Enzymatic biosensors and methods of producing distal tips for biosensor transducers for use in detecting one or more analytes selected from organic compounds susceptible to dehalogenation, organic compounds susceptible to oxygenation and organophosphate compounds susceptible to hydrolysis are disclosed herein, as well as biosensor arrays, methods of detecting and quantifying analytes within a mixture, and devices and methods for delivering reagents to enzymes disposed within the distal tip of a biosensor.

Enzymatic biosensors with enhanced activity retention for detection of organic compounds

A sensor for measuring an oxygen content in a liquid or gaseous sample has first and second sensor sections (). The first sensor section () can be brought into contact with the sample and has a luminescent indicator dye embedded in an oxygen-permeable first polymer matrix. The second sensor section () is arranged adjacent to the first sensor section () and includes the same dye embedded in an oxygen-impermeable second polymer matrix. A light guide () guides luminescence excitation light from a light source () to the sensor sections () and guides luminescence emission light from the sensor section () to a detector ().
