A fluid analysis cartridge having an improved structure in order to increase test reliability, and a fluid analysis apparatus including the same are disclosed. The fluid analysis apparatus comprises: a housing having a fluid supply part for supplying a fluid sample, and a filter member arranged such that the fluid sample supplied to the fluid supply part passes therethrough; a fluid analysis cartridge having a test unit that is connected to the housing so that the fluid sample that has passed through the filter member can be introduced and a test can be performed; and a pressure member that is arranged to pressurize the fluid analysis cartridge in order to move the fluid sample supplied to the fluid supply part to the test unit, wherein the test unit includes a first panel that has a first inflow part facing the filter member, and a second panel that is arranged to face the first panel and that has a second inflow part corresponding to the first inflow part, and the first inflow part may have a smaller width than the second inflow part.

Fluid analysis cartridge, and fluid analysis apparatus including same

A fluid analysis cartridge includes a reference well including a macromolecular coloring reagent having an optical characteristic that varies according to a thickness of the reference well, and a test well including a test reagent having an optical characteristic that varies according to a concentration of a component of a fluid sample that reacts with the test reagent and a thickness of the test well.

Fluid analysis cartridge and fluid analysis apparatus having the same

A microfluidic system includes a microfluidic device including a chamber which contains a fluid sample, a channel which is connected to the chamber and through which the fluid sample flows, and a valve which controls flow of the fluid sample through the channel; an irradiation apparatus which irradiates electromagnetic energy; and a diffuser which diffuses and distributes the electromagnetic energy irradiated by the irradiation apparatus to an irradiation region of the microfluidic device.

Microfluidic device, light irradiation apparatus, micorfluidic system comprising the same and method for driving the system

A apparatus for analyzing sample to prevent a sample from being stuck to a surface of the apparatus for analyzing sample in the course of being injected into the apparatus for analyzing sample. The apparatus for analyzing sample includes a platform having a disk shape. The platform includes chambers and channels, a sample inlet hole which is formed in an outer surface the platform and through which a sample is injected into the platform; an opening which is formed in the outer surface of the platform and through which a residual of the sample, present on the outer surface of the platform around the sample inlet hole, is introduced into a receiving space isolated from the chambers and channels; and a barrier which is formed on the outer surface of the platform around a portion of the opening to prevent the residual of the sample from moving past the opening in a radial outward direction of the platform.

Apparatus for analyzing sample

A microfluidic device and a method for measurement of biomaterials using the same. The microfluidic device includes a microfluidic structure including: a sample chamber which receives and accommodates blood; a reagent chamber which contains a luminescent reactant; a first detection chamber which contains a first material that is positively charged; a second detection chamber which is connected to the first detection chamber, and contains a second material having a boronate moiety; and at least one channel which connects the sample chamber, the reagent chamber and the first and second detection chambers.

Microfluidic device and hemoglobin measurement method using the same

A normally open valve unit to close a channel, a microfluidic device equipped with the same, and a method of driving the valve unit are provided. The valve unit includes a valve substance including a phase transition material, a valve substance chamber which communicates with the channel and in which the valve substance is disposed, and a fusion structure formed in a section of the channel in which, wherein when the valve substance contained in the valve substance chamber is fused by applied energy and flows into the section of the channel in which the fusion structure is formed, and the valve substance is heated to melt the fusion structure and conduct fused bonding of the channel, thereby closing the channel.

Valve unit, microfluidic device having the same, and method of driving the valve unit

Disclosed are a micro-fluidic structure for detecting biomolecules and a micro-fluidic device having the same. More particularly, a target material including at least two cis-diols is detected by a first material containing a boronate moiety and a second material containing another boronate moiety while generating electrical signals.
