Abstract
leaf extract as a reducing agent. The synthesis of AgNPs was confirmed using UV-vis spectroscopy, and the properties of AgNPs were characterized using Transmission Electron Microscope, Fourier Infrared Spectrometer, X-ray diffraction, Thermogravimetric Analysis, and Zeta potential. The results showed that the AgNPs exhibited a characteristic absorption peak at 430 nm, their diameter ranged from 4 nm to 52 nm, and C, O, and Cl elements, which might represent flavonoids and phenolic components absorbed on the surface of AgNPs. The zeta potential of AgNPs was found to be -30.5 mV, which indicates repulsion among AgNPs and they have good dispersion stability. AgNPs have been found to suppress the tyrosinase activity both in mushroom tyrosinase and A375 cells, as well as diminish ROS formation in HaCat cells. According to this study, AgNPs is a novel material that can enhance skin health by preventing melanin development.
