Abstract
Cancer is one of the leading causes of death worldwide. Many treatments have been developed so far, although effective, suffer from severe side effects due to low selectivity. Nanoparticles can improve the therapeutic index of their delivered drugs by specifically transporting them to tumors. However, their exogenous nature usually leads to fast clearance by mononuclear phagocytic system. Recently, cell membrane-camouflaged nanoparticles have been investigated for cancer therapy, taking advantages of excellent biocompatibility and versatile functionality of cell membranes. In this review, we summarized source materials and procedures that have been used for constructing and characterizing biomimetic nanoparticles with a focus on their application in cancer therapy.
