Imaging in visible light hits a wall when it comes to imaging in tissue for two main reasons: visible light is absorbed and scattered by tissue and tissue autofluorescence occurs chiefly in the ...

A research group has discovered that near-infrared absorbing dyes, which had previously been considered to have closed-shell electronic structures, have an intermediate electronic structure, between ...

A near-infrared light beam appears harmless, as it is a low-frequency type of light that does not have a dramatic effect but ...

Washington State University scientists have created an injectable dye that illuminates molecules with near infrared light, making it easier to see what is going on deep inside the body. The new dye ...

In photosynthesis and organic photovoltaics, pigment molecules convert light into electrical charge. Chemists have now produced an unusual organic pigment, which is 'switched on' by an electrical ...

MIT chemists have created a fluorescent, boron-containing molecule that is stable when exposed to air and can emit light in the red and near-infrared range. The dye can be made into crystals (shown in ...

Inks and paints are everywhere in the world around us. As well as for writing and printing, these materials are also used for protection against the elements and aesthetic reasons. These substances ...

(Nanowerk News) Near-infrared light, whose wavelength is longer than visible light, is invisible and can pass through many substances. Organic materials that efficiently absorb near-infrared light are ...
