A near-infrared dye encapsulated in poly(ε-caprolactone) nanoparticles have been synthesized. Using Kolliphor® P188 as a surfactant, the stable nanoparticles exhibit strong fluorescence intensity and remarkable large Stokes shift.
A novel near-infrared fluorescent probe NIRM was designed and synthesized. The probe exhibited a low limit of detection for Hg2+ (3.2 nM) as well as a large Stokes shift (115 nm), which is very favorable for cell imaging studies.
A near-infrared (NIR) fluorescent probe with a large Stokes shift (143 nm) for the rapid identification of Cys over Hcy and GSH in aqueous solution was developed.
