Abstract

A detection plate includes a track region having a bottom surface having a groove provided therein, and a well apart from the track region. The well has a bottom surface. The bottom surfaces of the track region and the well are disposed substantially on a plane. This detection plate detects a specimen rapidly and highly accurately with a simple structure.

First claim

1 . A detection plate comprising:
a substrate; and a detection region provided on the substrate, wherein the detection region includes:
a track region having a first bottom surface having a track groove provided therein; and
a well apart from the track region, the well having a second bottom surface, and
wherein the first bottom surface and the second bottom surface are disposed substantially on a plane.

2 . The detection plate of claim 1 ,
wherein the detection plate is configured to be used by irradiating light scanned in a scanning direction, and wherein the track region and the well are arranged in the scanning direction.

3 . The detection plate of claim 1 , further comprising a projection provided between the track region and the well.

4 . The detection plate of claim 3 , wherein the track region, the well, and the projection are formed by integral molding.

5 . The detection plate of claim 1 ,
wherein the detection plate is configured to be used by irradiating light, and wherein an offset between the first bottom surface and the second bottom surface is not larger than an offset allowance Δz defined by a spot diameter w 0 of the light, a wavelength λ of the light, and an allowance value w(z) of the spot diameter of the light as:
Δ z={ ( w ( z )/ w 0 ) 2 −1}×π× w 0 2 /λ.

6 . The detection plate of claim 1 , wherein the well comprises a plurality of wells.

7 . The detection plate of claim 6 , further comprising a flow channel connecting the plurality of wells, wherein the second bottom surface is lower than a bottom surface of the flow channel.

8 . The detection plate of claim 1 ,
wherein the detection plate is configured to be used by irradiating light scanned in a scanning direction, wherein the track region comprises a plurality of track regions, wherein the well comprises a plurality of wells, wherein each of the plurality of track regions and respective one of the plurality of wells constitute respective one of a plurality of detection regions, and wherein the plurality of detection regions are arranged in the scanning direction.

9 . The detection plate of claim 1 , further comprising a cover layer covering the well.

10 . The detection plate of claim 1 , wherein the well has substantially a circular shape.

11 . The detection plate of claim 1 , wherein the second bottom surface has a groove provided therein.

12 . The detection plate of claim 1 , wherein the detection plate has a disk shape.

13 . The detection plate of claim 12 , wherein the track groove constitutes at least a part of a spiral groove or concentrically circular grooves.
