Cholesterol-Modulated, pH Charge-Reversible Rhodamine-Cored Dendrimers for Transcytosis-Mediated Deep Tumor Delivery
Deep and uniform drug penetration into solid tumors remains a critical challenge in nanomedicine, as conventional nanocarriers relying on the enhanced permeability and retention (EPR) effect are largely confined to perivascular regions. While cellular transcytosis offers a promising active transport route to overcome...
