摘要:
文题释义:
MXene纳米粒子: MXene是一种新型的二维(2D)材料,由过渡金属碳化物、氮化物或碳氮化物组成,MXenes 拥有一系列优异的特性如亲水性、抗菌性、光热性能、导电性及良好的生物相容性,其作为伤口敷料有效功能成分具有非常可观的应用前景。
背景:MXene纳米粒子由于其独特的导电性、亲水性、抗菌性和生物相容性等特性使其作为皮肤伤口敷料有效功能成分具有非常可观的应用前景。
目的:就MXene纳米粒子的合成方法、功能特性及其在皮肤损伤修复中的应用作一综述。结果与结论:①MXene合成可分为自下而上合成和自上而下合成两种方法。合成后的MXene可以通过进一步表面修饰来增强生物相容性以便更好地应用于生物医学中。②MXene 拥有一系列优异的特性如亲水性、抗菌性、光热性能、导电性及良好的生物相容性,这些特性都是使其成为出色的皮肤修复材料的基础。③目前已有许多学者开发出了用于制作伤口敷料的新型复合材料,目前来看这些复合材料基于MXene纳米材料并充分利用了其如前所述的优异特性,在皮肤创口局部起到了杀菌、载药缓释及主动调节细胞因子等作用,能够综合其他多种生物活性剂的优点,在伤口愈合中发挥了更好的作用,尤其适用于复杂慢性伤口的治疗。④以MXene的各种性能为基础研发出的各种复合材料如MXene@PVA水凝胶和MXene@CH海绵等,在改善组织修复性能、作为药物载体修复皮肤损伤方面展现出良好的作用,其在促进皮肤修复领域正处于发展的初始阶段且具有巨大的发展前景;目前MXenes纳米粒子的特性研究及表面改性研究已较为充分,但其剂量依赖的生物毒性分子机制研究相对不全面。

文题释义:
MXene纳米粒子: MXene是一种新型的二维(2D)材料,由过渡金属碳化物、氮化物或碳氮化物组成,MXenes 拥有一系列优异的特性如亲水性、抗菌性、光热性能、导电性及良好的生物相容性,其作为伤口敷料有效功能成分具有非常可观的应用前景。皮肤伤口愈合是一个精确而复杂的过程,涉及多种细胞及细胞外成分的参与。伤口愈合过程往往出现细菌感染,细菌感染可导致伤口部位渗出物增加并抑制肉芽组织的形成,从而抑制伤口愈合。内源性生长因子不足是影响创口愈合的另一因素,目前传统敷料如纱布等仅仅能够起到遮蔽,保湿,吸收渗出,防止外部刺激伤害等被动作用,很少具备抗菌或主动调节内源性因子促进伤口愈合的作用,因此,新型敷料策略需要向传统敷料中负载一些活性物质或结合其他治疗方法以加速愈合。
