Abstract
A microchip including a fluid circuit formed by a groove of a first substrate and a surface of a second substrate is provided. The fluid circuit includes a fluid retaining reservoir for containing a fluid. The fluid retaining reservoir includes a fluid outlet or outflow channel for allowing the fluid to flow out, and a partition dividing the fluid retaining reservoir into a first region including a fluid inlet for injecting a fluid into the fluid retaining reservoir and a second region including the fluid outlet or outflow channel. The partition includes at least one communication gate for allowing communication between the first region and the second region.
Claims25
A microchip comprising:
- a first substrate and a second substrate, said first substrate being superposed on said second substrate and having a surface with a groove;
- and
- a fluid circuit composed of a cavity defined by said groove and a surface on said first substrate side of said second substrate, wherein
- said fluid circuit includes a fluid retaining reservoir for containing a fluid,
- said first substrate has a fluid inlet for injecting a fluid into said fluid retaining reservoir, said fluid inlet is a through opening extending through said first substrate from a surface opposite to said surface with the groove of said first substrate to said fluid retaining reservoir,
- said fluid retaining reservoir includes:
- a fluid outlet or outflow channel for allowing the fluid to flow out;
- and
- a partition dividing said fluid retaining reservoir into a first region including said fluid inlet and a second region including said fluid outlet or outflow channel, and
- said partition includes at least one communication gate for allowing communication between said first region and said second region.
A microchip comprising:
- a first substrate and a second substrate, said first substrate being superposed on said second substrate and having a surface with a groove;
- and
- a fluid circuit composed of a cavity defined by said groove and a surface on said first substrate side of said second substrate, wherein
- said fluid circuit includes a fluid retaining reservoir for retaining a fluid,
- said fluid retaining reservoir includes:
- a fluid outlet for allowing said fluid to flow out from said fluid retaining reservoir;
- and
- a partition dividing said fluid retaining reservoir into a first region where said fluid is introduced and a second region where said fluid outlet is included,
- said partition includes a communication gate for allowing communication between said first region and said second region, and
- at least a part of said partition includes a curved portion formed of a wall in a shape of a curve as seen from a surface of said microchip.
A microchip comprising:
- a first substrate and a second substrate, said first substrate being superposed on said second substrate and having a surface with a groove;
- and
- a fluid circuit composed of a cavity defined by said groove and a surface on said first substrate side of said second substrate, wherein
- said fluid circuit includes a fluid retaining reservoir for containing a fluid,
- said fluid retaining reservoir includes:
- a fluid outlet for allowing said fluid to flow out;
- and
- at least one columnar body extending in thickness direction of said microchip, and
- said columnar body is provided in a fluid retaining region for retaining said fluid, said fluid retaining region including a position farthest from said fluid outlet.
