Abstract

A microfluidic device comprising a set of one or more, preferably more than 5, covered microchannel structures manufactured in the surface of a planar substrate. The device is characterized in that a part surface of at least one of the microchannel structures has a coat exposing a non-ionic hydrophilic polymer. The non-ionic hydrophilic polymer is preferably attached covalently directly to the part surface or to a polymer skeleton that is attached to the surface.
