A pH-sensitive near-infrared fluorescent probe with alkaline pKa for chronic wound monitoring in diabetic mice

Chem Commun (Camb). 2019 Jun 20;55(51):7374-7377. doi: 10.1039/c9cc02289a.

Abstract

A pH-sensitive near-infrared fluorescent probe with alkaline pKa, AlkaP-1, was developed by incorporating a benzoyl hydrazine group into a cyanine dye. The significant fluorescence changes in the alkaline regions enable the probe to monitor the alkalization process from acute wounds to chronic wounds in diabetic mice.
