Rapid Biosynthesis of Silver Nanoparticles By Celtis Tournefortii Lam. Leaf Extract; Investigation of Antimicrobial and Anticancer Activities

Abstract

The usage of metallic nanoparticles are very common. Environmentally friendly approaches in obtaining nanoparticles attract a lot of attention because of their advantages. In this study, an easy and economical biosynthesis of silver nanoparticles (AgNPs) was made with the extract of Celtis tournefortii LAM. leaf. For the characterization of synthesized nanoparticles, Spectrophotometer (UV-vis), Transmission Electron Microscope (TEM), Field Emission Scan Electron Microscopy (FE-SEM), Atomic Power Microscopy (AFM), Electron Disperse X-ray (EDX) Fourier Transformation Infrared Spectroscopy (FT-IR), X-ray Diffraction (XRD), Thermogravimetric and Differential Thermal Analysis (TGA-DTA), Zeta Sizer and Zeta Potential Analysis data were used. As a result of the data analysis, it was determined that the AgNPs had a spherical appearance, an average size distribution of 4.8 nm, had a maximum absorbance at a wavelength of 482.13 nm, a crystal nanosize of 10.95 nm, and a surface charge of-21.6 mV. Inhibition activities of AgNPs on the growth of pathogenic strains were determined by the microdilution method. The results showed that the nanoparticles were effective even at low concentrations. The Minimum Inhibitory Concentration (MIC) value of the tested materials on the growth of the strains was found between 0.03-1.00 mu g mL-1. Anticancer activity of AgNPs was investigated on CaCo-2, U118, Skov3 cancer cell lines and healthy cell line HDF by the MTT method.
