Abstract (in Japanese) (See Japanese page) 
(in English) We report on an electrochemical sensor that is based on carbon nanotubes (CNT) and plasma-polymerized film (PPF). The CNTs were sandwiched with 2 nm-thick acetonitrile PPFs. Under PPF layer was deposited onto sputtered gold electrode. Neutral red (ND) as a electron transfer mediator was positioned between under PPF layer and CNT layer. We optimized the CNT and ND concentration for casting formation onto the under PPF layer. The nicotin adenine dinucleotide (NADH) sensor showed highsensitivity (a sensitivity of 29 &#61549;A mM-1 cm-2, a correlation coefficient of 0.991, a linear response range of 0.3-4.2 mM, +0.15 V vs Ag/AgCl), and rapid response (< 7s in reaching 95% of maximum response). This high performance is attributed that CNTs offer excellent electrocatalytic activity and enhance electron transfer. This potential at +0.15 V also detected ascorbic acid which is the interferant agent. Then, the potential at -0.20 V completely eliminated the signal due to the ascorbic acid, though the sensitivity toward the target was bit lower than that at +0.15 V.
