The bioactive glass was analyzed to know its composition, crystallinity and morphology through Raman Spectroscopy (RS), X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM), respectively. In addition, compression strength tests were carried out on the resulting composite scaffolds. Experimental results show that the fabricated CH/BG scaffolds might be a promising composite biomaterial for bone tissue engineering, due to the XRD results, showing a pollutant-free biomaterial, and, SEM shows bioactive glass particles homogenously distributed within the chitosan matrix which suggested that the developed composite scaffolds possess the prerequisites for tissue engineering and these can be used for tissue engineering applications. 2016 artículo científico 0120-6230 https://www.redalyc.org/articulo.oa?id=43047073005 en http://www.redalyc.org/revista.oa?id=430 Revista Facultad de Ingeniería Universidad de Antioquia application/pdf Universidad de Antioquia Revista Facultad de Ingeniería Universidad de Antioquia (Colombia) Num.80 |
