Abstract :
Describes a measurement method to detect ppm level of noncharged agricultural chemicals using a lipid/polymer membrane sensor within five minutes. In the case of this new measurement method, non-charged toxic substances are detected indirectly. Sensor output is change of membrane potential caused by interaction among lipid membrane, agricultural chemicals and lipid in a solution. This, method has a possibility of detection of a trace amount of agricultural chemicals. It is useful for the evaluation of safety of vegetables and fruits.
