RESUMO
Although metal-ion-binding interlocked molecules have been under intense investigation for over three decades, their application as scaffolds for the development of sensors for metal ions remains underexplored. In this work, we demonstrate the potential of simple rotaxanes as metal-ion-responsive ligand scaffolds through the development of a proof-of-concept selective sensor for Zn2+ .
RESUMO
Although the central role that zinc plays in many biological processes and important disease states is now well-established, there remains a pressing need to develop an absolute understanding of the underlying biology of zinc trafficking in terms of its dynamic and quantitative processing in specific organelles. Here we describe the modular synthesis of zinc sensors using a 'click' approach and demonstrate the applicability of our new sensors in vivo using a zebrafish model.
