Abstract
values of the FITC dye. The hollow mesoporous silica-dye nanoparticles were used to monitor intracellular pH via a ratiometric fluorescence method. The confocal images demonstrated the capacity of this broad range sensor which can differentiate simultaneously the local pH between various environments, for example, in the medium (pH = 7.2), cytosol (pH ∼ 7) and the endosome-lysosome pathway (pH = 4-5.5).
