Reversible pH-Induced Fluorescence Colour Change of Gold Nanoclusters Based on pH-Regulated Surface Interactions

Abstract

To prepare water-dispersible, biocompatible, ratiometric pH nanosensors is challenging. We report here for the first time that the emission colour of NAD+-capped AuNCs responses to the mono-/bidentate anchoring of the phosphoric groups of the ligand. The AuNCs exhibit a high luminescence (21% quantum yield) and an outstanding performance as fluorescent ratiometric pH sensor in a broad pH range.
