The combination of electrochemical, optical, acoustical and other measurement techniques with the specificity of biological recognition systems has resulted in a range of new analytical devices known as biosensors. Biosensors are under intensive development worldwide because they have a multitude of potential applications, in particular, clinical medicine, environmental monitoring and process control of industrial processes. Their basic principles, mode of operation, performance requirements and current trends will be reviewed. A brief description of a novel biosensor developed at Lincoln Technology, the MICREDOX method, is outlined and applications for rapid measurement of biochemical oxygen demand and toxicity measurements are described. Preliminary data obtained using the MICREDOX method are reported for three standard toxic materials, zinc sulphate, 3,5-dichlorophenol and sodium lauryl sulphate.
