  • Ion detection sensor fabrication method and ion detection sensor fabricated by the same
    Patent number: 12025580
    Abstract: An ion detection sensor fabrication method includes: preparing an ion-sensitive film preparation solution; preparing an ion-sensitive mixed layer preparation solution by mixing the ion-sensitive film preparation solution with graphene powder; and forming an ion-sensitive mixed layer sensitive to a target ion by applying the ion-sensitive mixed layer preparation solution to fill a gap between a source and a drain spaced apart from each other and to cover at least a portion of an upper surface of each of the source and the drain.
    Type: Grant
