Abstract: A chemical sensor selectively detects an analyte in a solution. The sensor comprises a flow-through chamber, a selective membrane, a transducer, an inlet for a liquid flow containing a recognition element, and an outlet. To detect an analyte in a solution, a recognition element is contacted with the solution containing the analyte via a selective membrane. This results in a response detectable by a transducer. The recognition element is injected into a flow, and the flow is passed into a flow-through chamber comprising the transducer and the selective membrane, where it contacts the analyte passing from the solution outside the chamber. The recognition element and the analyte interact to provide a signal that is detected by the transducer. The chemical sensor is used for detecting analyte(s) in a reactor system, a flow system or in an in vivo system.
