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.

Sulfur Nanoparticles was prepared by different method with different size and shapes, when the sulfur present
as  nanoparticles  they  have  many  practical  application  in  our  life.  This  paper  discuses  different  sulfur
nanoparticles synthesis,  characterizations and  application. Different methods were used for nanosize particle
synthesis; among those, chemical precipitation, electrochemical method, micro emulsion technique, composing
of oil,  surfactant, co-surfactant,  aqueous phases  with  the  specific  compositions and  ultrasonic treatment  of
sulfur-cystine solution. The sizes and shapes of (S-NPs) were characterized by scanning electron microscope
(SEM), transmission electron microscopy (TEM) and X-ray diffraction (XRD) techniques. Sulfur nanoparticles
are  very  important  application  for  anticancer,  antibacterial,  fertilizers,  pharmaceuticals,  fiber  industries,
modification of carbon nano tubes and synthesis of nano composites for lithium batteries.
