Abstract
A microchip is provided which includes a first introduction channel, second introduction channels arranged to sandwich the first introduction channel and merged with the first introduction channel from both sides, and a merge channel connected to the first introduction channel and the second introduction channels, where fluids fed from the first and the second introduction channels are merged and flow, wherein the merge channel has a tapered portion formed so that a channel width in a sandwiching direction along which the first introduction channel is sandwiched by the second introduction channels gradually increases along a fluid feeding direction.
Claims26
A microchip comprising:
- a substrate including a fluid channel structure, the fluid channel structure including a first fluid introduction channel and a second fluid introduction channel configured to meet so as to allow merging of a first fluid introduced from the first fluid channel and a second fluid introduced from the second fluid introduction channel, a tapered portion configured to be positioned after merging the first fluid and the second fluid from the first and second fluid introduction channels, and a contracted portion positioned downstream of the tapered portion, wherein the tapered portion and the contracted portion are spaced apart.
A particulate analyzing device comprising:
- a microchip, the microchip including a substrate including a fluid channel structure including a first fluid introduction channel and a second fluid introduction channel configured to meet so as to allow merging of a first fluid introduced from the first fluid channel and a second fluid introduced from the second fluid introduction channel, a tapered portion configured to be positioned after merging the first fluid and the second fluid from the first and second fluid introduction channels, and a contracted portion positioned downstream of the tapered portion, wherein the tapered portion and the contracted portion are spaced apart.
A method of manufacturing a microchip comprising:
- forming a substrate including a fluid channel structure, the fluid channel structure including a first fluid introduction channel and a second fluid introduction channel configured to meet so as to allow merging of a first fluid introduced from the first fluid channel and a second fluid introduced from the second fluid introduction channel, a tapered portion configured to be positioned after merging the first fluid and the second fluid from the first and second fluid introduction channels, and a contracted portion positioned downstream of the tapered portion, wherein the tapered portion and the contracted portion are spaced apart.
A microchip comprising:
- a substrate including a fluid channel structure, the fluid channel structure including a first fluid introduction channel and a second fluid introduction channel configured to meet so as to allow merging of a first fluid introduced from the first fluid channel and a second fluid introduced from the second fluid introduction channel, a tapered portion positioned after merging the first fluid and the second fluid from the first and second fluid introduction channels, a contracted portion positioned downstream of the tapered portion, and a constant portion positioned between the tapered portion and the contracted portion, and having a fixed depth and width, wherein the tapered portion is configured to linearly decrease in Z-axis direction.
