technologies (AMT) based on photopolymerization have also found application in tissue engineering. Although acrylates and methacrylates have excellent photoreactivity and afford photopolymers with good mechanical properties, their cytotoxicity and degradation products disqualify them from medical use. Within this work, (meth)acrylate‐based monomers were replaced by vinyl esters with exceptional low cytotoxicity
近年来,基于光聚合的增材制造技术(AMT)也已在组织工程中得到应用。尽管丙烯酸酯和甲基丙烯酸酯具有出色的光反应性,并为光敏聚合物提供了良好的机械性能,但它们的细胞毒性和降解产物使它们失去了医学用途的资格。在这项工作中,基于(甲基)丙烯酸酯的单体被具有极低细胞毒性的乙烯基酯所取代。本文的主要重点在于光反应性的测定以及有关新材料的机械性能和降解行为的研究。被测试的单体为AMT的加工提供了足够的光反应性。通过添加合适的填料(如羟基磷灰石(HA)),可以获得与天然骨骼相似的机械性能。疏水和亲水单体的正确比例可以调节降解行为。最后,采用最佳配方,使用数字光处理技术构建了蜂窝3D结构。©2011 Wiley Periodicals,Inc.
