Abstract: A solution filling apparatus fills a capillary with solution of a substance to be introduced into a cell. A capillary holding unit holds the capillary. An injection-tube holding unit holds an injection tube to be injected into the capillary. A solution ejecting unit ejects the solution from the injection tube into the capillary. A guiding unit guides the injection tube into the capillary. A capillary oscillating unit oscillates the injection-tube holding unit and the solution ejecting unit.

Abstract: Proposed is an apparatus for automatically producing particles having introduced therein a substance. The apparatus includes a feeding device that feeds a suspension containing a plurality of particles; a holding device that receives the suspension from the feeding device and immobilizes and release at least one particle reversibly; an injecting device that injects a substance into the particle while the particle has been immobilized by the holding device; and a removing device that removes particles that are not immobilized by the holding device.

Abstract: A device for injecting a substance into a cell includes a flow path through which a cell is transported, a transported-cell detecting unit that detects the cell transported through the flow path, a cell capturing unit that captures the cell detected by the transported-cell detecting unit, a captured-cell detecting unit that detects the cell captured by the cell capturing unit and determines a position of the cell captured, and a substance injecting unit that injects a substance into the cell captured by the cell capturing unit based on the position determined.

Abstract: An apparatus for injecting a substance into a particle includes a chip. The chip includes a base. A charging unit in which the particle is charged, an extracting unit from where the particle with the substance injected therein is extracted, a flow path that connects the charging unit to the extracting unit, and a transporting unit that makes the particle to flow in the flow path from the charging unit to the extracting unit are formed in the base. The substance is inserted in the particle with a needle while the particle is in the flow path.

Abstract: An apparatus for injecting a substance into a cell includes a cell input part to input the cell, a cell output part to output the cell, a flow path that connects the cell input part and the cell output part, wherein the cell flows in the flow path from the cell input part toward the cell output part, a trapping part that is arranged in the flow path and traps the cell that flows in the flow path, and an inserting part that allows to pass a needle that injects the substance into the cell that is trapped at the trapping part. The cell injected with the substance flows in the flow path toward the cell output part and the cell can be retrieved from the cell output part.
