A new, cost-effective screen-printing method enables mass production of copper ion sensors. These novel sensors demonstrate analytical performance comparable to traditional electrodes.

Area of Science:

  • Electrochemistry
  • Materials Science
  • Analytical Chemistry

Background:

  • Potentiometric ion-selective electrodes (ISEs) are crucial for measuring ion concentrations.
  • Conventional ISEs can be expensive and complex to manufacture.
  • Developing low-cost, mass-producible sensors is essential for wider application.

Purpose of the Study:

  • To present a simple, low-cost, and reproducible method for mass-producing potentiometric ion-selective electrodes for copper ions.
  • To evaluate the performance of sensors fabricated using screen-printing technology.

Main Methods:

  • Screen-printing of planar, strip sensors on plastic substrates using low-temperature cured pastes.
  • Formulation of ion-sensitive thick-film membranes based on copper (I) sulfide and copper (II) sulfide.

    • Main Results:

    • Successful fabrication of potentiometric copper ion-selective electrodes via screen-printing.
    • Demonstration that sensors can be printed on low-cost plastic substrates.
    • Copper (I) sulfide-based sensors exhibited analytical properties comparable to conventional ISEs, including determination range, sensitivity, selectivity, and response time.

    Conclusions:

    • Screen-printing offers a viable, low-cost method for mass production of copper ion-selective electrodes.
    • The developed thick-film electrodes show promising analytical performance for copper ion determination.
    • This technology has the potential to reduce the cost and increase the accessibility of copper ion sensing.
