Russia Develops Antibacterial Surfaces Using 3D Printing
The unique technology could offer a new way to disinfect surfaces in public spaces.
Scientists at Tver State University have developed a breakthrough technology that turns ordinary stainless steel into a powerful weapon against bacteria. Using laser-based 3D printing, they create microscopic “islands” of copper on the steel surface that can kill dangerous microbes in just one hour. The development could significantly change how infections are fought in public spaces.
Against Bacteria and Corrosion
Unlike traditional coating methods, which are often expensive and short-lived, the new technology locally “fuses” copper into steel using a laser, the university’s press service told IT-Russia. This approach makes the coating durable, cost-effective and free of defects. The key lies in a unique process in which, under ultra-fast heating and cooling, copper particles migrate to the surface, forming an antibacterial layer.
From Computer Modeling to Biological Testing
The development is the result of joint work with international partners and a full research cycle — from computer modeling to biological testing. The project was supported by the Russian Science Foundation, and the results have been published in the prestigious international journal ACS Physical Chemistry Au.
The next step, the researchers say, is to adapt the method for different materials and industries. Russian scientists aim to offer the world a practical and affordable solution to minimize the risk of infection spread.
