INK JET DEVICE AND METHOD FOR PRODUCING A BIOLOGICAL ASSAY SUBSTRATE BY RELEASING A PLURALITY OF SUBSTANCES ONTO THE SUBSTRATE

摘要

The invention provides an ink jet device for producing a biological assay substrate. The device releases a plurality of substances onto the substrate from print heads, provided with the substances. The device further comprises means to subject the printed substrates to an accelerated motion. The accelerated motion which acts about perpendicular to the surface of the substrates acts to control penetration of the substances into the substrate. The invention also relates to a method for producing a biological assay substrate, and to a biological assay substrate obtainable by such method.
