Abstract
All of bio-related substances, such as cells or bacteria, are placed at single and independent positions. A flow cell according to the present invention is used for analyzing a bio-related substance and includes a flow passageway and an injection opening and a discharge opening that are connected to the flow passageway. The flow passageway is provided with trapping structural members for trapping the bio-related substance. The trapping structural members include a structure forming a dead water region in which the bio-related substance is trapped.
Claims16
A flow cell used for analyzing a bio-related substance, the flow cell comprising:
- a flow passageway, and an injection opening and a discharge opening that are connected to the flow passageway,
- wherein the flow passageway is provided with a trapping structural member that traps the bio-related substance, the trapping structural member including a structure forming a dead water region in which the bio-related substance is trapped,
- wherein the trapping structural member includes a slit member having a slit that passes the bio-related substance, and an accommodating member disposed on a downstream side of the slit member and facing the slit member to accommodate the bio-related substance.
An analysis method for analyzing a bio-related substance using a flow cell including a flow passageway and an injection opening and a discharge opening that are connected to the flow passageway,
- wherein the method comprises a step of forming a dead water region by a trapping structural member disposed in the flow passageway to trap the bio-related substance, wherein the trapping structural member includes a slit member having a slit that passes the bio-related substance, and an accommodating member disposed on a downstream side of the slit member and facing the slit member to accommodate the bio-related substance, and the slit has a large interval with respect to the bio-related substance, the interval being greater than the interval of a gap between the slit member and the accommodating member;
- and a step of trapping the bio-related substance in the dead water region.
An analysis device used for analyzing a bio-related substance, the analysis device comprising:
- a flow cell including a flow passageway and an injection opening and a discharge opening that are connected to the flow passageway;
- an injection mechanism that injects a sample via the injection opening;
- and
- a detection mechanism that detects the bio-related substance trapped in the flow cell,
- wherein the flow passageway is provided with a trapping structural member that traps the bio-related substance, wherein the trapping structural member includes a structure forming a dead water region in which the bio-related substance is trapped, and wherein the trapping structural member includes a slit member having a slit that passes the bio-related substance, and an accommodating member disposed on a downstream side of the slit member and facing the slit member to accommodate the bio-related substance.
