  • Fluorogenic compounds converted to fluorophores by photochemical or chemical means and their use in biological systems
    Patent number: 8772048
    Abstract: Fluorophores derived from photoactivatable azide-pi-acceptor fluorogens or from a thermal reaction of an azide-pi-acceptor fluorogen with an alkene or alkyne are disclosed. Fluorophores derived from a thermal reaction of an alkyne-pi-acceptor fluorogen with an azide are also disclosed. The fluorophores can readily be activated by light and can be used to label a biomolecule and imaged on a single-molecule level in living cells.
    Type: Grant
    Filed: March 1, 2012
    Date of Patent: July 8, 2014
    Assignees: Kent State University, Leland Stanford Junior University
    Inventors: Robert J. Twieg, William E. Moerner, Samuel J. Lord, Na Liu, Reichel Samuel
