The nano-rods of this complex were synthesized by sonochemistery method and characterized by IR spectroscopy and Scanning Electron Microscopy (SEM). The nanoparticles of silver(I) oxide were obtained by direct thermolysis at 700°C on air atmosphere and characterized by X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Energy Dispersive X-ray analysis (EDAX). The Schiff-base ligand, bulk and nano forms of complex (1) and silver (І) oxide nanoparticles have been screened for antibacterial activities. The antibacterial activities have investigated against two gram positive (Staphylococcus aureus, Enterococcus faecalis) and two gram negative (Escherichia coli, Pseudomonas aeruginosa) bacteria. The results revealed that all compounds exhibit antimicrobial activities, compounds 1 in nano-scale and silver(I) oxide have stronger antibacterial effect in comparison with Schiff base ligand and in comparison with bulk form of compounds 1}, keywords = {Silver (І) oxide,Sonochemistry,Nanoparticles,antibacterial,Thermolysis}, url = {http://www.nanochemres.org/article_127147.html}, eprint = {http://www.nanochemres.org/article_127147_8e56751dc58fc73563b3bface0db8f63.pdf} }
