Abstract: 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.
