- Abstract
- In this study, we developed a calorimetric sensing system for pyrophosphate (PPi) with a probe composed of phosphate functionalized-gold nanoparticles as the reporter unit and [Cu-3(1,3,5-tris[bis (pyridine-2-ylmethyDaminomethyl]-2,4,6-triethylbenzene)(6+) (2) as the receptor unit. The proposed probe allows easy detection of PPi with the naked eye, and selectively recognizes PPi with a detection limit of 320 nM. Unlike previous AuNP based-PPi sensing systems, this probe exhibits high selectivity for PPi over various other phosphate derivatives including adenosine triphosphate (ATP) and adenosine diphosphate (ADP).
