Embodiment 1
[0034] Such as Figure 1 to Figure 9 Shown is a first embodiment of a micro-droplet biological analysis reagent card, including a curved substrate 101, five curved grooves 102 and four curved channels 103 arranged on the curved substrate 101, adjacent arcs The arc-shaped grooves 102 communicate with each other through an arc-shaped channel 103; the inner wall of the arc-shaped groove 102 is provided with several protrusions 104.
[0035] Of course, the number of arc-shaped grooves 102 and arc-shaped passages 103 is only a reference implementation, which is to describe the structural principle of this solution more clearly, and should not be understood as a limitation to this solution.
[0036] Such as figure 2 , image 3As shown, the side of each arc-shaped groove 102 away from the center of the circle is the outer wall 1025, the side close to the center of the circle is the inner wall 1024, and the part connecting the inner side wall 1024 and the outer side wall 1025 is th...
Embodiment 2
[0056] Such as Figure 10 Shown is a second embodiment of a micro-droplet biological analysis reagent card. The difference between this embodiment and the first embodiment is only that the volumes of the reaction tank 1021, the washing tank 1022, and the detection tank 1023 in this embodiment, The bottom areas are all different, wherein the width of the reaction tank 1021 is 2mm, the depth is 8mm, and the bottom area is 30mm 2 ; The width of the washing tank 1022 is 3mm, the depth is 8mm, and the bottom surface area is 40mm 2 ; The detection groove 1023 has a width of 4mm, a depth of 8mm, and a bottom area of 80mm 2 . In this way, the reaction tank 1021 as a whole will be narrower, which is convenient for detecting the combination of samples and reagents, and the washing tank 1022 is wider, so that after the magnetic particles enter the washing tank 1022 from the reaction tank 1021, they can be fully wrapped by the washing solution for washing. 1023 is the widest, can coo...
Embodiment 3
[0058] The difference between this embodiment and the second embodiment is that in this embodiment, the width of the arc channel 103 is 0.5 mm, the width of the reaction tank 1021 is 1 mm, the depth is 3 mm, and the area of the bottom surface is 10 mm. 2 ; The width of the washing tank 1022 is 1mm, the depth is 3mm, and the bottom surface area is 10mm 2 ; The detection groove 1023 has a width of 1mm, a depth of 3mm, and a bottom area of 10mm 2 .
