Lipid-insertion enables targeting functionalization of erythrocyte membrane-cloaked nanoparticles

Abstract

RBC membrane-cloaked polymeric nanoparticles represent an emerging nanocarrier platform with extended circulation in vivo. A lipid-insertion method is employed to functionalize these nanoparticles without the need for direct chemical conjugation. Insertion of both folate and the nucleolin-targeting aptamer AS1411 shows receptor-specific targeting against model cancer cell lines. © The Royal Society of Chemistry 2013.
