细胞膜修饰纳米粒药物递送系统的研究进展

纳米粒是药物递送系统研究的热点之一，但仍存在体内循环时间短，易被网状内皮系统识别和清除等缺点，限制了其临床应用。近年来，天然细胞膜成分和纳米技术的结合为解决这些问题提供了新的方案。一种由纳米粒核和细胞膜壳组成的新型仿生系统极大地改善了纳米粒的性能。用细胞膜修饰的纳米粒具有独特的功能，如延长血液循环时间，提高主动靶向和增强细胞内化等功能。本文综述了细胞膜修饰纳米粒药物递送系统的最新进展及其在癌症治疗方面的应用前景。

Research Progress of Cell Membrane Modified Nanoparticle Drug Delivery System

Nanoparticles that are research hotspots in drug delivery systems, still have some disadvantages such as short circulation time in vivo, ease of recognition and clearance by reticuloendothelial system, which limit clinical applications. In recent years, the combinations of natural cell membrane components and nanotechnology have provided new solutions to these problems. A novel bionic system composed of nanoparticle core and cell membrane shell greatly can improve the performance of nanoparticles. Nanoparticles coated by cell membranes are endowed with unique functions such as prolonged blood circulation, active targeting capability and enhanced internalization. This review focus on the newest development of cell membrane- modified nanoparticles drug delivery systems and introduce their application prospects in cancer therapy.
