摘要

发光碳点(CD)是一类重要的纳米材料,具有神奇的光致发光(PL)特性、良好的生物相容性、超强的水溶性和极低的成本等优点。其制备方法很多,主要分为自上而下和自下而上两类。为了了解量子光盘的荧光起源,人们提出了三种机制,即分子态、表面态和量子约束现象。荧光光盘在生化传感、光催化、生物成像、药物输送等相关领域有着重要的应用。本综述文章总结了量子点作为检测元件在不同目标传感方面的应用。事实上,文章讨论了几种分析物的检测,包括阴离子、阳离子、小分子、聚合物、细胞和微生物。此外,还探讨了光盘作为检测资源的未来前景。

Fluorescent carbon dots for sensing applications: a review

Fluorescent carbon dots for sensing applications: a review

Luminescent carbon dots (CDs) are important class of nanomaterials with fantastic photoluminescence (PL) properties, great biocompatibility, extraordinary solubility in water, minimal expense, and so on. There are many methods for their preparation and they are mainly classed into two groups, top-down and bottom-up approaches. In order to understand the origin of fluorescence in quantum CDs, three mechanisms have been proposed namely molecular state, surface state, and quantum confinement phenomenon. Fluorescent CDs have significant application in the fields of biochemical sensing, photocatalysis, bioimaging, delivery of drugs, and other related fields. In this review article the application of quantum dots as detecting component, for the sensing of different targets, has been summed up. In fact, the detection of several analytes including, anions, cations, small molecules, polymers, cells, and microscopic organisms has been discoursed. Moreover, the future aspects of CDs as detecting resources have been explored.
