered. Integrated processes combining biochemical and chemical processes are also published.
