Russian scientists have developed an effective antibacterial coating for titanium implants with gold nanoparticles and drugs. It reduces the risk of infection after operations and accelerates the growth of bone tissue, the press service of NUST MISIS reported. This method involves creating a porous layer on the alloy, depositing gold nanoparticles, and binding the antibiotic gentamicin using cysteine.
Scientists emphasize that their method makes it possible to apply antibacterial coatings to implants made of titanium, niobium and zirconium. These materials are already known for their biocompatibility and ability to mimic the behavior of bone tissue, as well as their high durability. The new coating contains gold nanoparticles and gentamicin molecules with a diameter of 3-5 nm, which help destroy microbes and stimulate the growth of bone tissue and blood vessels.
Researchers state that the use of small gold nanoparticles increases the effectiveness of the antibacterial coating and saves precious metal. The coating does not impair the mechanical properties of the implants and supports the growth of osteoblasts, bone tissue cells. NUST MISIS engineer Tatyana Teplyakova concluded that these alloys could be an excellent material for replacing bone tissue, which now has enhanced antibacterial properties.
