dc.description.abstract | Little progress has been achieved on the synthesis of hydrophilic carbon dots (CDs), derived from polycyclic aromatic hydrocarbons, as an excellent photothermal agent. In this study, a strategy was developed to synthesize highly photoluminescent greenish-yellow emissive CDs based on nitration followed by hydrothermal carbonization of the polycyclic aromatic hydrocarbon precursor, perylene. The perylene-derived CDs (PY-CDs) exhibited an excellent NIR-light (808 nm) harvesting property toward high photothermal conversion efficiency (PCE = similar to 56.7%) and thus demonstrated remarkable NIR-light responsive photothermal bactericidal performance. Furthermore, these fluorescent PY-CD nanoprobes displayed excitation-dependent polychromatic emissions in the range of 538-600 nm, with the maximum emission at 538 nm. This enables intense multicolor biological imaging of cellular substances with long-term photostability, nontoxicity, and effective subcellular distribution. The bactericidal action of PY-CDs is likely due to the elevated reactive oxygen species amplification in cooperation with the hyperthermia effect. This study offers a potential substitute for multicolor imaging-guided metal-free carbon-based photothermal therapy. | - |
