In the article, we showed the unconventional method to determine the degradation of Bioglass 45S5 doped with samarium ions used as an optical probe. The strongest emission at the wavelength of 601 nm has been observed under 405 nm laser excitation. We used the alternative method of fiber drawing from the 45S5 glass. Bioactive glass fiber was immersed in Sorensen buffer at temperature 37°C. In situ analysis of luminescence signal of glass fiber shown a decrease in intensity within 24 hours. This effect was connected with partial surface degradation of bioglass fiber.
The paper presents thermal and mechanical properties of bioactive S53P4 BoneAlive® and glass13-93 fibers. The aim is to fabricate bioactive glass fibers from the well-known bone reconstructive S53P4 and 13-93 glasses. Examined glasses were drawn using the modified rod-in-tube method. In this study tensile strengths for S53P4 and 13-93 fibers on mean diameters 39 and 34μm respectively were measured. Differential scanning calorimetry of this materials before and after drawing process was also investigated. Bioactive fibers have been considered for future medical application for reinforcing nanocomposites.
