Abstract
Ag- and Cu- doped aluminium oxide coatings were deposited by magnetron sputtering and their structure and composition were analyzed by means of scanning electron microscopy (SEM) and photoelectron spectroscopy (XPS). The coatings’ antimicrobial properties and efficiency against representative bacterial strains of Gram-positive, Gramnegative bacteria and fungi were analyzed by in vitro tests. The results of the study suggest that Ag and Cu doped aluminium oxide coatings possess a combined bactericidal effect and demonstrate a promising potential for various medical applications.
