Three-Level Nanoparticle Rocket Strategy for Colorectal Cancer Therapeutics in Photothermal Therapy, Inflammation Modulation, and Cuproptosis Induction.

Adv Healthc Mater

January 2025

Department of Oncology, Guangdong Provincial People's Hospital (Guangdong Academy of Medical Sciences), Southern Medical University, Guangzhou, 510080, China.

Disturbances in intracellular copper (Cu) homeostasis can trigger cuproptosis, a new form of cell death, which, when combined with photothermal therapy (PTT), offers a promising solution to the persistent challenges in colorectal cancer (CRC) treatment. In this study, a "three-level nanoparticle rocket" strategy is developed by engineering CuO, a multifunctional Cu-based nanoenzyme that is photothermal and has electron transfer properties and antioxidant efficiency. CuO effectively remodels the inflammatory environment by scavenging reactive oxygen species, thereby overcoming the traditional limitations of PTT.
