In an open-access paper published Monday, German researchers said they found bony projections from chameleon skulls fluoresce
under ultraviolet (UV) light.
The blue laser FAF image of a healthy eye (Figure 1) will fluoresce
evenly, with attenuation of the FAF signal in the foveal region due to the presence of macular pigment.
In this case, UV light emitted by the blacklight is causing the lure to fluoresce
Under UV light, organic compounds in the shells fluoresce
(middle row)--though it's unclear exactly which compounds are fluorescing.
Working with FSAD visiting scientist Ruya Ozer, they developed metal organic frameworks grown onto cotton fibers that fluoresce
red or green when exposed to ultraviolet light, pairing these gas sensors with 3D visual art for a campus display.
The further incorporation of Ultra-Red[TM] technology within Encompass products causes the product to fluoresce
bright red under low-intensity black light (365 nm), contrasting extremely well on plastics that naturally fluoresce
blue in colour (like PVC).
Products formulated with Ultra-Rec (T), (M) technology fluoresce
bright red under low-intensity black light, contrasting well on plastics that naturally fluoresce
To do so, they used a genetically engineered mouse with cells that fluoresce
green, but which can be triggered to randomly fluoresce
one of three other colors: red, blue or yellow.
The red fluorescence contrasts extremely well on plastics that naturally fluoresce
blue in colour, and facilitates more accurate visual inspection of the bond-line area.
Many of the substances used in hydraulic and automotive systems naturally fluoresce
yellow under UV light: the same colour as other commercially available leak detection dyes, leading to the chance of false positive results from residual oil, grease or sealant.
Red fluorescing adhesives remain naturally clear, and only fluoresce
when exposed to UV light.
In fact, forensic scientists would not even have to change the magnetic brush technique they have used since the 1960s: British scientists at the University of East Anglia, Norwich, and King's College, London, have developed a process based on magnetic particles and antibodies that causes fingerprints to fluoresce
if they were made by a drug user.
