There is provided an arrangement (100) which allows for mixing a first fluid with a second fluid at a predetermined volume mixing ratio in a capillary driven fluidic system. The arrangement (100) allows filling an initially empty mixing chamber (110) with the first fluid. The arrangement then allows emptying a predetermined fraction of the first fluid from the mixing chamber (110) such as to form an empty space in the mixing chamber (110). The arrangement then allows filling the empty space of the mixing chamber (110) with the second fluid, thereby allowing a predetermined volume of the first fluid to mix with a predetermined volume of the second fluid over time.

Methods for determining the lateral diffusion of one or more components are provided.

The present disclosure relates to a diagnostic method and a device performing the same. According to an aspect of the present disclosure, a diagnostic device is a diagnostic device that uses a test kit including a specimen plate having a specimen region in which a specimen is smeared and a patch plate configured to store a contact-type patch, which comes into contact with the specimen to stain the specimen, and the diagnostic device includes a body having a loading region in which the test kit is placed, a moving unit configured to move the patch plate and the specimen plate of the test kit relative to each other so that the specimen placed in the test kit is smeared in the specimen region, and a contact unit configured to move a structure of the test kit such that the contact-type patch comes into contact with the smeared specimen so that the smeared specimen is stained.

Nozzle Assemblies and methods of use for producing a liquid jet are disclosed that may be permit adjustable time delays between mixing of fluids and observation of reactions. An example nozzle assembly includes: a housing having an inlet and an outlet and a first channel defined therebetween, where the housing includes a gas focusing aperture defining the housing outlet; an intermediate tube disposed within the first channel of the housing, where the intermediate tube has an inlet and an outlet and defines a second channel therebetween; and a central tube disposed within the second channel of the intermediate tube, where the central tube has an inlet and an outlet and defines a third channel therebetween, where the central tube outlet is longitudinally spaced apart from the intermediate tube outlet such that the intermediate tube outlet is disposed between the central tube outlet and the gas focusing aperture's inlet.

The present disclosure relates to a tissue diagnosis device including a plate supporter configured to support a plate on which a reaction region is placed and a sample is placed in the reaction region, a patch controller configured to support the patch which contains a labeling substance that specifically labels the target substance, and control a position of the patch relative to the reaction region so that the patch provides the labeling substance to the reaction region, and a target substance detector configured to detect the labeling substance and detect the target substance included in the tissue sample.

The present disclosure relates to a blood staining patch, a method and device for a blood test using the same, and more particularly, to a patch configured to contain a staining reagent for staining blood and a method and device for economically testing blood using the same. A blood testing method according to an aspect of the present disclosure, which is a blood testing method in which a patch, which includes a mesh structure forming micro-cavities and is configured to contain a staining reagent for staining staining targets present in blood in the micro-cavities, is used to perform a blood test through staining of the staining target, includes placing blood in a reaction region, and providing the staining reagent to the reaction region using the patch configured to contain the staining reagent.

The present disclosure relates to a diagnostic method and a device performing the same. According to an aspect of the present disclosure, a diagnostic device is a diagnostic device that uses a test kit including a specimen plate having a specimen region in which a specimen is smeared and a patch plate configured to store a contact-type patch, which comes into contact with the specimen to stain the specimen, and the diagnostic device includes a body having a loading region in which the test kit is placed, a moving unit configured to move the patch plate and the specimen plate of the test kit relative to each other so that the specimen placed in the test kit is smeared in the specimen region, and a contact unit configured to move a structure of the test kit such that the contact-type patch comes into contact with the smeared specimen so that the smeared specimen is stained.

According to an aspect of the present disclosure, there is provided a polymerase chain reaction (PCR) patch which is provided as a gel type having a net-like structure forming micro-cavities, wherein at least a part of a plurality of reagents used in a PCR are contained in the micro-cavities, and when the patch contacts with an external region, the reagents contained in the micro-cavities move to at least a portion of the external region, and a PCR of a target DNA included in a sample located in the external region is performed.

The present disclosure relates to an immunoassay method for performing immunoassay by using a patch that contains antibodies. An immunoassay method according to an aspect of the present disclosure performs diagnosis by detecting a target protein from a sample to be diagnosed by using a patch which includes a mesh structural body forming micro-cavities and is configured to contain a liquid substance in the micro-cavities, and includes placing the sample to be diagnosed in a reaction region, and providing an antibodies that react specifically with a target protein to the reaction region by using a patch that contains the antibodies.

The present disclosure relates to a culturing patch, culturing method, culture test method, culture test device, drug test method, and drug test device, and the culturing patch according to an aspect of the present disclosure includes component required for growth of an object to be cultured, and a mesh structural body provided in a mesh structure forming micro-cavities in which the component required for growth are contained that is configured to come into contact with a reaction region in which the object to be cultured is placed and provide some of the contained component required for growth to the reaction region.
