  • Evaluation of electrochemiluminescence using ferrocyanide and tri-propylamine as co-reactant.
  • Comparison of bare titanium and gold-coated titanium arrays.

    • Main Results:

    • The 3D printed titanium array exhibited a high roughness factor and a potential window of -0.3 to +1.2 V.
    • Quasi-reversible voltammetry of ferrocyanide indicated slow electron transfer on titanium due to oxide formation.
    • Gold coating increased the electron transfer rate constant by ~80-fold, leading to reversible ferrocyanide voltammetry.
    • Gold-coated arrays showed 30-100 times higher ECL intensity compared to bare titanium arrays.

    Conclusions:

    • 3D printed titanium electrode arrays are feasible for electrochemical applications.
    • Gold coating is an effective strategy to enhance electron transfer kinetics and ECL performance.
    • The developed electrode arrays show potential for sensitive ECL-based detection.
