Herein, a simple two-photon turn-on fluorescent probe, -(6-acyl-2-naphthayl)-maleimide (1), based on a dual PeT/ICT quenching mechanism is reported for the highly sensitive and selective detection of cysteine (Cys) over other biothiols. The probe was applied in the two-photon imaging of Cys in cultured HeLa cells, excited by a near-infrared laser at 690 nm.
在此，报道了一种基于双电子转移/分子内电荷转移猝灭机制的简单双光子开启荧光探针-(6-酰基-2-萘基)-马来酰亚胺(1)，用于对胱氨酸（Cys）进行高灵敏度和高选择性检测，以区别于其他生物硫醇。该探针应用于培养的HeLa细胞中Cys的双光子成像，由690 nm的近红外激光激发。
