Abstract :
Materials in nanoscale dimensions have a high surface-to-volume ratio, and thus have better reactions with other materials. The development of nanotechnology over the past decades has opened up opportunities for discovering the antibacterial effects of metallic nanoparticles. In this study, the antibacterial properties of nanoparticles on aluminate (ZnAl2O4) were studied on Escherichia coli and Pseudomonas aeruginosa bacteria. Antibacterial activity was assessed by using the disk diffusion method on agar using nanoparticles on synthesized aluminate. The non-growth halo diameter indicates the sensitivity of bacteria to antimicrobials. The minimum inhibitory concentration of bacterial growth (MIC) and minimum bacterial leaching concentration (MBC) was measured by microdilution in sterile tubes. Statistical analysis was done by T-test. The results of this study showed that Pseudomonas aeruginosa sensitivity (16.06±1.8mm) was higher than E. coli (11.64±2.2mm) (p < 0.05). The minimum inhibitory concentration (MIC) and bactericidal concentration MBC of bacteria Pseudomonas aeruginosa and Escherichia coli bacteria MIC and MBC was lacking. According to the results obtained in this study, we conclude that Pseudomonas aeruginosa was more sensitive to alumina than that of E. coli against nanoparticles.
