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

ABSTRACT: Long-wavelength fluorescent carbon quantum dots, as an emerging nanomaterial, could effectively overcome the problems of low detection efficiency, strong antibacterial resistance, and severe imaging interference of traditional methods in the diagnosis and therapy of bacterial infections. Herein, an innovative design of nitrogen and boron codoped orange fluorescent carbon quantum dots (NB-CDs) with both bacterial recognition and binding, long-wavelength fluorescence fast imaging, and broad-spectrum antimicrobial function was developed. The diagnostic and therapeutic integrated nanoplatform was successfully constructed by the solvothermal method using citric acid (CA) as the carbon source, safranine T (ST) as the nitrogen dopant, and 3-aminobenzeneboronic acid (M-APBA) as the boron source.
