High-Throughput Nanoparticle Chemisorption Printing of Chemical Sensors with High-Wiring-Density Electrodes
We report on the high-throughput non-lithographic microprinting of a high-wiring-density interdigitated array electrode (line and space = 5 µm/5 µm), based on a facile wet/dewet patterning of silver nanoparticle ink. The trade-off between high-density wiring and pattern collapse in the wet/dewet pat...

| Summary: | We report on the high-throughput non-lithographic microprinting of a high-wiring-density interdigitated array electrode (line and space = 5 µm/5 µm), based on a facile wet/dewet patterning of silver nanoparticle ink. The trade-off between high-density wiring and pattern collapse in the wet/dewet patterning is overcome by employing a new herringbone design of interdigitated array electrode. We demonstrate electrochemical sensing of <i>p</i>-benzoquinone by the fabricated interdigitated array electrode, showing a typical steady-state <i>I</i>–<i>V</i> characteristics with superior signal amplification benefiting from the redox cycling effect. Our findings provide a new technical solution for the scalable manufacture of advanced chemical sensors, with an economy of scale that cannot be realized by other techniques. |
