Fluorophore S:N ratios were evaluated by diluting Dextran Alexa Fluor 488 into various media and measuring the fluorescent signal emitted at a single excitation (488 nm) and emission (509 nm ...

Standard filter cubes are usually provided with fluorescent microscopes for the widespread Texas Red, FITC, TRITC, and DAPI stain fluors. Standard filter sets normally use wideband emission and ...

Because fluorescence emission is typically not sensitive ... This broadening, especially in the fluorescein excitation region, makes these bulbs superior to traditional mercury arcs.

Fluorescent molecules that absorb and emit light in the near-infrared (NIR) and short-wave infrared (SWIR) regions have ...

A new method in Nature Photonics uses electrochemical fluorescence modulation to separate overlapping signals in multicolor imaging—enhancing existing microscopes without hardware changes.

The STED beam uses the physical effect that was first described by Albert Einstein 100 years ago, namely, stimulated emission, to switch off fluorescent excitation everywhere, except in the center ...

One phosphorescence data point every 1 µs up to 10 s One fluorescence data point every 12.5 ms up to 999 s One bio/chemiluminescence data point every 40 µs up to 10 s Build-in excitation and emission ...

Researchers at the University of Pennsylvania have created the first three-dimensional optical images of human breast cancer in patients based on tissue fluorescence. Fluorescence diffuse optical ...
