  • Fluidic device, system and method for detecting sample substance
    Patent number: 11511244
    Abstract: A fluidic device for capturing or detecting a sample substance contained in a solution includes at least two continuous circulation flow channels selected from the group consisting of: a first type continuous circulation flow channel which is formed of a first circulation flow channel and a second circulation flow channel and which is configured to circulate the solution in the first circulation flow channel and then circulate the solution in the second circulation flow channel; and a second type continuous circulation flow channel which is formed of a third circulation flow channel and a fourth circulation flow channel and which is configured to circulate the solution in the third circulation flow channel and then circulate and mix the solution in both of the third and fourth circulation flow channels, wherein any one of the circulation flow channels has a capturing section which captures the sample substance, and/or a detecting section which detects the sample substance.
