Micro channel structure body and method of manufacturing micro channel structure body
View Patent ↗A micro channel structure body 10 in which a micro channel 3 having a predetermined cross-sectional shape is formed in a laminate where substrates 1 a , 1 b , and 1 c having formed thereon electrodes 2 a , 2 b , and 2 c made of a thin film are laminated sequentially. The above-mentioned micro channel 3 is formed in a perpendicular direction β perpendicular to a lamination direction α of the above-mentioned laminate. Inner surfaces 3 a and 3 b of the above-mentioned micro channel 3 have an acute angle θ with respect to the lamination direction α of the above-mentioned laminate. The above-mentioned plurality of electrodes 2 a , 2 b , and 2 c are formed and exposed in the lamination direction α of the inner surfaces 3 a and 3 b of the above-mentioned micro channel 3.
1. A micro channel structure body comprising:
a micro channel formed by enclosing an upper part of a recess formed inside of a laminate in which substrates and electrodes provided on said substrates are laminated sequentially so that a liquid flows inside said micro channel,
wherein said micro channel includes:
an inner surface having an acute angle with respect to a lamination direction of said laminate, and
a plurality of said electrodes exposed in said lamination direction of said inner surface,
wherein said micro channel structure body separates, analyzes, or both, a substance in the liquid by said electrodes.
2. The structure body according to claim 1 , wherein said plurality of said electrodes are exposed in said lamination direction and in a channel direction of said inner surface of said micro channel.
3. The structure body according to claim 1 , wherein said angle is between 30° and 60° (inclusive).
4. The structure body according to claim 1 , wherein the shape of the inner surface of said micro channel is formed in the shape of a triangle.
5. The structure body according to claim 1 , wherein said electrodes are formed into a shape of a rectangle at part on said substrates, and said plurality of said electrodes are exposed linearly at part of said inner surface of said micro channel at predetermined intervals in said lamination direction.
6. The structure body according to claim 2 , wherein said electrodes comprise a plurality of rectangular electrodes being formed at part on said substrates, and said plurality of said electrodes are exposed linearly at part of said inner surface of said micro channel at predetermined intervals in said lamination direction and in the channel direction of said micro channel.
7. The structure body according to claim 1 , wherein said micro channel structure body is configured to detect one of a concentration of the liquid flowing inside the micro channel and a concentration of a target substance in the liquid.
8. The structure body according to claim 1 , wherein said micro channel is extended in a direction perpendicular to the lamination direction of said laminate in said laminate.
