| Popis: | A facile synthesis method of gold nanoparticles (AuNPs) utilizing Lantana camara flower extract (LFE) using visible light illumination towards the bio-reduction system has been conducted. The systematic characterizations of AuNPs were employed using transmission electron microscopy, X-ray powder diffraction, scanning electron microscopy, and X-ray photoelectron spectroscopy. The nanoparticles having a particle size of ranging 4.8–25 nm were obtained with dependence on the LFE concentration of the extract and time of light irradiation. The antibacterial activity of AuNPs was evaluated against Escherichia coli, Staphylococcus aureus, Propionibacterium acnes, and Pseudomonas aeruginosa, and the photocatalytic activity was examined in methylene blue photooxidation. The overall results point to a promising photochemical synthesis of AuNPs utilizing plant extract and the potential activities of synthesized nanoparticles as antibacterial agents and photocatalysts. |
