- Аннотация: A comparative evaluation of the antibacterial effect of silver in the form of nanoparticles and Ag+ ions was performed. Silver nanoparticulate coatings of stable and reproducible morphology were prepared on monolayer size-selected titanium-oxo-alkoxy nanoparticles deposited on glass substrates. The coatings exhibit a strong antibacterial activity towards Escherichia coli K12 AB 1157 and suppress biofilms formation. This activity is mainly related to the Ag+ ions release into aqueous solutions in dark. The deposited silver mass similar to 1 mu g.cm(-2) is smaller compared to that of Ag+ ions and nanoparticles generally reported for inhibiting Escherichia coli. The synergetic effect of the deposited nanoparticles and Ag+ ions can be suggested.
