Abstract
A microchip is provided that includes a flow path through which a liquid containing a micro particle flows, an orifice through which the liquid flowing through the flow path is discharged into a space outside the microchip, and a light-irradiated portion provided at a predetermined location of the flow path and configured to be irradiated with light. A width of the flow path and a depth of the flow path at the orifice are set to be smaller than a width of the flow path and a depth of the flow path at the light-irradiated portion, and the flow path is configured to gradually decrease from upstream of the orifice in a cross-section area perpendicular to a liquid-delivering direction between the light-irradiated portion and the orifice. A cartridge including the microchip is also provided.
Claims12
A microchip for analyzing a micro particle comprising:
- a flow path through which a liquid containing a micro particle flows;
- an orifice through which the liquid flowing through the flow path is configured to be discharged into a space outside the microchip;
- and
- a light-irradiated portion provided at a predetermined location of the flow path and configured to be irradiated with light,
- wherein a width of the flow path and a depth of the flow path within the microchip at the orifice are set to be smaller than a width of the flow path and a depth of the flow path within the microchip at the light-irradiated portion, and
- wherein the flow path is configured to gradually decrease within the microchip, from upstream of the orifice in a cross-section area perpendicular to a liquid-delivering direction between the light-irradiated portion and the orifice.
A cartridge comprising:
- a microchip for analyzing a micro particle comprising:
- a flow path through which a liquid containing a micro particle flows;
- an orifice through which the liquid flowing through the flow path is configured to be discharged into a space outside the microchip;
- and
- a light-irradiated portion provided at a predetermined location of the flow path and configured to be irradiated with light;
- and
- a cavity in which at least the orifice and the space in which the liquid drop discharged outside through the orifice moves are configured,
- wherein a width of the flow path and a depth of the flow path at the orifice are set to be smaller than a width of the flow path and a depth of the flow path at the light-irradiated portion,
- wherein the flow path is configured to gradually decrease from upstream of the orifice in a cross-section area perpendicular to a liquid-delivering direction between the light-irradiated portion and the orifice, and
- wherein the cavity has light transmittance for light transmitted to the light-irradiated portion.
