Abstract
A microfluidic chip includes an input section from which a liquid is introduced, a channel section in which the liquid flows, and an output section from which the liquid is discharged or a drug fixation section where the liquid and a drug come into contact. The channel section has a hydrophobic region in which a contact angle of a surface in contact with the liquid is 90 degrees or more and 130 degrees or less. The channel section is formed by being surrounded by at least a floor layer, a barrier layer, and an upper covering layer above a substrate, and a surface of at least one of the floor layer, the barrier layer, and the upper covering layer has the hydrophobic region.
Claims18
A microfluidic chip, comprising:
- a chip body having an input section, a channel section and an output section such that a fluid is introduced from the input section, flows in the channel section and discharged or comes into contact with a drug in the output section,
- wherein the channel section of the chip body has a hydrophobic region in which a contact angle of a surface in contact with the fluid is in a range of 90 degrees to 130 degrees.
A method for manufacturing a microfluidic chip, comprising:
- forming a floor layer on a substrate;
- forming a barrier layer above the substrate and the floor layer;
- and
- bonding an upper covering layer to the barrier layer,
- wherein a hydrophobic region is formed on a surface of at least one of the floor layer, the barrier layer, and the upper covering layer.
