The development of a reversible chemical sensor based on a CdSe/ZnS nanocrystal (NC) is described. Signal transduction is accomplished by fluorescence resonance energy transfer (FRET) between the NC and a fluorescent pH-sensitive squaraine dye attached to
Efficient detection of polycyclic aromatic hydrocarbons and polychlorinated biphenyls via three-component energy transfer

Reported herein is the detection of highly toxic polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) via proximity-induced non-covalent energy transfer. This energy transfer occurs in the cavity of γ-cyclodextrin, and is efficient even with the most toxic PAHs and least fluorescent PCBs. The low limits of detection and potential for selective detection using array-based systems, combined with the straightforward experimental setup, make this new detection method particularly promising.
Synthesis and photochemical properties of a new water-soluble coumarin, designed as a chromophore for highly water-soluble and photolabile protecting group

, p. 1753 - 1757 (2007/10/03)
The absorption spectra and fluorescence spectra of a coumarin derivative (1), designed to be a water-soluble photolabile protecting group for caged compounds, were successfully observed in aqueous buffer solutions at pH 2.0-12.5 for the first time. Coumar
Chemosensing in deep red: A squaraine-based fluorescent chemosensor for pH
Isgor, Yasemin G.,Akkaya, Engin U.
, p. 7417 - 7420 (2007/10/03)
We have synthesized and spectrally characterized a squaraine-based fluorescent chemosensor for pH. This chemosensor unlike many others, works in 100% aqueous solutions, signalling the pH change from 10 to 7 by a 14-fold increase in the emission intensity
