Herein disclosed are biosensing systems that measure lactose concentration in a solution.

Biosensing systems for measurement of lactose

A waveguide sensor capable of direct, real-time detection and monitoring of analytes in the vicinity of the waveguide surface without requiring the tagging or labeling of the analyte, is described. Analytic and numerical calculations have predicted that by locally detecting either changes in the evanescent field or changes in the light coupled out of the waveguide as a result of the presence of the analyte, high detection sensitivity will be able to be achieved.

Optical analyte sensor

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.
