【摘要】：碳量子点(carbon dots,CDs)作为一类新型的荧光纳米材料,具备很多优良的光学特性。相比于半导体量子点,其毒性低、生物相容性好、稳定性与抗光漂白性更高,这些优良的性质使其在检测食品中重金属、抗生素、病原菌、农药残留与违禁添加剂以及营养功能成分等方面有很好的发展前景。近年来,有关CDs的文献综述着重于总结其合成与光学性质,鲜有关于CDs在食品检测中的应用。本文介绍CDs的光学性质与合成方法,重点综述CDs在食品检测中的应用,并提出未来CDs的发展趋势。
[Abstract]:Carbon quantum dots (carbon dots,CDs), as a new kind of fluorescent nanomaterials, have many excellent optical properties. Compared with semiconductor quantum dots, they have lower toxicity, better biocompatibility, higher stability and better photobleaching resistance, which make them useful in the detection of heavy metals, antibiotics and pathogens in food. Pesticide residues, prohibited additives and nutritional functional components have good prospects. In recent years, the literature review of CDs has focused on its synthesis and optical properties. There are few applications of CDs in food detection. In this paper, the optical properties and synthetic methods of CDs are introduced, the application of CDs in food detection is reviewed, and the development trend of CDs in the future is proposed.
