摘要:
Exemplary embodiments relate to a microfluidic structure including: a plurality of sample chambers; a reaction chamber in which at least two types of materials, which respectively specifically react with at least two types of target materials, are immobilized; a detection chamber connected to the reaction chamber; a path connecting the chambers; and a valve for opening and closing the path, and a microfluidic device including the microfluidic structure. Since at least two types of materials specifically binding to target materials are immobilized in a reaction chamber of the microfluidic structure, space may be efficiently used and the target materials may be assayed in a one-step test. An internal space of the microfluidic device using the microfluidic structure, the amount of samples, and costs for manufacturing the microfluidic device may be reduced, and internal quality control may be efficiently performed using the microfluidic structure as a control for the operations.

Disclosed are a blood tester for measurement of temperature of a sample placed in a blood-testing disc using a thermochromic pigment, and a control method thereof. The disclosed blood-testing disc, the blood tester having the blood-testing disc loaded therein, and the control method of the same, are used to measure a light absorbance of the thermochromic pigment in order to determine a temperature of a sample when a biological material such as blood, blood serum, blood plasma, or sputum, is subjected to analysis, so that the test may be executed at a constant temperature. Accordingly, more reproducible and accurate results are obtainable, and temperature measurement of a sample may be simply and effectively attained by an optical analyzer built in the blood tester, without an alternative instrument or sensor for measurement thereof.
