Nanoparticle(NP)-decorated carbon nanotube (CNT) ropes used as sensing elements for hydrogen gas (H.sub.2) chemiresistors are described herein. The NP-decorated CNT rope sensors were prepared by dielectrophoretic deposition of a single semiconducting CNT rope followed by the electrodeposition of metal nanoparticles to highly disperse said nanoparticles on the CNT surfaces. The rope sensors produced a relative resistance change 20-30 times larger than what was observed at single, pure Pd nanowires. Thus, the rope sensors improved upon all H.sub.2 sensing metrics (speed, dynamic range, and limit-of-detection) relative to single Pd nanowires.
