Abstract: Disclosed herein are a structure for optical analysis that is capable of optically analyzing a small amount of a sample and an ink composition for manufacturing the same. A structure for optical analysis includes a support and an ink structure coupled to the support and configured to form a chamber on one surface of the support. The ink structure includes a first ink structural component configured to form a body of the ink structure and a second ink structural component formed at a lower portion of a side surface of the first ink, such that the first ink structural component and the second ink structural component have different slopes with respect to a direction of a center of the chamber.

Abstract: Provided is a microfluidic apparatus including: a microfluidic structure for providing spaces for receiving a fluid and for forming channels, through which the fluid flows; and valves for controlling the flow of fluid through the channels in the microfluidic apparatus. The microfluidic structure includes: a sample chamber; a sample separation unit receiving the sample from the sample chamber and separating a supernatant from the sample by using a centrifugal force; a testing unit receiving the supernatant from the sample separation unit for detecting a specimen from the supernatant using an antigen-antibody reaction, and a quality control chamber for identifying reliability of the test.

Abstract: A sample test method, microfluidic device, and test device efficiently and accurately compensates for interference of an interfering substance present in a sample using optical measurement without addition of a separate reagent for detecting the interfering substance. The sample test method includes: measuring an optical characteristic value of a target substance present in a sample; measuring an optical characteristic value of an interfering substance present in the sample; and determining a concentration of the target substance for which interference of the interfering substance is compensated for based on the optical characteristic value of the interfering substance.
