Dye-concentrated organically modified silica nanoparticles as a ratiometric fluorescent pH probe by one- and two-photon excitation.

Sehoon Kim1, Haridas E Pudavar, Paras N Prasad.   

Abstract

Basic dye-concentrated nanoparticles (approximately 33 nm in diameter) show fluorescence-based ratiometric pH response, by one- and two-photon excitations, with improved proton sensing ability (pKa approximately 6.4) through nanoscopic intraparticle energy transfer.
