Near Infrared‐Activatable Platinum‐Decorated Gold Nanostars for Synergistic Photothermal/Ferroptotic Therapy in Combating Cancer Drug Resistance

Platinum‐decorated gold nanostars (Pt‐AuNS) as a novel metal nanoprodrug for combined photothermal‐ferroptotic therapy to combat cancer drug resistance. Upon NIR irradiation, the active metallic (Pt and Au) payloads are released, inducing selective cancer cell death. The mechanism of action is attributed to the intracellular GSH depletion and GPX4 inactivation,...

Engineering of a Core–Shell Nanoplatform to Overcome Multidrug Resistance via ATP Deprivation

The GOx and DOX are co‐loaded into core–shell MPDA/ZIF‐8 nanosystem to realize starvation‐therapy and enhanced‐chemotherapy. The first released GOx via acid‐triggered ZIF‐8 degradation starves cancer cells, leading to ATP deprivation to suppress P‐gp function. The subsequent release of DOX could efficiently be accumulated for conquering MDR of cancer...
