Efficiency and Mechanisms of Bactericidal Effect of Superhydrophilic Magnesium Alloy Surface against Escherichia coli
Abstract—The surface of the MA8 magnesium alloy, modified by laser treatment, was found to acquire superhydrophilic properties and high bactericidal activity against Escherichia coli K12 C600. The main mechanisms of bactericidal action were disruption of the integrity of the bacterial outer membrane, which was perforated by nanoparticles on a textured surface, and alkalization of the dispersion medium when it interacted with the metal. The proposed method opens up new prospects for metal protection against biocorrosion by creating superhydrophilic coatings with high bactericidal properties.
