摘要:
文题释义:
近红外光响应水凝胶:由聚合物网络和近红外光响应官能团组成,通过光敏基团将近红外光信号转化为物理或化学信号,继而调控水凝胶的理化性质。由于其能够实现远程时空控制和动态调节材料行为,成为一类新兴的生物医用材料。
背景:近红外光响应水凝胶具有高度时空精准性、远程可调性及安全无创性等多种优异特性,为组织工程的发展提供了新的探索方向。
目的:总结近年来近红外光响应水凝胶在组织工程领域的应用进展。结果与结论:①近红外光响应材料通过控制感染减轻炎症、促进血管生成、促进成骨细胞分化和新骨形成等过程参与组织修复。②近红外光响应材料可以通过构建具有光热效应的热敏水凝胶或者利用光化学反应制备近红外光响应水凝胶。③近红外光响应水凝胶作为伤口敷料在软组织愈合再生过程中,通过聚合物单体的聚合作用实现快速止血及组织黏附等作用,利用光热纳米材料局部光热效应促进抗菌抗炎、促进血管形成和上皮再生等功能。④近红外光响应水凝胶在骨重建修复过程中,通过促进间充质干细胞成骨分化、刺激热休克蛋白的表达、增加血管新生等发挥促进修复作用。⑤目前近红外光响应水凝胶与多种治疗策略的组合已呈现出显著协同治疗功能,也被逐步开发应用于其他组织重建和疾病治疗场景。

文题释义:
近红外光响应水凝胶:由聚合物网络和近红外光响应官能团组成,通过光敏基团将近红外光信号转化为物理或化学信号,继而调控水凝胶的理化性质。由于其能够实现远程时空控制和动态调节材料行为,成为一类新兴的生物医用材料。骨及软组织再生是一个涉及多种生物化学和生物物理信号调节复杂的生理过程,需要多种细胞、细胞外基质、生长分子的参与并相互作用。组织工程是再生医学的一个重要领域,它结合细胞、生长因子以及支持细胞附着、迁移和增殖的可降解支架来模拟骨及软组织再生过程。水凝胶是一种亲水性的三维聚合物网络,因其与天然细胞外基质相似,可以允许细胞和生物分子的附着,并具有出色的生物降解性、生物相容性,使其从体内排出而没有任何免疫或炎症反应,机械性能可调性强等特点,成为近年来发展极为迅速的高分子材料之一,已被广泛用于组织工程、药物递送及分子成像等生物医学领域。传统的静态水凝胶不具有各向异性因而不能满足生物医学中动态调控和模仿体内环境的要求。基于对环境变化敏感响应的智能水凝胶应运而生。与其他外部刺激相比,光响应水凝胶因其远程易操控性、高度时空精准性成为理想的智能水凝胶材料,可为患者提供个性化治疗,在组织工程领域具有巨大的应用前景。
