New BODIPY-based pH probes have been designed with excitation and emission wavelengths suitable for fluorescence microscopy and flow cytometry. These pH probes are cell-permeable, selectively label lysosomes, and can be used for noninvasive monitoring of lysosomal pH changes during physiological and pathological processes.
