چکیده
|
Sulfur nanoparticles (s-nps) were prepared in this work by precipitation method using sodium thiosulphate and tetraoctylammonium bromide surfactants in conc. hydrochloric acid media. the sizes and shapes of s-nps were confirmed by scanning electron microscope (sem),transmission electron microscopy (tem) and x-ray diffraction (xrd) techniques. broth micro-dilution method was applied to determine antibacterial activity of s-nps against staphylococcus aureus,escherichia coli and pseudomonas aeruginosa reference strains. s-nps exhibited antimicrobial activity (mic = 5.47μg/ml) against staphylococcus aureus strain (gram-positive bacterium). on the other hand,no antimicrobial activity was detected against gram-negative bacteria isolates (escherichia coli and pseudomonas aeruginosa) at 0.68 to 800 μg/ml.
