  • CU ION SENSOR AND CU ION SENSING METHOD
    Publication number: 20240125736
    Abstract: The present invention relates to a Cu ion sensor, which greatly improves the sensitivity to Cu by a nitrogen-rich surface of a copper nitride thin film doped with a metal material. The present invention also relates to a Cu ion sensing method, in which Cu2+ is detected by contacting the Cu ion sensor of the present invention with the solution to be tested, and using the change in electrical conductivity of a copper nitride film doped with a metal material in the presence of Cu2+ in the solution.
