Popis: The aim of this study is to fabricate a highly porous scaffold based on gelatin/sodium alginate/45S5 bioglass with improved mechanical strength. Glycidoxypropyltrimethoxysilane (GPTMS) is used as a cross-linker and for the first time a nonionic bio-surfactant (Tween 80) is introduced to the composition to evaluate whether the essential properties of a suitable scaffold for bone substitution can be reached or not. The composite scaffolds are prepared through freeze-drying of suspension containing various ratios of gelatin/sodium alginate/45S5 bioglass. Characterization of fabricated scaffolds is carried out. SEM micrographs reveal that all samples are highly porous however incorporation of 1%
