Peritumoral Microgel Reservoir for Long‐Term Light‐Controlled Triple‐Synergistic Treatment of Osteosarcoma with Single Ultra‐Low Dose

Local minimally invasive injection of anticancer therapies is a compelling approach to maximize the utilization of drugs and reduce the systemic adverse drug effects. However, the clinical translation is still hampered by many challenges such as short residence time of therapeutic agents and the difficulty in achieving multi-modulation combination therapy. Herein, mesoporous silica-coated gold nanorods (AuNR@SiO2 ) core-shell nanoparticles are...
