建立了一种基于单6-巯基-β-环糊精修饰的Mn掺杂ZnS量子点的比率荧光检测L-色氨酸的方法。相对于其他氨基酸，它对L-色氨酸表现出高度选择性的比率发射响应（400/598 nm）。将β-环糊精包被在Mn-ZnS量子点表面后，仍保留了分子识别能力，这也是确定L-色氨酸的原因。
A ratiometric fluorescence method for the detection of L-tryptophan based on mono-6-SH-β-cyclodextrin modified Mn-doped ZnS quantum dots has been developed. It exhibits a highly selective ratiometric emission response (400/598 nm) to L-tryptophan over other amino acids. β-Cyclodextrin still retained the ability of molecular recognition when it was coated on the surface of Mn–ZnS QDs, and this is also the cause for the identification of L-tryptophan.
