| Abstract Scope |
Preventing infections in healthcare facilities is of prime importance. Therefore, increasing the antibacterial effectiveness of a variety of common metals is thought to be crucial. One way of improving the antibacterial properties of metals and their alloys, but not well understood, is to design their microstructures. The microstructures of lead-free brasses were tailored using severe plastic deformation. Afterward, their antibacterial properties were verified in biofilm formation experiments using the Staphylococcus aureus ATCC 25923 strain. The microstructures and bacteria-substrate interfaces were characterized using fluorescence microscopy, scanning electron microscopy, focused ion beam, and high-resolution scanning transmission electron microscopy. The obtained results clearly show that specially designed deformation and heat treatment significantly improve the antibacterial properties of metals and alloys.The work was funded by the National Science Centre in Poland under the project “Sonata bis 11”, UMO-2021/42/E/ST5/00118. |
