Carbon dots (C-dots) prepared through heating of aminoguanidine and citric acid enable bimodal (colorimetric and fluorescence) detection of nitric oxide (NO) in aqueous solutions. The C-dots retained the functional units of aminoguanidine, which upon reaction with NO produced surface residues responsible for the color and fluorescence transformations. Notably, the aminoguanidine/citric acid C-dots were noncytotoxic, making possible real-time and high sensitivity detection of NO in cellular environments. Using multiprong spectroscopic and chromatography analyses we deciphered the molecular mechanism accounting for the NO-induced structural and photophysical transformations of the C-dots, demonstrating for the first time N2 release and azo dye formation upon the C-dots’ surface.

碳点上偶氮染料形成对一氧化氮的传感
通过加热氨基胍和柠檬酸制备的碳点（C-点）能够对水溶液中的一氧化氮（NO）进行双峰（比色和荧光）检测。C点保留氨基胍的功能单元，其与NO反应后产生负责颜色和荧光转换的表面残基。值得注意的是，氨基胍/柠檬酸C点无细胞毒性，因此可以在细胞环境中实时，高灵敏度地检测NO。使用多管光谱和色谱分析，我们解释了分子机理，解释了NO诱导的C点的结构和光物理转变，首次证明了N 2的释放和C点表面上偶氮染料的形成。
