Chirality is an essential property of nature. Chiral recognition is of great significance to life sciences, pharmaceutical industry, food analysis, and so on. Chiral carbon dots (CCDs), as green nanomaterials, have great prospects in chiral sensing. However, CCDs with enantioselectivity for tryptophan (Trp) enantiomers are scarce. Moreover, most chiral sensing platforms depend on the difference of fluorescence intensity at the same emission wavelength to identify enantiomers, it is still a challenge to distinguish enantiomers by the positions of fluorescent emission peaks.

双发射手性碳点作为荧光探针，用于色氨酸对映异构体的快速手性识别


手性是自然界的基本特性。手性识别对生命科学、制药工业、食品分析等具有重要意义。手性碳点 （CCD） 作为绿色纳米材料，在手性传感方面具有很大的前景。然而，对色氨酸 （Trp） 对映异构体具有对映选择性的 CCD 很少见。此外，大多数手性传感平台依赖于相同发射波长下荧光强度的差异来鉴定对映异构体，通过荧光发射峰的位置来区分对映异构体仍然是一个挑战。
