A hydrogel is formed by a reaction which is induced, in an electrolytic solution, by an electrode product electrochemically generated by electrodes installed in the electrolytic solution. An apparatus including an electrolytic tank with a bottom surface on which a two-dimensional array of working electrodes is provided and a counter electrode installed in the electrolytic tank is prepared. An electrolytic solution containing a dissolved substance that causes electrolytic deposition of a hydrogel is housed in the electrolytic tank. By applying a predetermined voltage to one or more selected working electrodes of the two-dimensional array, a hydrogel with a two-dimensional pattern corresponding to the arrangement of the selected working electrodes is formed.

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.
