Surfactant Sensors in Biotechnology Part 2 - Non-Electrochemical Sensors

摘要: An overview on electrochemical surfactant sensors is given with special attention to work published since 1993. The importance of surfactants in modern biotechnology stressed out. Electrochemical are usually divided according the measured physical quantity potentiometric, amperometric, conductometric and impedimetric sensors. last ones very few. Potentiometric most numerous due their simplicity versatility. They can be used either as end-point titration or direct EMF measurement sensors, batch flow through mode. Some amperometric true biosensors using microorganisms living cells.
