In vitro and In vivo toxicity assessment of phytofabricated ZnO nanoparticles showing bacteriostatic effect and larvicidal efficacy against Culex quinquefasciatus

Publication date: Available online 30 January 2019Source: Journal of Photochemistry and Photobiology B: BiologyAuthor(s): Mariappan Yazhiniprabha, Baskaralingam Vaseeharan, Avinash Sonawane, Ananyaashree BeheraAbstractMurraya koenigii berry extract based zinc oxide nanoparticles (Mk-ZnO NPs) were synthesized by simple co-precipitation method and examined for bacteriostatic and larvicidal efficiency. Synthesized Mk-ZnO NPs were characterized by UV–Vis spectroscopy at 336 nm. X-Ray diffraction (XRD) showed crystalline nature as hexagonal. Fourier transform infrared spectroscopy (FTIR) spectrum exhibited strong peak at 3442.80 cm−1. Field emission scanning electron microscopy (FE-SEM) showed hexagonal shape of the particle. Transmission electron microscopy (TEM) measured 10–15 nm ...
