A ratiometric fluorescence sensor for caffeine

Kay Severin, Anne-Clémence Corminboeuf, Nicolas Luisier, Albert Ruggi, Nicolas David Gaeng, Laurane Favre

The dye disodium 3,4:3’,4’-bibenzo[b]thiophene-2,2’-disulfonate can be used as molecular probe for the fluorimetric detection of caffeine in aqueous solution. The fluorescence response is attributed to non-covalent interactions of caffeine with the dye in ...

Hiding patterns with daylight fluorescent inks

Roger Hersch, Romain Rossier

We propose a method for hiding patterns within printed images by making use of classical and of two daylight fluorescent magenta and yellow inks. Under the D65 illuminant we establish in the CIELAB space the gamut of a classical cmyk printer and the gamut ...
