Gliomas are hard to treat because of the two barriers involved: the blood–brain barrier and blood–tumor barrier. In this study, a dual-targeting ligand, angiopep-2, and an activatable cell-penetrating peptide (ACP) were functionalized onto nanoparticles for glioma-targeting delivery. The ACP was con...
