  • Biosensor
    Publication number: 20050036906
    Abstract: A biosensor for analyzing specific components in an introduced liquid sample by reaction of the liquid sample with a reagent comprises a cavity into which the liquid sample is introduced, an air hole communicating from the cavity to outside, and a water repellent part having a water repellency at 43 mN/m or less in surface free energy and provided to at least a portion around the outlet of the air hole. By the water repellent part around the air hole, the liquid sample can be prevented from flowing out through the air hole, thereby achieving a high-accuracy measurement.
