fluorophore News
Fluorophore Modified to Expand Monitoring of Cell Dynamics
OSAKA, Japan, Nov. 28, 2022 — A genetically modified fluorescent protein has exhibited the shortest fluorescence emission wavelength to date, researchers at Osaka University reported. The fluorophore, named Sumire, emits 414-nm violet fluorescence from a hydrated chromophore....
Imaging System Offers Clearer Tissue Visualization
WALTHAM, Mass., March 5, 2014 — Studying proteins and disease markers could get easier, thanks to a new high-throughput imaging system called Lamina.
Stimulated Emission Enhances Fluorescence Detection
TAIPEI, Taiwan, March 4, 2014 — Stimulated emission (SE) can now be used to detect the signal-to-noise ratio (SNR) of fluorescence and convert it to a coherent signal.
Fluorescence Microscopy Given New Power
URBANA, Ill., Nov. 5, 2012 — A new method that studies the critical process of cell transport dynamics at multiple spatial and temporal scales has revealed properties of diffusive and directed motion transport in living cells.
Spectroscopy Optimizes Fluorescent Probes for DNA Study
HOUSTON, Sept. 7, 2012 — Time-resolved spectroscopy plus careful calculations can optimize photoluminescent probes for studying DNA, with results nearly twice as good as standard fluorescence spectroscopy for specific sequences, according to a new paper from Rice...
EMCCD camera redraws the boundaries of superresolution 3-D imaging
BELFAST, UK – Researchers in the US have developed a superresolution 3-D imaging technique that resolves single fluorescent molecules with >10 times the precision of conventional optical microscopy. Using an iXon+ electron multiplying CCD (EMCCD) camera from...
Solution Makes Smog Glow
PITTSBURGH, Aug. 31, 2009 – Kazunori Koide and colleagues at the University of Pittsburgh have developed a fluorescent solution that glows bright green in the presence of ozone. Compounds that can detect ozone and other oxidants are already in existence, but what makes this...
Light Powers DNA Nanomotor
GAINESVILLE, Fla., June 11, 2009 — A new mechanism created by chemists transforms light into motion, albeit at an extremely small scale. The team from the University of Florida built a new type of "molecular nanomotor" driven only by photons, or particles of light. While it is...
FILTERS/FLUOROPHORES
May 1, 2007 — Omega Optical Inc. has enhanced its online Curv-o-matic tool, an interactive database of filter and filter set spectral curves that includes fluorophore absorption and emission spectra. It has introduced new fluorophores, including fluorescent...
FRET FILTERS
Jul 1, 2006 — Available from Omega Optical is the FRET technical application note “Optimizing Filter Sets for FRET Applications.” Downloadable from the company Web site, the four-page document begins with an overview of the Förster resonance energy transfer...
