The Mirica Laboratory has developed an exceedingly simple and rapid approach for integrating conductive nanorods of metal organic frameworks (MOFs) into chemiresistive devices on polymeric substrates. This approach involves fabricating thermally miniaturized interdigitated electrodes by drawing graphite wires with a commercial HB pencil on shrinkable polymeric films. Templated growth of MOFs from solution directly into this device architecture produces functional chemiresistive gas sensors from modular molecular building blocks. The resulting devices are capable of detecting and differentiating ammonia, nitric oxide, and hydrogen sulfide gases at ppm concentrations.
