Single-particle capturing apparatus, single-particle capturing system, and single-particle capturing method

A single-particle capturing system comprising:

• a single-particle capturing unit including
• a flow channel on a substrate,
• a wave structure with a mountain portion and a valley portion on the flow channel, and
• a recess portion at a top portion of the mountain portion, the recess portion including a draw-in passage;
• and
• a liquid supply unit.

A single-particle capturing method, wherein a specimen containing a particle to be captured is supplied to a single-particle capturing apparatus including:

• a flow channel on a substrate,
• the flow channel including a wave structure with a mountain portion and a valley portion, and
• a recess portion at a top portion of the mountain portion, the recess portion including a draw-in passage, and
• the specimen is, while being supplied, sucked from the recess portion to an outside via the draw-in passage such that the particle to be captured is captured.
