Published: Oct. 17, 2023

Abstract The emergence of drug‐resistant bacteria poses a significant threat to people's lives and health as bacterial infections continue persist. Currently, antibiotic therapy remains the primary approach for tackling infections. However, escalating rates drug resistance coupled with lag in development novel drugs have led diminishing effectiveness conventional treatments. Therefore, nonantibiotic‐dependent therapeutic strategies has become imperative impede rise resistance. chemodynamic (CDT) opened up new possibility due CDT can convert H 2 O into •OH via Fenton/Fenton‐like reaction treatment. efficacy is limited by variety practical factors. To overcome this limitation, sterilization efficiency be enhanced introducing therapeutics inherent antimicrobial capability. In addition, researchers explored CDT‐based combined therapies augment its effects mitigate potential toxic side toward normal tissues. This review examines research progress field, explores various enhance presents synergistic combination other modalities. And last, current challenges faced future directions are discussed.

Carbon dots (CDs), as a new kind of fluorescent nanomaterials, show great potential for application in several fields due to their unique nano-size effect, easy surface functionalization, controllable photoluminescence, and excellent biocompatibility. Conventional preparation methods CDs typically involve top-down bottom-up approaches. Doping is major step forward design methodology. Chemical doping includes both non-metal metal doping, which an effective strategy modulating the fluorescence properties improving photocatalytic performance areas. In recent years, Metal-doped have aroused interest academics promising nano-doping technique. This approach has led improvements physicochemical optical by altering electron density distribution bandgap capacity. Additionally, issues toxicity utilization been addressed large extent. this review, we categorize metals into two groups: transition group rare-earth metals, overview advances biomedical applications these categories, respectively. Meanwhile, prospects challenges metal-doped are reviewed concluded. The aim paper break through existing deficiencies fully exploit potential. I believe that review will broaden insight synthesis CDs.
