  • Fluorescence dye tagging scheme for mercury quantification and speciation
    Patent number: 9139550
    Abstract: A fluorescent dye or fluorophore capable of forming complexes with mercury comprises 6,8-difluoro-7-hydroxy-2-oxo-2H-chromene-3-carboxylate amide, wherein the amide is formed by reacting the succinimidyl ester (Pacific Blue™) with an amino acid containing a thiol group, such as cysteine or glutathione. Mercury complexes of the fluorophore fluoresce when excited by a UV or violet laser diode, and the detected intensity can be calibrated to quantify the concentration of mercury in a sample reacted with the fluorophore.
    Type: Grant
    Filed: August 9, 2012
    Date of Patent: September 22, 2015
    Assignee: Los Gatos Research
    Inventors: Hong Jiao, Hannah Catterall
