Mono-channel taste sensor using LB film

Mono-channel taste sensor using polyion-complex LB file is described. The sensing film deposited on the silver plate was dioctadecyldimethylammonium bromide (DOABr) combined by potassium polyvinyl sulfate (PVSK) as an under layer. New method was developed by detecting both parameters of membrane potential change and time response for titration. Five basic taste substances could be experimentally discriminate by these parameters.
