Abstract
Chemical sensors using Langmuir-Blodgett (LB) films have been reviewed. After chemical sensors are classified according to the types of transducing devices and the kinds of analytes in gas or liquid, the sensors with LB films already reported are described. Subsequently, gas sensors, biosensors, and odor sensors are discussed on their materials, deposition conditions and resultant characteristics, etc. The detailed descriptions have been given to the glucose sensors with glucose-oxidaseimmobilized LB films, and it is demonstrated that partially decoiled enzyme molecules can be more efficiently and stably adsorbed onto the monolayer, and more suitable for biosensor fabrication than non-denatured molecules.
