This application relates to a measurement system for measuring a behavior of an ejection liquid, which is ejected into an object from an ejection device, within the object. The system includes a container part formed of a resin material. The system also includes an imaging device disposed to image, across the object, a tip surface of the container part having an ejection port formed therein and being in contact with the object from a back side of the object in a predetermined state in which the ejection port is positioned from a front side of the object. The system further includes a first emission device that emits first near infrared light to the tip surface. In such a configuration, the behavior of the ejection liquid when the ejection liquid is ejected into the object from the ejection device can be imaged and measured by the imaging device.

Measurement system, measurement method, injector, and method for injecting biomolecule-containing solution into to-be-injected cell using same

A needleless injector configured to inject an injection intended substance to an injection target region, by injecting the injection intended substance includes a nozzle portion and a pressing portion, and a predetermined gap is formed between the nozzle portion and the pressing portion. The nozzle portion is formed to have a portion of the distal end portion that comes into contact with the injection target region and has a width (a) falling within a range from 3.5 mm to 5.5 mm, and a ratio (b/a) defined by an inner diameter (b) of a portion of a distal end portion of the pressing portion that comes into contact with the injection target region by the width (a) falls within a range from 1.5 to 5.0. A part of the injection target region is received in the predetermined gap when the pressing portion presses the injection target region.

Needleless injector

This application relates to an injector in which when a solution containing biomolecules is injected into an injection target, a proportion of biomolecules that function in the injection target with respect to the injected biomolecules is large. This application also relates to a method of injecting a solution containing biomolecules into an injection target using the injector. In one aspect, the injector injects the solution containing biomolecules into the 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 a given condition.
