Nanoparticles (NPs) loaded with therapeutics provide a way to target the delivery of drugs to specific locations in the body. When injected intravenously, however, nanoparticles are often recognized by the immune system and rapidly cleared from the body. Efforts to extend their residence time in vivo have focused on modifying particle surfaces to evade the body’s natural defenses. Polyethylene glycol (PEG) is currently the gold standard for such nanoparticle stealth coating, but the recent observation of an anti-PEG immunological response has spurred the search for improvements. To address this challenge, researchers have looked to nature, which has created the ideal drug-delivery vehicle — red blood cells (RBCs).
