复合纳米生物医用材料的研究

生物医用材料领域中,细胞与材料间的相互作用是研究的主要课题.材料表面的微观结构对细胞的生物调控作用更为重要.纳米材料因具有一些独特的效应,如体积效应和表面效应,有利于细胞黏附、增殖和功能表达,因而作为生物医用材料特别是组织工程支架材料具有良好的应用前景.目前用于生物医用研究的纳米材料主要有无机纳米材料、高分子纳米材料以及复合纳米材料等.仿生纳米材料的研究和利用极大地促进了组织工程学的发展.本文就近年来纳米材料在生物医用材料尤其是组织工程支架材料中的应用研究现状进行了综述.

Research Actuality on Nano-composite Biomedical Materials

The study of material-cell interactions is the major subject in the field of biomedical materials.Micro-structure of materials has more remarkably biological control on proliferation and growth of cells.Nano-matreials have a perfect perspective for their volume effects and surface effects,which could enhance biologic activity,adhesiveness and proliferation of cells.At present,nano-materials including the inorganic,polymetric and composite are studied comprehensively to be used as biomaterials,especially used for tissue engineering.The investigation and utilization of biomimetic nano-materials will promote the development of tissue engineering effectively.In this article,we review the up-to-date study of preparation and application of nano-complex biomaterials.
