• We have developed a simple and inexpensive method to fabricate carbon nanotube-based chemical sensors by fabricating a horizontally aligned carbon nanotube film on a titanium/gold-coated glass plate using electrophoresis and fissure formation techniques. The sensors exhibited low noise and thus high sensitivity to the NH 3 and NO 2 molecules and the response times were relatively short. They were completely recovered within 40 s when a dc voltage of 5 V was applied for less than 30 s. The fabrication processes do not require any expensive equipment like e-beam lithographs. They are relatively simple and low-cost, and the sensors themselves are mass-producible.
