一种基于氧化石墨烯的氮掺杂碳点的表面印迹荧光传感器的制备方法及应用
摘要：
本发明属于荧光传感器材料的制备和分析化学检测领域，涉及一种基于氧化石墨烯的氮掺杂碳点的表面印迹荧光传感器的制备及其应用于4-硝基苯酚检测的方法。选取柠檬酸铵和乙二胺为碳源和氮源，制备出具有优良荧光性质的氮掺杂碳点(NCDs)。再选取氧化石墨烯(GO)为基质材料，4-硝基苯酚(4-NP)为模板分子、甲基丙烯酸为功能单体合成了一种新型表面分子印迹荧光传感器(4-NP-MIP)。最后将其应用于溶液中4-硝基苯酚的检测，发生荧光猝灭，考察该荧光传感器对4-NP的特异性识别和检测能力。该荧光传感器具有良好的稳定性，对于4-NP的荧光检测快速灵敏，能够应用于复杂样品中4-NP的特异性检测，在环境和食品中4-NP的监控和检测方面具有良好的应用价值和前景。
摘要（英）：

The invention belongs to the fields of preparation of a fluorescence sensor material and analytic chemical detection and relates to a preparation for a surface printing fluorescence sensor of nitrogen-doped carbon dots based on graphene oxide and a method for using the surface printing fluorescence sensor for detecting 4-nitrophenol. Ammonium citrate and quadrol are selected as a carbon source and a nitrogen source for preparing the nitrogen-doped carbon dots (NCDs) with excellent luminescent property. The graphene oxide (GO) is selected as a matrix material, 4-nitrophenol (4-NP) is selected as a template molecule and methacrylic acid is selected as a functional monomer so as to synthesize a novel surface printing fluorescence sensor (4-NP-MIP). The surface printing fluorescence sensor is used for detecting the 4-nitrophenol in the solution, the fluorescence quenching is performed and the specific recognition and detection capacity of the fluorescence sensor for 4-NP are surveyed. The fluorescence sensor has ultrahigh stability, is quick and sensitive for 4-NP fluorescence detection, can be applied to the specific detection for the 4-NP in a complex sample and has high application value and prospect at the aspect of monitoring and detection for 4-NP in food and environment.
