4 unusual facts about Fluorescence


Japanese rice fish

They have been genetically modified to secrete various human hormones, express promoter sequences from other fish, and to make antimicrobial proteins and a protein that makes the medaka glow fluorescent green.

Pierre Auger Observatory

Meanwhile, from the Volcano Ranch (New Mexico, 1959–1978), the Fly's Eye (Dugway, Utah) and its successor the High Resolution Fly's Eye Cosmic Ray Detector called "HiRes" or "Fly's Eye" (University of Utah), the technique of the Fluorescence Detector was developed.

Rice Northwest Museum of Rocks and Minerals

Collections include petrified wood, various fossils, fluorescent minerals, meteorites, zeolites, and a variety of other minerals.

The Fridge

The upstairs balcony area was home to a market which sold fluoro clothing accessories, chai tea, etc.


Archaeamphora

These structures exhibited strong yellow-green intrinsic fluorescence when exposed to visible light with a wavelength of 500 nm (blue-green).

Astroblastoma

Fluorescence activation suggested that about 1/4 of these cells were CD133 positive CD24, CD34, and CD45 negative.

Atomic spectroscopy

Fluorescence is generally measured at a 90° angle from the excitation source to minimize collection of scattered light from the excitation source, often such a rotation is provided by a Pellin–Broca prism on a turntable which will also separate the light into its spectrum for closer analysis.

Diamond anvil cell

In this way, X-ray diffraction and fluorescence; optical absorption and photoluminescence; Mössbauer, Raman and Brillouin scattering; positron annihilation and other signals can be measured from materials under high pressure.

Glow-in-the-dark

Phosphorescence, a specific type of photoluminescence related to fluorescence (as seen in "glow in the dark" toys and materials)

Monochromatic Wavelength Dispersive X-Ray Fluorescence

Monochromatic Wavelength Dispersive X-Ray Fluorescence (MWD XRF) is an enhanced version of conventional Wavelength-dispersive X-ray spectroscopy (WDXRF) elemental analysis.

Polythiophene

As an approximation, the conjugated backbone can be considered as a real-world example of the "electron-in-a-box" solution to the Schrödinger equation; however, the development of refined models to accurately predict absorption and fluorescence spectra of well-defined oligo(thiophene) systems is ongoing.

Sidney H. Liebson

At a time when electronics had not been able to make measurements with nanosecond accuracy, he developed several techniques to accomplish this accuracy for measuring organic fluorescence decay times and organic scintillation pulse widths by indirect means.

Single-molecule FRET

Fluorescence signal is detected either using ultra sensitive CCD or CMOS cameras for wide field microscopy or avalanche photodiodes for confocal microscopy.

X-ray fluorescence holography

X-ray Fluorescence Holography (XFH) is a relatively new technique that benefits greatly from the coherent high-power X-rays available from synchrotron sources, such as the Japanese SPring-8 facility.
