Antibacterial surfaces with applications in repairing damaged bone tissue are being developed by scientists at the Institute of Electronics of BAS. The research has used ultrashort-pulse lasers to enhance the antibacterial properties of ceramic and polymer materials compatible with human tissue. The results of laboratory studies show the influence of laser radiation on the cellular composition of surfaces which is essential for the efficient repair of damaged tissues. The antimicrobial properties of laser-treated surfaces have been evaluated in interaction with different bacterial strains. Studies have shown that bacterial cells are less easily retained on the treated materials and their viability is reduced. The experimental methodology of the scientists from the Institute of Electronics confirms the non-contact surface femtosecond laser structuring of biocompatible materials as a [...]

The Institute of Polymers-BAS organized an information campaign "Open Doors Day" which took place on 26 November.
