This study presents a high-performance ratiometric pH optode based on the fluorophore 6,8-dihydroxypyrene-1,3-disulfonic acid (DHPDS). The two pH-sensitive terminal hydroxy groups of DHPDS facilitated dual excitation/dual emission (F(1): lambda(1,ex)=420 nm, lambda(1,em)=462 nm; F(2): lambda(2,ex)=470 nm, lambda(2,em)=498 nm) properties for ratiometric...

We have demonstrated a hierarchical self-assembly of the nanoribbons on the basis of the concept of a superamphiphile. A viologen-containing surfactant (RV) and a water-soluble electron donor, 6,8-dihydroxypyrene-1,3-disulfonic acid disodium (DHP), are mixed in water to form a charge transfer...

Since various cellular processes depend on changes in pH, the regulation of intracellular pH (pHi) is important both for the individual cell and for the organism. The mechanisms of the regulation of pHi can be investigated by monitoring pHi. In...

The pH-sensitive fluorescent dye 1,3-dihydroxy-pyrene-6,8-disulfonic acid (DHPDS) was used to measure intracellular pH (pHi) from the surface fluorescence of the isolated perfused rat liver. Monochromatic light from a fluorometer was focused on the liver with a fiber optic, emitted light...
