【 摘 要 】

This paper explores the antimicrobial activity of AlOOH and FeOOH nanostructures, and FeOOH/AlOOH composite nanostructures. The synthesized nanostructures have been examined by transmission electron microscopy, X-ray diffraction, low-temperature nitrogen adsorption, and microelectrophoresis. Antimicrobial activity is assessed by a 96-well plate method. It is shown that the synthesized nanoparticles have varying degrees of antibacterial effect on bacterial strains of E.coli and methicillin-resistant Staphylococcus aureus (MRSA). The FeOOH/AlOOH nanostructures possess the highest antibacterial activity, which indicates a synergistic antimicrobial effect of composite nanostructures.
