A new approach for the detection of hydrogen sulfide (H2S) was constructed within vesicles comprising phospholipids and amphiphilic copper complex as receptor. 1,2-Distearoyl-sn-glycero-3-phosphocholine (DSPC) vesicles with embedded metal complex receptor (1.Cu) sites have been prepared. The vesicles selectively respond to H2S in a buffered solution and show colorimetric as well as spectral transformation. Other analytes such as reactive sulfur species, reactive nitrogen species, biological phosphates, and other anions failed to induce changes. The H2S detection is established through a metal indicator displacement (MIDA) process, where Eosin-Y (EY) was employed as an indicator. Fluorescence, UV–vis spectroscopy, and the naked eye as the signal readout studies confirm the high selectivity, sensitivity, and lower detection limit of the vesicular receptor. The application of vesicular receptors for real sample analysis was also confirmed by fluorescence live cell imaging.

金属指示剂置换法选择性嵌入囊泡中的铜配合物检测H 2 S
在包含磷脂和两亲性铜络合物作为受体的囊泡中构建了一种检测硫化氢（H 2 S）的新方法。已经制备了具有嵌入的金属络合物受体（1.Cu）位点的1,2-二硬脂酰基-sn-甘油-3-磷酸胆碱（DSPC）囊泡。囊泡在缓冲溶液中选择性响应H 2 S，并显示比色和光谱转换。其他分析物，例如反应性硫，反应性氮，生物磷酸盐和其他阴离子，均无法引起变化。H 2S检测是通过金属指示剂位移（MIDA）过程建立的，其中Eosin-Y（EY）被用作指示剂。荧光，紫外可见光谱和肉眼作为信号读出研究证实了水泡受体的高选择性，灵敏度和较低的检测限。荧光活细胞成像也证实了囊泡受体在真实样品分析中的应用。
