Abstract
Environmental discharge is a global problem. Among many others, the Water Industries seek new broad sreening devices able to provide early warning of toxic discharge at presently “unprotected” sites. The search for broad screening presents different problems to the detection of a specific known analyte and screening procedures with a broad specificity must be chosen. This paper describes a broad band screen for herbicides active on the photosynthetic system and explores whether analysis of the signal detail can give more information about the analyte. It also looks critically at the construction of a biosensor which would use this photoelectrochemical mechanism, employing a reagent phase immobilised next to an electrode and debates the possibility of other formats. An inverted format sensor is then exploited to devise a single analyte sensor specific for formaldehyde monitoring in the gas phase and operational over an eight hour work shift period.
