Abstract
A biochip includes: a chamber that has a longitudinal direction; a holding unit that holds a liquid sample within a predetermined area of the chamber provided along the longitudinal direction, and releases the liquid sample from the predetermined area to an area inside the chamber by using a predetermined pressing force; and a pressed member that applies the predetermined pressing force to the liquid sample.
Claims8
A biochip comprising:
- a chamber that has a longitudinal direction;
- a holding unit that holds a liquid sample within a predetermined area of the chamber provided along the longitudinal direction, and releases the liquid sample from the predetermined area to an area inside the chamber by a predetermined pressing force;
- and
- a pressed member that applies the predetermined pressing force to the liquid sample.

A reactor comprising:
- a holder that holds a biochip that includes a chamber having a longitudinal direction, a holding unit that holds a liquid sample within a predetermined area of the chamber provided along the longitudinal direction and releasing the liquid sample from the predetermined area to an area inside the chamber by a predetermined pressing force, and a pressed member that applies the predetermined pressing force to the liquid sample;
- a driving unit that rotates the holder around a rotation axis having a horizontal component;
- and
- a first heat block disposed within a first distance range from the rotation axis and controlled to have a first temperature, and a second heat block disposed within a second distance range from the rotational axis as a range different from the first distance range and controlled to have a second temperature different from the first temperature,
- wherein the holder is so constructed that the distance between the rotation axis and one end of the chamber in the longitudinal direction is different from the distance between the rotation axis and the other end of the chamber, and that at least a part of the predetermined area lies either within the first distance range from the rotation axis or within the second distance range from the rotation axis, under the condition in which the biochip is held in the holder.

A reaction method comprising:
- injecting a liquid sample into a predetermined area of a chamber of a biochip;
- disposing the predetermined area to a predetermined temperature with the liquid sample retained within the predetermined area;
- applying the predetermined pressing force to the liquid sample to release the liquid sample from the predetermined area to an area within the chamber;
- and
- rotating the biochip around the rotation axis located in such a position that the distance between the rotation axis and one end of the chamber in the longitudinal direction is different from the distance between the rotation axis and the other end of the chamber and having a horizontal component.
