Supramolecular Structure-Enabled Delivery of Porphyrin to Glioblastomas Beyond the Blood-Brain Barrier
… blood-brain barrier (BBB) within infiltrative tumor tissue restricts porphyrin delivery and, thereby, therapeutic efficacy. This thesis leverages the drug delivery advantages of porphyrin supramolecular chemistry to address this limitation through the conception of two new platforms: porphyrin …
