New lab-on-a-chip device overcomes miniaturization problems

Chemists have invented a new type of tiny lab-on-a-chip device that could have a diverse range of applications, including to detect toxic gases, fabricate integrated circuits and screen biological molecules. The novel technique developed by the team involves printing a pattern of miniscule droplets of a non-volatile solvent -- an ionic liquid -- onto a gold-coated or glass surface.
