Signal transduction is essential for the survival of living organisms, because it allows them to respond to the changes in external environments. In artificial systems, signal transduction has been exploited for the highly sensitive detection of analytes. Herein, a remarkable signal transduction, upon ATP binding, in the multivalent fibrillar nanoaggregates of anthracene conjugated imidazolium receptors
信号转导对于生物体的生存至关重要,因为它可以使生物体对外部环境的变化做出反应。在人工系统中,信号转导已用于分析物的高灵敏度检测。在本文中,据报道,在ATP结合后,在蒽结合的咪唑鎓受体的多价原纤维纳米聚集体中发生了显着的信号转导。一种特定的两亲受体的聚集体在高p m时感觉到ATP如果一个ATP分子浓度过高,则基本上可以终止数千种受体的发射。多价结合和信号转导的协同合并导致了这种超猝灭,并转化为纳米聚集体对ATP检测灵敏度的显着提高,超过一百万倍。与“分子”咪唑鎓受体相比。此外,与其他核苷酸相比,ATP具有非凡的选择性。
