摘要
碳点是一种具有强荧光、低毒性、荧光波长可调、无光闪烁等特性的新型荧光纳米粒子。经过近年来的发展,碳点的制备方法逐渐多样化,合成过程更加快捷、简便;使其在生化传感、环境检测等领域中得到了广泛应用。该文简述了碳点的特性及制备方法,综述了荧光碳点在金属离子、阴离子、有机小分子及生物大分子检测中的研究进展,最后提出了其发展过程存在的问题并对其应用前景进行了展望。
Carbon dots（CDs） comprise a recently discovered class of strongly fluorescent, non-toxic, emission-color-tuning, non-blinking nanoparticles with great analytical and bioanalytical poten- tial. In the past decade, the procedures for preparing C-dots have become increasingly versatile and facile, and their applications are being extended to a growing number of fields of biochemical sensing, environmental testing and so on. In this article, the progress made in the field of carbon dots in recent years, especially in latest developments of analytical and bioanalytical applications is reviewed, and the synthesis and properties of carbon dots are outlined. Finally, this review also provides perspectives on future opportunities and the remaining challenges confronting this research field.
