Abstract
This application relates to an injector that can directly inject a solution containing biomolecules into a cell nucleus of a wide range of injection targets with high efficiency. In one aspect, the injector injects a solution containing biomolecules into an injection target from an injector main body without performing injection through a given structure in a state where the given structure is inserted into the injection target. The injector may include an accommodation unit and a nozzle unit, wherein the injector satisfies given conditions.
Claims5
An injector that injects a solution containing biomolecules into an injection target from an injector main body without performing injection through a given structure in a state where the given structure is inserted into the injection target, the injector comprising:
- an accommodation unit accommodating a solution containing biomolecules;
- an ignition device configured to combust an ignition charge;
- a piston;
- a driving unit comprising a gas generating agent configured to generate a gas based on a combusted ignition charge;
- and
- a nozzle unit including an injection port through which the solution containing biomolecules flows,
- wherein the driving unit controls the piston and a combustion process of the ignition device to:
- start an injection of the solution containing biomolecules at an injection start time of 0 ms,
- vary an injection speed of the solution containing biomolecules during a time period of 0 ms and 0.20 ms, and
- maintain a maximum injection speed of the solution containing biomolecules in a range of 75 m/s to 150 m/s during the time period for 0.11 ms or longer.
