摘要：
Pithecellobium dulce leaf extract was used to synthesize gold nanoparticles (AuNPs) for the first time. This bio-synthesized novel material was investigated by UV-visible spectra, high-resolution transmission electron microscopy, powder diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, and energy-dispersive analysis by X-ray. Excellent antibacterial activity was revealed against Staphylococcus aureus and Escherichia coli. Significant antifungal activities by the AuNPs were also demonstrated. The analysis of AuNPs by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay proved 100 % toxic effect and the minimum value of half-maximal inhibitory concentration (IC50) indicates that it is safe to be used as drug in the medical field.
