Abstract Bacterial infections and tumor tissues are characterized by complex microenvironments with uneven oxygen availability. Effective photodynamic therapy for these conditions requires photosensitizers that can perform optimally within such environments, specifically generating both type I II reactive species (ROS) simultaneously. Carbon dots (CDs), a of fluorescent nanomaterial smaller than 10 nm, commonly used to treat bacterial tumors. However, their current limitations, as short maximum absorption emission wavelengths, significantly restrict therapeutic efficacy in deep tissues. In response challenges, new carbon near‐infrared (NIR) properties is reported, featuring peak beyond 700 nm (NIR‐I region). These CDs offer strong tissue penetration reduced advantages. Additionally, bromine atom doping enhances the generation ROS through efficient processes. vitro studies demonstrated high antibacterial antitumor applications. Ultimately, findings translate into significant effectiveness treating skin tumors vivo. This study employs bromine‐doped nanomaterials, which demonstrate fluorescence NIR region, achieve treatment ablation microenvironments.

Abstract Photocatalysis is an emerging field that exploits light‐absorbing catalysts to yield transformations not even achievable in the dark. Considering drawbacks of metal‐based photocatalysts, Carbon Dots (CDs) recently emerged as suitable green alternatives for different photocatalytic reactions. These carbon nanoparticles are easy prepare, non‐toxic and potentially recyclable. Moreover, CDs usually display core‐shell structures which highly tunable via synthetic post‐synthetic strategies. This Concept Article focuses on recent advancements CD‐based photocatalysis, highlighting link between their superficial core composition resulting photo‐redox abilities, giving future perspectives application cutting‐edge areas.
