BIOSENSOR UTILIZING CARBON NANOTUBE

摘要

Disclosed is a biosensor having a detection electrode, wherein the material for the detection electrode is a boron-containing carbon nanotube (CNT). In the biosensor, the detection electrode is formed, for example, by mixing the boron-containing CNT with a mineral oil, an ionic liquid or a polymeric binder resin to produce a paste-like material and filling the paste-like material into a cylindrical container. The biosensor can detect a substance contained in a sample without being affected by any electrochemically active substance including a reductive interfering substance, can improve the detection sensitivity for the substance, and has a simplified construction.
