摘要
以特色农产品废弃物马蹄皮为原料,通过水热法合成了氮掺杂碳量子点(N-CQDs),对温度及反应时间等合成条件进行了优化。在最佳合成条件下,得到量子产率为22%的N-CQDs,对其结构、形貌、组成、荧光及电化学性能进行分析。实验结果表明,N-CQDs稳定性良好,表现出更优异的荧光性能和电化学性能,且具有良好的生物相容性和细胞膜穿透性,可用于细胞内多色细胞成像。本研究为促进NCQDs的绿色合成及其在生物医学领域的应用提供了新的思路。
Nitrogen-doped carbon quantum dots(N-CQDs)were synthesized by hydrothermal method using horseshoe skin as raw material.The synthesis conditions of temperature and reaction time were optimized.N-CQDs with a quantum yield of 22%were obtained under the optimal synthesis conditions.The structure,morphology,composition,fluorescence and electrochemical properties of the synthesized N-CQDs were analyzed.The experimental results showed that N-CQDs were stable and exhibited better fluorescence and electrochemical properties,and had good biocompatibility and cell membrane penetration,which could be used for intracellular multicolor cell imaging.This study provides a new way to promote the green synthesis and application of N-CQDs in the biomedical field.
