Abstract
A biotip according to an embodiment of the invention moves a reaction mixture along a longitudinal direction under the force of gravity. The biotip includes a chamber formed of a transparent material and filled with a liquid having a smaller specific gravity than the reaction mixture and immiscible with the reaction mixture, and a seal that seals the chamber. The liquid has a volume resistivity of greater than 0 Ω·cm and 5×1013 Ω·cm or less.
Claims5
A biotip that allows a reaction mixture to move along a longitudinal direction of an elongated chamber under the force of gravity,
- the biotip comprising:
- the elongated chamber formed of a transparent material;
- a pre-filled liquid that is filled in the elongated chamber, the pre-filled liquid having a different specific gravity from that of the reaction mixture and immiscible with the reaction mixture;
- and
- a seal that seals the chamber, wherein
- the pre-filled liquid has a volume resistivity that is greater than 0 Ω·cm and that is equal to or less than 5×1013Ω·cm,
- the pre-filled liquid includes:
- a first liquid that has a different specific gravity from that of the reaction mixture;
- and
- a second liquid that has a different specific gravity from that of the reaction mixture and that has a smaller volume resistivity than the first liquid, and
- wherein the first liquid is non-modified silicone and the second liquid is modified silicone.
A biotip that allows a reaction mixture to move along a longitudinal direction of each of two or more elongated chambers, which are in a tube shape, under the force of gravity,
- the biotip comprising:
- each of the elongated chambers formed of a transparent material;
- a pre-filled liquid that is filled in each of the elongated chambers, the pre-filled liquid having a different specific gravity from that of the reaction mixture and immiscible with the reaction mixture;
- two or more seals, each of the seals sealing each of the elongated chambers;
- and
- a substrate that holds the elonqated chambers within a single flat plane, the elongated chambers are spaced apart from each other in the substrate, wherein
- the pre-filled liquid has a volume resistivity that is greater than 0 Ω·cm and that is equal to or less than 5×1013 Ω·cm,
- each of the elongated chambers is aligned along a radial direction from a center of the single flat plane of the substrate, and
- the pre-filled liquid includes:
- a first liquid that has a different specific gravity from that of the reaction mixture;
- and
- a second liquid that has a different specific gravity from that of the reaction mixture and that has a smaller volume resistivity than the first liquid, wherein the first liquid is non-modified silicone and the second liquid is modified silicone.
