| 目的 综述碳点荧光探针在农产品快速检测中的进展，为保证农产品质量安全提供参考。方法 通过对国内外文献进行归纳总结，分析碳点的特点、检测原理和合成方法；围绕农产品中常见的重金属离子与农药检测，综述碳点荧光探针的应用进展；并就现存问题对其未来发展方向进行展望。结果 虽然碳点荧光探针在农产品快速检测中已经取得一定成果，但在荧光机理、检测灵敏度、稳定性等方面仍有一些亟待解决的问题，需要开展深入的研究。结论 碳点具有光学性质稳定、表面易于功能化、反应速度快和生物相容性好等优势，对其进行修饰、掺杂和钝化可以拓宽检测范围，提高检测性能，有望在农产品快速检测应用中发挥更重要的作用。 |
| 英文摘要: |
| The work aims to summarize the application progress of carbon dots (CDs) fluorescence probe in the rapid detection of agricultural products to provide the reference for ensuring the quality and safety of agricultural products. By summarizing literatures at home and abroad, the characteristics, detection principles and synthesis method of carbon dots were analyzed. Focused on the detection of heavy metal ions and pesticides commonly found in agricultural products, the application progress of carbon dots fluorescence probes was reviewed, and the existing problems of carbon dots were an-alyzed and their future development direction was prospected. Although carbon dots fluorescence probe had made certain achievements in the rapid detection of agricultural products, there were still some problems to be solved in the aspects of fluorescence mechanism, detection sensitivity and stability, which needed a more intensive study. Carbon dots have the advantages of stable optical properties, easy surface functionalization, rapid reaction speed and good biocompatibility, etc. The modification, doping and passivation of carbon dots can broaden the detection range and improve its detection per-formance. It is expected to play a more important role in the application of rapid detection of agricultural products. |
