We investigated direct writing properties of cobalt-based patterns in air using femtosecond laser reductive sintering of Co₃O₄ nanoparticles, and we applied for fabricating non-enzymatic glucose sensors. Co/CoO composite patterns were fabricated selectively on glass substrates by controlling pulse energy. Electrochemical properties of the Co/CoO composite electrodes in NaOH solution and D-glucose were evaluated. Glucose were detected using the electrodes without significant elution.
