A variety of nanomaterials have been developed specifically for biomedical applications, such as drug delivery in cancer treatment. These materials involve both synthetic and natural nanoparticles and nanofibers of varying dimensions. The efficacy of a drug delivery system (DDS) depends on its biocompatibility, intrinsic high surface area, high interconnected porosity, and chemical functionality. Recent advances in metal-organic framework (MOF) nanostructures have led to the achievement of these desirable features. MOFs consist of metal ions and organic linkers that are assembled in different geometries and can be produced in 0, 1, 2, or 3 dimensions. The defining features of MOFs are their outstanding surface area, interconnected porosity, and variable chemical functionality, which enable an endless range of modalities for loading drugs into their hierarchical structures. MOFs, coupled with biocompatibility requisites, are now regarded as highly successful DDSs for the treatment of diverse diseases. This review aims to present the development and applications of DDSs based on chemically-functionalized MOF nanostructures in the context of cancer treatment. A concise overview of the structure, synthesis, and mode of action of MOF-DDS is provided.
人们已经开发出了多种专门用于生物医学应用的纳米材料,比如癌症治疗中的药物递送。这些材料包括各种尺寸的合成和天然纳米颗粒以及纳米纤维。药物递送系统(DDS)的功效取决于其生物相容性、固有的高比表面积、高连通孔隙率和化学功能。金属有机框架(MOF)纳米结构的最新进展已实现了这些理想特性。MOF由金属离子和有机连接体组成,它们以不同的几何形状组装,并且可以制成零维、一维、二维或三维结构。MOF的显著特点是其出色的比表面积、连通孔隙率和可变的化学功能,这使得将药物加载到其分级结构中有无数种方式。MOF结合生物相容性要求,现在被认为是治疗多种疾病的非常成功的DDS。本综述旨在介绍基于化学功能化MOF纳米结构的DDS在癌症治疗方面的发展和应用。文中简要概述了MOF-DDS的结构、合成及作用方式。
