Synthesis Of Silver Nanoparticles Using Essential Oils And Preliminrary Examination Of Its Antibacterial Acitivity
(Nguyen Tat Thanh University, Faculty Of Enviromental And Food Engineering, 2024) Phan, Nguyen Yen Nhi; Trieu, Quoc An
In this study, silver nanoparticles (AgNPs) were synthesized green chemically from diluted acetone essential oil. The influencing parameters when synthesizing such as the effect of essential oils, the effect of pH, the effect of the concentration of the essential oil, the effect of the concentration of silver nitrate, the effect of temperature, the antibacterial ability. Structural features of biosynthesized AgNPs were determined by color observation, methods such as UV-Vis absorption spectroscopy, Dynamic Light Scattering and Transmission Electron Microscopy, which showed the spherical shape of AgNPs with the size of 28 – 80 nm. In addition, there is antibacterial activity of the suspension system of AgNPs as against gram-negative and gram-positive bacteria such as Staphylococcus Aureus (S.aureus), E.coli, Bacillus cereus.
