Morpholine-modified permethyl β-cyclodextrin supramolecular nanoparticles for precise dual-targeted imaging

Abstract

Possessing dual-targeted agents toward the lysosome and cancer cells, a ternary supramolecular assembly was constructed by a morpholine-modified permethyl β-cyclodextrin, sulfonated porphyrin, and folic acid-modified chitosan via multivalent interactions. As compared with free porphyrin, the obtained ternary supramolecular assembly showed promoted photodynamic effect and achieved dual-targeted precise imaging in cancer cells.
