Figure 6. (A) ELF and the structure models and adsorption energy values for absorbing H₂O₂ based on DFT calculation of CN and CNQDs. (B) Schematic illustration of the strategy for the preparation of CNQDs with NVs in propylene glycol under sonication: CNQDs can efficiently kill bacteria by binding to bacteria through cellular internalization and simultaneously generating ROS by their POD-like catalysis.

(D) Energy profile diagram for H₂O₂ reduction on CNNDs and Cu-CNNDs. The blue, gray, red, white, and orange balls refer to the N, C, O, H, and Cu atoms, respectively.
