As complex organisms vary in vivo, it remains a challenging task to get fluorescence 'turn on' imaging for special targets. To address this task, we have adopted a new strategy of inducing pillararene based host-guest interactions onto biocompatible graphene. By means of fluorescence competition displacement, hydrazino-pillar[5]arene modified graphene has been synthesized and provided as a 'turn on' probe for paraquat through monitoring of the fluorescence signal both in living cells and mice.
由于复杂生物体在体内存在差异,对特殊靶点进行荧光“开启”成像仍然是一项具有挑战性的任务。为了解决这一任务,我们采用了一种新策略,即在生物相容性石墨烯上诱导基于柱芳烃的主客体相互作用。通过荧光竞争置换,合成了肼基柱[5]芳烃修饰的石墨烯,并通过监测活细胞和小鼠体内的荧光信号,将其作为百草枯的“开启”探针。
