Abstract:
1. A centrifugal micro-fluidic device comprising: at least one micro-fluidic structure comprising a chamber and at least one channel connected with the chamber; and a detection unit, wherein the chamber comprises a reaction chamber in which a detectable signal generator is combined with an analyte of a liquid specimen to create a detectable signal generator-analyte complex, and an analysis chamber located downstream from the reaction chamber, wherein the analysis chamber comprises a detection region provided in the form of a strip where a capture binder is combined with the detectable signal generator-analyte complex, and a holder which is directly connected to the reaction chamber through a channel and carries a fluid provided from the reaction chamber, and the holder is disposed between the analysis chamber and a stoppage chamber which receives a portion of the fluid from the analysis chamber after a reaction is completed, wherein the detection region includes one of porous membranes, micro-pore structures and micro-pillars, and wherein the detection region is configured to utilize capillary force to move the fluid to a first end of the analysis chamber and the detection region is configured to utilize centrifugal force to move the fluid to a second end, which is opposite to the first end, of the analysis chamber.
