Enhanced cellular uptake and tumor penetration of nanoparticles by imprinting the “hidden” part of membrane receptors for targeted drug delivery

Abstract

The widely existing transmembrane helices can serve as a novel type of binding site for recognizing corresponding membrane receptors. Through imprinting the transmembrane domain of certain receptors, here we report the construction of polymeric nanoparticles which can achieve enhanced cellular uptake and permeability in target tissues for tumor-targeted drug delivery.
