Paragraph starter
The development of advanced biomaterials for tissue regeneration often involves overcoming inherent material limitations. For instance, porous ceramic scaffolds, while offering excellent bioactivity, can suffer from brittleness. Research by Goudouri et al. (2015) demonstrated that coating such scaffolds with gelatin and subsequently cross-linking the gelatin layer significantly enhanced mechanical stability while maintaining biocompatibility and promoting apatite formation, suggesting a viable strategy for improving implant performance in regenerative applications.
