The invention is directed to dual-analyte fluorescent chemosensors for the direct detection and visualization (imaging) of neurotransmitters released upon exocytosis. The inventive sensor exploits the high concentration of neurotransmitters (e.g., glutamate, norepinephrine, and dopamine) and capitalizes upon the pH gradient between the vesicle and synaptic cleft.
本发明涉及用于直接检测和可视化(成像)释放于胞吐过程中的神经递质的双分析物荧光
化学传感器。该发明传感器利用了神经递质(例如,谷
氨酸、
去甲肾上腺素和
多巴胺)的高浓度,并利用了囊泡与突触间隙之间的pH梯度。
