Abstract: An automatic immunoassay system is provided to an automatic immunoassay apparatus and includes a well cartridge provided with a plurality of wells in which a tip mounted on the automatic immunoassay apparatus is sequentially dipped, a cartridge loading mechanism coupled to a lower portion of the well cartridge to couple the well cartridge to the holding plate, a light source unit disposed at one side of the cartridge unit to emit light to the wells, a sensing unit disposed at the other side of the cartridge unit to detect a fluorescence signal generated by light delivered to the wells, and an assay unit analyzing the fluorescence signals detected by the sensing unit.

Abstract: A sample pretreatment tube includes a first tube receiving a primary reagent and a second tube receiving a secondary reagent, wherein the sample pretreatment tube can easily perform sequential reactions by allowing a primary reaction solution to be immediately discharged from the first tube to the second tube by breaking a separation membrane formed at a lower end of the first tube using a pipette, and can limit an insertion depth of the pipette using a stopper formed inside the first tube, thereby preventing damage to the second tube due to the pipette while allowing a space to be formed inside the first tube to facilitate discharge of a primary reaction solution, thus making it possible to immediately perform secondary reaction.

Abstract: A diagnostic kit includes: a diagnostic chip formed with a flow channel through which a diagnostic sample moves; a diagnostic sample movement regulation unit opening/closing one end of the flow channel to regulate movement of the diagnostic sample; an optical information detection unit detecting optical information on the diagnostic sample; and a controller controlling operation of the diagnostic sample movement regulation unit and the optical information detection unit, wherein the optical information detection unit includes: a light source illuminating the diagnostic sample; and a sensor sensing the optical information from the diagnostic sample, the diagnostic sample movement regulation unit is operatively associated with the optical information detection unit, and the diagnostic chip and the optical information detection unit are moved relative to each other upon operation of the diagnostic sample movement regulation unit.

Abstract: Disclosed is a method of quantifying a biomarker with high sensitivity using photo-oxidation induced amplification. The method includes performing an enzyme-substrate reaction of a measurement sample including an enzyme labeled on any one selected from among an antibody, an aptamer, and a nucleic acid specifically bound to the biomarker, optically measuring one or more optical properties selected from among amounts of color formation, light emission, and fluorescence of a product during a photo-oxidation induced amplification process while the product resulting from the enzyme-substrate reaction is continuously exposed to light to thus perform the photo-oxidation induced amplification process, indexing a time-varying pattern of the measured optical properties, and quantifying a concentration of the biomarker included in the measurement sample by comparing an index extracted during the indexing with an index of a reference sample.

Abstract: An apparatus for measuring fluid speed by using the refraction of light is disclosed. The apparatus includes: a channel in which a passage is formed to allow the flow of a fluid; a first and a second light source that are located in any one region of an upper part and a lower part of the channel; a sensor installed in an opposite region of the region where the first and second light sources are located with respect to the channel, to receive the light emitted from the first and second light sources; a speed calculation unit that calculates the speed of the fluid by using a time point at which the intensity of the light received at the sensor changes; and an adjustment unit that is connected to the channel and configured to adjust the flow speed of the fluid based on the calculated speed of the fluid.
