Abstract Carbon dots (CDs) with good water solubility and biocompatibility have become a research hotspot in the nano‐enzyme biomedical field. However, problems of low catalytic activity ambiguous site CDs as nanozymes still need to be addressed. In this work, loaded Cu single atoms are obtained through pyrolysis, coordination structure surface functional groups regulated by adjusting pyrolysis temperature. at 300 °C (named Cu‐CDs‐300) most carboxyl content is coordinated form CuN 2 O , which can better decompose H produce free radical beneficial catalyze oxidation 3,3′,5,5′‐tetramethylbenzidine (TMB). The v max 6.56*10 −7 m s −1 6.56 times higher than that horseradish peroxidase (HRP). Moreover, Cu‐CDs‐300 effectively lead CT26 apoptosis generating much radicals. This work demonstrates synergistic effect oxygen‐containing metal structures on peroxide‐like provides new ideas for design clear active high efficiency atom catalyst.

Hydrogels have a three-dimensional network structure and high-water content, are similar in to the extracellular matrix, often used as wound dressings. Natural polymers excellent biocompatibility biodegradability commonly utilized prepare hydrogels. Natural-polymer-based hydrogels can antibacterial bioactive properties by loading agents or being combined with therapeutics such phototherapy, which has great advantages field of treatment microbial infections. In published reviews infectious wounds, common classification criteria include function, source properties, type agent, etc. However, there few on based raw materials, description natural-polymer-based is not comprehensive detailed. this paper, principle material classification, characteristics seven types natural that be discussed, respectively, application wounds described detail. Finally, research status, limitations, prospects briefly discussed.
