Homogeneous and crack-free with micron pores organic-inorganic composite monoliths in a binary system of Ca and Si, were prepared by means of a sol-gel route starting from polymerized vinyltrimethoxysilane, about 20-mers, and an alcoholic solutions of calcium acetate. The surfaces of the specimens were characterized using XRD, FT-IR, SEM and EDX analysis. In vitro bioactivity tests were performed in SBF and showed that all composite monoliths produced were bioactive, indicating that the composite monolith with composition VTMS : H2O : i-PrOH : Ca (OAc) 2=1 : 6 : 6 : 0.2 (mol) can be suitable for the molecular design and fabrication of bioactive tissue engineered scaffolds.
