Abstract

In this study, a mixture of [Zn2(1,3-bis[bis(2-pyridylmethyl)aminomethyl]benzene)]4+ ([Zn2(BBPAB)]4+) and 11-mercaptoundecylphosphoric acid functionalized gold nanoparticles (Phos-AuNPs) is shown to be a highly sensitive colorimetric probe that can easily detect pyrophosphate (PPi) at less than 200 nM with the naked eye.
