Abstract
Provided are a microchip including a fluid circuit consisting of a space formed therein, a light-absorbing first substrate and a light-transmitting second substrate bonded onto the first substrate, and a groove, having a V-shaped section, extending parallelly to the fluid circuit on a surface of the second substrate opposite to the first substrate on a position immediately above at least part of the fluid circuit and a method of manufacturing the same.
Claims11
A microchip, comprising a fluid circuit consisting of a space formed therein, moving a liquid present in said fluid circuit to a desired position in said fluid circuit,
- including a light-absorbing first substrate and a light-transmitting second substrate bonded onto said first substrate, and
- further including a groove, having a V-shaped section, extending parallelly to said fluid circuit on a surface of said second substrate opposite to said first substrate on a position immediately above at least part of said fluid circuit.
A microchip, comprising a fluid circuit consisting of a space formed therein, moving a liquid present in said fluid circuit to a desired position in said fluid circuit,
- including a light-absorbing first substrate and a light-transmitting second substrate bonded onto said first substrate, wherein
- said fluid circuit consists of a space formed by a groove provided on a surface of said second substrate closer to said first substrate and said first substrate, and
- the microchip further comprises a tapered structure portion including a protrusion having a sectional shape of an isosceles triangle and an apical angle of 90°.
A microchip comprising a first substrate having a recess portion divided by a partition on at least a first surface and a second substrate bonded onto at least said first surface of said first substrate, and
- including a fluid circuit constituted of said recess portion and a surface of said second substrate, wherein
- at least part of a forward end of said partition of said first substrate dividing said recess portion is welded to said second substrate through a welding rib.
