CCVJ's fluorescence lifetime as a viscosity measurement tool and its possible application as a tunable picoseconds reference lifetime standard
(University of Missouri--Columbia, 2007)9-(2-carboxy-2-cyanovinyl) julolidine (CCVJ, a molecular rotor) was shown to perform as a viscosity sensitive probe. Using steady state spectroscopy, CCVJ was shown to have decreased emission intensity as the environmental ... -
Characterization of membrane viscosity changes with the novel molecular rotor FCVJ
(University of Missouri--Columbia, 2007)Membrane viscosity can be defined as the "thickness" of a cell membrane. Membrane viscosity conditions are a useful indicator of cell health. Many diseases have been reported to induce changes in afflicted cell membrane ... -
Development of high-resolution optical tomography with a larger-size projection acquisition
(University of Missouri--Columbia, 2007)In the industrial countries, the mortality from arteriosclerosis and cardiovascular diseases has been decreased, but they remain the most common circulatory disease. Recently, new tissue engineering technologies such as ... -
A fiber-optic confocal scanner for scattering tissue
(University of Missouri--Columbia, 2009)Confocal microscopy has become an important diagnostic tool in examining scattering tissues. The high resolution of confocal microscopy and its optical sectioning capabilities lend itself as a desirable modality in examining ... -
Flourescent molecular rotors as mechanosensors in biofluids
(University of Missouri--Columbia, 2005)Many disease states have associated blood viscosity changes. Molecular rotors, fluorescent molecules with viscosity sensitive quantum yields, have recently been investigated as a new method for biofluid viscosity measurement. ... -
A ratiometric fluorometer for reduced sensitivity against solvent artifacts
(University of Missouri--Columbia, 2005)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] When measuring fluorescence emission intensity, both the dye concentration and the optical absorption properties of the solvent influence the measured ... -
Ratiometric techniques to determine fluid viscosity using molecular rotors
(University of Missouri--Columbia, 2007)Molecular rotors exhibit viscosity-dependent quantum yield, potentially allowing measurements of fluid viscosity in non-mechanical manner. Several diseases are accompanied by blood plasma viscosity changes; therefore, a ...
