Ratiometric pH sensor based on mesoporous silica nanoparticles and Förster resonance energy transfer.
Incorporation of a dual-FRET dye pair into mesoporous silica nanoparticles yields sensitive and sensing-range tunable nanosensors with good reversibility that can be used for ratiometric pH measurements under a single-wavelength excitation.
