Chemical reaction alters the colours of plasmonic prints

Plasmonic printing produces resolutions several times greater than conventional printing methods. In plasmonic printing, colours are formed on the surfaces of tiny metallic particles when light excites their electrons to ...

Patterns of glowing sharks get clearer with depth

A team of researchers led by scientists from the American Museum of Natural History has found that catsharks are not only able to see the bright green biofluorescence they produce, but that they increase contrast of their ...
