摘要: ABSTRACTCopper nanoparticles (CuNPs) were synthesized by reducing a copper sulfate solution using the aqueous extract of Ferula macrocolea flowers. The optimum conditions 0.01 M CuSo4.5H2O volume ratio 1.5, pH 12, temperature 80°C and incubation time 2 h. ultraviolet–visible absorption spectra confirmed formation CuNPs with characteristic peak at 576 nm. X-ray diffraction scanning electron microscope analysis revealed spherical-shaped an average size 22.3 nm ranged between 11 33 nm. Energy-dispersive fluorescence showed in region. fourier transform infrared spectroscopy capping compounds contained F. macrocolea flowers extract. demonstrated activity against Staphylococcus aureus, followed Bacillus cereus, Escherichia coli Klebsiella pneumonia. Cytotoxicity assay indicated no decrease viability normal human lymphocytes up t...
