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

Folate receptor targeting silica nanoparticle probe for two-photon fluorescence bioimaging
Narrow dispersity organically modified silica nanoparticles (SiNPs), diameter ~30 nm, entrapping a hydrophobic two-photon absorbing fluorenyl dye, were synthesized by hydrolysis of triethoxyvinylsilane and (3-aminopropyl)triethoxysilane in the nonpolar core of Aerosol-OT micelles. The surface of the SiNPs were functionalized with folic acid, to specifically deliver the probe to folate receptor ...
