Tailoring the interaction between a gold nanocluster and a fluorescent dye by cluster size: creating a toolbox of range-adjustable pH sensors

We present a novel strategy for tailoring the fluorescent azadioxatriangulenium (KU) dye-based pH sensor to the target pH range by regulating the pK(a) value of the gold nanoclusters. Based on the correlation between the pK(a) and surface curvature of ligand-protected nanoparticles, the pK(a) value...
