| Research Abstract |
A cationic surfactant ion-sensitive field-effect transistor (cationic surfactant-FET) and an anionic surfactant-FET have been developed. The cationic surfactant-FET shows an almost Nernstian response to tetradecyldimethylbenzylammonium chloride over a concentration range between 1.0x10^<-6> M and 1.0x10^<-3> M, with a slope of 58.5±1.7 mV/decade. The anionic surfactant-FET shows an almost Nernstian response to sodium dodecylbenzenesulfonate in the concentration range from 1.0x10^<-6> M to 1.0x10^<-3> M with a slope of 56.6±3.3 mV/decade. Microfluidic polymer chips were integrated with the cationic surfactant-FET or anionic surfactant-FET. These were fabricated using polystyrene plates and stainless wires as a template for the channel. The microfluidic polymer chip with embedded the cationic surfactant-FET detector or the anionic surfactant-FET detector was applied to a sequential injection analysis and a capillary electrophoresis of cationic and anionic surfactants.
