METHOD FOR MANUFACTURING A SHEET-LIKE REACTION PLATE, REACTION PLATE AND ITS USE

摘要

The invention relates to a method for manufacturing a sheet-like reaction plate such as paper for chemical and/or biochemical analysis. Method comprises selecting a sheet-like substrate comprising fibres of natural origin such as paper and having a hydrophilic surface, which has a contact angle of water < 90°, selecting a ink material, which has a hydrophobic surface when in layer form, whereby a contact angle of water is > 9 0°, and directly forming uncoated reaction regions ( 3', 3'') on the surface of the sheet-like substrate by applying a layer of the ink material (2) on the surface of the sheet-like substrate in a pre-determined pattern. The invention relates also to a sheet-like reaction plate and its use.
