Abstract
Provided is a fluidic device, including: a porous flow path member; an absorbent member contacting the flow path member and configured to absorb a liquid; and a barrier member covering at least a portion of the absorbent member, wherein the absorbent member contains a liquid-absorbent polymer that absorbs the liquid, and a lyophilic polymer having lyophilicity to the liquid.
Claims11
A fluidic device, comprising:
- a porous flow path member;
- an absorbent member contacting the flow path member and configured to absorb a liquid;
- and
- a barrier member covering at least a portion of the absorbent member,
- wherein the absorbent member comprises a liquid-absorbent polymer that absorbs the liquid, and a lyophilic polymer having lyophilicity to the liquid.
2 more elements
A transfer member for fluidic device fabrication, the transfer member comprising:
- a support member;
- a releasing layer stacked over the support member;
- and
- an absorbent member forming layer that is stacked over the releasing layer and comprises a liquid-absorbent polymer that absorbs a liquid, and a lyophilic polymer having lyophilicity to the liquid,
- wherein the absorbent member forming layer comprises a thermoplastic material.
2 more elements
A method for fabricating a fluidic device, the method comprising:
- contacting an absorbent member forming layer of a transfer member with a porous flow path member, and applying heat and pressure to the transfer member to thereby transfer the absorbent member forming layer onto the flow path member,.
- wherein:
- the transfer member comprises
- a support member, and
- a releasing layer stacked over the support member, and
- the absorbent member forming layer stacked over the releasing layer and comprising a liquid-absorbent polymer that absorbs a liquid, and a lyophilic polymer.
