In this study, carbon dots (MCDs) were synthesized from mushrooms using hydrothermal method. The MCDs exhibited bright blue fluorescence, exceptional biocompatibility, high quantum yield, and efficient biolabeling ability. They also showed extraordinary specificity towards HOCl and could detect it in deionized water with a detection limit of 3.38 nM. Furthermore, the MCDs had potent antioxidant properties, low cytotoxicity, and high cell permeability, making them highly useful in various biological applications.
In this study, we utilized Agaricaceae, or mushrooms, as the carbon source for the hy-drothermal production of multifunctional carbon dots (MCDs). The MCDs showed remarkable features such as bright blue fluorescence, exceptional biocompatibility, high quantum yield, and efficient biolabeling ability. Moreover, the MCDs displayed extraordi-nary specificity towards HOCl, and could detect it in deionized water with a lower detection limit of 3.38 nM. Additionally, the MCDs had potent antioxidant properties, low cytotox-icity, and high cell permeability, as confirmed by DPPH and reducing potential analysis. Furthermore, the MCD probe proved to be highly useful in various biological applications, including the detection of endogenous HOCl in the RAW 264.7 cell line and the assessment of PMA-induced endogenous HOCl formation using confocal imaging. The synthesis of carbon dots (CDs) from a natural resource such as mushrooms is a promising prospect due to their exceptional physicochemical properties and broad range of potential applications. & COPY; 2023 The Author(s).
