Green Synthesis of ZnO Nanoparticles Using Ficus benghalensis for Visible Light-Driven Photocatalytic Degradation of Crystal Violet and Antibacterial and Antibiofilm Activities.

Crystal Violet (CV) is a vibrant and harmful dye known for its toxicity to aquatic life and potential carcinogenic effects on humans. This study explores the removal of CV through photocatalysis driven by visible light, as well as examining the antibacterial and antibiofilm characteristics of zinc oxide nanoparticles (ZnO NPs) synthesized from the aerial roots of Ficus benghalensis. Various characterization techniques were employed to confirm the optical properties, crystal lattices, and morphology of ZnO NPs.

Characterization and toxicology evaluation of zirconium oxide nanoparticles on the embryonic development of zebrafish, Danio rerio.

Zirconia oxide nanoparticles (ZrONPs) are known to be one of the neutral bioceramic metal compounds that has been widely used for their beneficial applications in many biomedical areas, in dental implants, bone joint replacements, drug delivery vehicles, and in various industrial applications. To study the effects of ZrONPs on zebrafish model, we used early life stages of the zebrafish (Danio rerio) to examine such effects on embryonic development in this species. ZrONPs were synthesized by the sol-gel method, size about 15-20 nm and characterized by SEM, EDX, XRD, FTIR, UV-Vis Spectra.
