About The Intelligent Ink and Pen Company

About company

Ink Intelligent is a small company set up by Professor Andrew Mills of the School of Chemistry and Chemical Engineering at Queen’s University, Belfast, UK. The company has created inks which provide information on surfaces they come into contact with, and our first commercial product is a pen containing an ink that – in combination with light sufficient to activate the surface – responds to most surfaces that exhibit photocatalytic activity. These photocatalytic surfaces include most self-cleaning tiles, paints, concrete and glass. The ink not only reveals the presence of a photocatalytic coating, but also can provide a measure of its activity, via the speed of the colour change under defined irradiation conditions.
