Convenient methods for the direct visualization of neurotransmitter trafficking would bolster investigations into the development of neurodegenerative diseases. Here, tunable fluorescent molecular logic gates with applications to neuronal imaging have been developed. The three-input AND molecular logic gates are based on the coumarin-3-aldehyde scaffold and designed to give a turn-on fluorescence response upon
直接可视化神经递质贩运的便捷方法将支持对神经退行性疾病发展的调查。在这里,已开发出可应用于神经元成像的可调荧光分子逻辑门。三输入 AND 分子逻辑门基于香豆素-3-醛支架,旨在通过胞吐作用从分泌囊泡中共同释放谷氨酸和锌时发出开启荧光响应。光谱研究表明,在模拟胞吐作用的条件下,荧光增强了 11 倍。支架的甲基化用于优化传感器对所需激发波长的光谱曲线。介绍了阐明传感器-分析物相互作用的结合研究。
