High Quantum Yield Nitrogen and Boron Codoped Orange Fluorescent Carbon Quantum Dots for Antibacterial and Bacterial Imaging

) (bactericidal rate > 99%), with the minimum bactericidal concentrations (MBC) being 6.90 and 6.13 mg/mL, respectively, and enabled rapid fluorescence labeling imaging of bacteria within 1 h. In this study, an integrated diagnostic and therapeutic system was constructed by combining the binding ability of boric acid groups to bacteria with the optical properties of long-wavelength orange fluorescent carbon quantum dots, providing a new avenue for the development of smart antibacterial materials.
