[Erythrocytes-camouflaged nanoparticles: a promising delivery system for drugs and vaccines].

Erythrocytes-camouflaged nanoparticles is an in vivo delivery system that uses erythrocytes or erythrocyte membrane nano vesicles as carriers for drugs, enzymes, peptides and antigens. This system has the advantages of good biocompatibility, long circulation cycle and efficient targeting. This review summarizes the type of carriers, their development history, the application of delivery strategies as well as their limitations and future challenges. Lastly, future directions and key issues in the development of this system are discussed.
