Biomimetic synthesis of nanogold using Bidens tripartitus extract and evalution of their antimicrobial and catalytic activities
Renata Dobrucka , Jolanta Długaszewska
AbstractThis work presents the biomimetic method for synthesizing nanogold using Bidens tripartitus extract. The obtained Au nanoparticles were characterized by UV–vis spectrophotometry (UV-VIS), Transmission electron microscopy (TEM), Scanning electron microscopy (SEM) with EDS profile and Atomic Force Microscopy (AFM). The techniques used in the study confirmed the presence of Au nanoparticles with the size of about 20 nm. In order to assess the presence of biologically active compounds, Fourier transform infrared spectroscopy (FTIR) was used. The synthesized gold nanoparticles possess excellent activity against different bacteria, both Gram-positive (S. aureus) and Gram-negative (E. coli, P. aeruginosa), and fungi (yeast: C. albicans; molds: A. niger; dermatophites: T. rubrum). The study of the catalytic properties showed the excellent activity of nanogold in the reduction of organic dyes: methylene blue (MB) and methyl orange (MO).
