SPECTROSCOPIC CHARACTERISATION OF SOME OXIDE MATERIALS WITH BIOMEDICAL POTENTIAL. Authors: S. SIMON. |

Abstract: The phosphate based glasses and vitroceramics are oxide materials with high potential to be used in biomedical applications due to their biocompatibility and capabilities to form degradable temporary scaffolds for regeneration of hard and soft tissues. In order to confer them microbial resilience small amount of silver oxide is introduced due to antimicrobial activity of leached Ag+ cations. On such a way silver nanoparticles could be embedded in bioglass matrices. The most efficient way of characterising the local structure of such bionano-materials, essential for understanding and controlling their physical and chemical properties, is to use complementary spectroscopic methods like nuclear magnetic resonance, electron paramagnetic resonance, infrared and Raman spectroscopy. All these techniques together with X-ray diffraction and scanning electron microscopy have been applied to characterise the calcium-soda-phosphate glasses containing Ag2O up to 20 mol %. The structural features of these materials are related with their behaviour in simulated body fluids. | |||||||
