Abstract
The methods for producing microchannel chips of the present invention comprise the steps of shielding substrate surfaces on which groove-like channels have been formed, using a mask that exposes the channels, and then forming polymer membranes on the exposed surfaces of the substrates; and the step of laminating cover materials onto the side of the substrate surfaces on which the channels have been formed.
Claims16
A method for producing a microchannel chip, comprising the steps of:
- a) shielding a surface of a substrate, on which a groove-like channel has been formed, with a mask that exposes the channel,
- b) forming a polymer membrane on the exposed surface of the substrate;
- and
- c) laminating a cover material on to the substrate surface on which the channel has been formed.
