“…Additionally, related studies have shown that since the presence of abundant groups around the sp 2 hybrid carbon core, CDs exhibit the characteristics of enzymatic activity that can be selectively activated ( Xia et al, 2019 ). Chen et al designed the tellurium-doped carbon quantum dots which can scavenge H 2 O 2 to protect cells under ambient condition ( Chen et al, 2020 ). Ma et al (2022) reported the CDs with excellent superoxide dismutase enzymatic activity, which could scavenge ROS effectively ( Ma et al, 2022 ).…”

Developing an efficient antioxidant for anti-inflammatory therapy via scavenging reactive oxygen species (ROS) remains a great challenge owing to the insufficient activity and stability of traditional antioxidants. Herein, we explored and simply synthesized a biocompatible carbon dots (CDs) nanozyme with excellent scavenging activity of ROS for anti-inflammatory therapy. As expected, CDs nanozyme effectively eliminate many kinds of free radicals including •OH, O2•−, and ABTS+•. Benefiting from multienzyme activities against ROS, CDs nanozyme can decrease the levels of pro-inflammatory cytokines, resulting in good anti-inflammatory effect. Taken together, this study not only sheds light on design of bioactive antioxidants but also broadens the biomedical application of CDs in the treatment of inflammation.

The precision treatment of tumors with minimal side effects is associated with improved human health and quality of life. In recent years, phototherapy has attracted significant attention in tumor therapy due to its versatility, spatiotemporal controllability, non‐resistance, and minimal side effects. Carbon dots (CDs) are considered promising phototherapy reagents because of their simple preparation, facilitated surface modification, tunable energy bands, excellent electron‐transfer capabilities, remarkable photoelectric and photothermal conversion properties, and outstanding biocompatibility. This review summarizes recent advancements in photo‐responsive CDs for photodynamic therapy and the emerging photocatalytic therapy of tumors. Finally, the article discusses the main challenges associated with the development of photo‐responsive CDs for oncology therapeutics and strategies to overcome these challenges.
