Al2O3 Nanopowders, a Suitable Compound for Active Control of Biofouling

摘要: The formation of biofilm (Biofouling) in different surface is the great concern types fields, especially medical and health system as well membrane technology. present study deals with synthesis characterization Al2O3 nanopowders antibacterial activity which can be a potentially utilized material for biocompatible implants. Nanostructure was synthesized based on sol-gel method then, crystallite size, microstructural morphological nanostructure were determined by X-ray diffraction, electron-microscopic techniques - scanning electron microscopy (SEM) transmission (TEM). According to value particle size 20.85 nm. In following, nanoparticles assessed three gram positive negative bacteria radial diffusion assay measurement minimum inhibitory concentration (MIC). toxicity blood cells also assessed. results showed that this has potent against bacteria. antimicrobial antibiotic resistant bacterium, Staphylococcus aureus. Significant seen have greatest effect Bacillus cereus MIC 9.2 μg/ml; while, among bacterial strains, Salmonella typhimurium investigated most one 35.6 μg/ml. no cells. according acquired data study, may good inhibition formation.
