Polyaniline nanofibers have recently received much attention as sensors because they have many advantages over conventional films. In particular, we have designed polyaniline nanofiber sensors for toxic gases and have shown that they give much faster and larger responses due to their small fiber diameters and hi surfrice areas (2, 5, 13). Subsequently, others have used arrays of oriented polyaniline nanofibers 14) as well as single nanowires (7) to detect gases.
