Water-soluble carbon nanocrystals (CNCs) with electrochemiluminescence (ECL) activity were released into aqueous solution from a graphite rod by applying a scanning potential. ECL emission of CNCs observed during their preparation probably provides a useful method for monitoring and screening nanocrystal preparation. The ECL behavior and its mechanism in CNCs have been studied in detail for the first time. The results suggest promising applications of CNCs in the development of new types of biosensors and display devices in the future on the basis of their strong and stable ECL emission, good stability, low cytotoxicity, excellent water solubility, easy labeling, and environmental friendliness.
通过施加扫描电势，具有电化学发光（ECL）活性的水溶性碳纳米晶体（CNCs）从石墨棒释放到水溶液中。在制备过程中观察到的CNCs的ECL发射可能为监测和筛选纳米晶体制备提供了一种有用的方法。首次详细研究了CNCs中的ECL行为及其机制。结果表明，基于其强烈且稳定的ECL发射、良好的稳定性、低细胞毒性、优异的水溶性、易于标记和环境友好性，CNCs在未来新型生物传感器和显示设备的开发中具有广阔的应用前景。
