基于红细胞的载药系统研究进展

基于红细胞(RBC)的新型药物输送系统近年来倍受关注，天然红细胞是机体固有成分，与传统药物载体相比，具有生物相容性高、体内半衰期长等优势。本文综述了红细胞药物载体的特点、制备方法及其载药的最新研究进展；同时，介绍了近年来出现的新型红细胞膜药物输送系统即红细胞膜包裹纳米粒(RBC-NP)和红细胞膜纳米海绵技术。
In recent years, erythrocyte-inspired delivery systems have gained much attention. Erythrocytes(red blood cells, RBCs)are natural components of our bodies. Compared to the conventional drug delivery systems, RBCs have such advantages, as higher degree of biocompatibility and longer half-life. Herein, characteristics for drug delivery, preparation methods and recent research of RBC carriers are reviewed. Besides the latest development on RBC membrane-camouflaged nanoparticle systems(RBC-NP)and RBC membrane nanosponges, which have emerged as new trends of erythrocyte-inspired delivery systems are introduced
