Abstract
A method for manufacturing a chip that includes a microchannel is described, wherein the method includes the steps of: fixing a cationic polymer having a quaternary onium group to at least one surface of each of a pair of resin substrates; and joining the resin substrates together on the surfaces on which the cationic polymer has been fixed.
Claims6
An electrophoresis chip comprising:
- a first resin substrate and a second resin substrate;
- and
- a microchannel between the first and second resin substrates,
- wherein a surface of the first resin substrate and a surface of the second resin substrate face each other and a cationic polymer having a quaternary onium group is fixed on the facing surfaces of the first resin substrate and second resin substrate, and
- wherein the first and second resin substrates are joined together via the cationic polymer.
