Abstract

12 In recent years, we have developed the eco-sensor, which means the sensor for the measurement of environmental pollutants, based on lipid membranes for continuous monitoring of underground water in industry areas such as semiconductor factories. In order to improve the stability and the responsibility of bilayer lipid membranes (BLMs) in the eco-sensor, we have investigated both the stabilization of BLMs based on the supporting structure and the test making of the automatic BLMs preparation device. The application of the supporting structure using gelatin, etc showed the some times' extension of the BLMs life. But the decrease in the sensitivity of the sensor was observed in the storage of the sensor. An automatic BLMs preparation device was made by use of an inkjet mechanism. The reproducibility of the BLMs preparation was remarkably improved. The sensitivity to organochlorine compounds was in the order of 10 ppb using the monoolein BLMs.
