Single Benzene Green Fluorophore: Solid‐State Emissive, Water‐Soluble, and Solvent‐ and pH‐Independent Fluorescence with Large Stokes Shifts
TL;DR: 2,5-bis(methylsulfonyl)-1,4-diaminobenzene is presented as a novel architecture for green fluorophores, established based on an effective push-pull system supported by intramolecular hydrogen bonding and demonstrates high fluorescence emission and photostability.

Simultaneous determination of pH, urea, acetylcholine and heavy metals using array-based enzymatic optical biosensor.
Hsiao-chung Tsai,Ruey-an Doong +1 more
TL;DR: An array-based optical biosensor for the simultaneous analysis of multiple samples in the presence of unrelated multi-analytes was fabricated and exhibited high specificity in identifying multiple analytes.

Solution and Fluorescence Properties of Symmetric Dipicolylamine-Containing Dichlorofluorescein-Based Zn2+ Sensors
TL;DR: The mechanism by which dipicolylamine (DPA) chelate-appended fluorophores respond to zinc was investigated by the synthesis and study of five new analogues of the 2′,7′-dichlorofluorescein-based Zn2+ sensor Zinpyr-1 (ZP1) as mentioned in this paper.

Luminescence and stability of aqueous thioalkyl acid capped CdSe/ZnS quantum dots correlated to ligand ionization.
W. Russ Algar,Ulrich J. Krull +1 more
TL;DR: Overall, the luminescence of thioalkyl acid capped QDs appears to be a complex function of dielectric constant, electrostatic or hole-acceptor interactions with ionized ligands, and, to a lesser extent, passivation.

Subattomole amino acid analysis by capillary zone electrophoresis and laser-induced fluorescence
TL;DR: The alanine detection limit corresponds to fewer than 6000 molecules injected onto the column and represents an improvement of four orders of magnitude in the state of the art for fluorescent detection of amino acids and an improvement for the detection limit for isothiocyanate derivatives of amino amino acids.
