Nanomolar detection of adenosine triphosphate (ATP) using a nanostructured fluorescent chemosensing ensemble

Chem Commun (Camb). 2019 Dec 7;55(94):14135-14138. doi: 10.1039/c9cc08054f. Epub 2019 Nov 5.

Abstract

We report a novel nanostructured chemosensing ensemble PyNp-C13/UD, obtained by self-assembling uranine dye (UD) and an amphiphilic pyridinium salt PyNp-C13. The ensemble was developed for the fluorescence turn-on sensing of ATP in aqueous solutions and inside living cells. The assembly operates via an indicator displacement assay (IDA) method with an ultra-low detection limit of 6.8 nM.
