Multi-functional SOL-GEL Coatings
POSTER: Nowadays the biomaterials are widely used in the implantology to protect, promote, or replacement of damaged parts in the living body. Strict requirements are subject on properties of biomaterials. The most important qualities of these materials are biocompatibility, strength, flexibility and corrosion resistance. From metal implants the stainless steel, titanium and its alloys are the most commonly used. Their surface can be improved by coatings containing ions or nanoparticles. These coatings increase the rate of osseo-integration and reduce risk of postoperative infection. Department of Glass and Ceramics in collaboration with the department of Metals and Corrosion Engineering and the department of Biochemistry and Microbiology has developed and characterized modified silica and titania sol-gel coatings on glass, ceramics and metals. Formation of coatings by sol-gel dip-coating technique allows to obtain very thin coatings on substrates of different shapes. Calcium phosphates and silver nanoparticles enable multi-functionality of the coated substrate. Bioactive properties were tested in vitro, the adhesion properties were tested by using the scratch and tape test. Antibacterial properties were observed on Gram-negative and Gram-positive bacteria. Cytotoxicity was measured on mouse fibroblasts and human osteosarcoma cells.
