Abstract
A composition comprising an immobilized biological membrane is provided. The functional immobilized biological membrane consists of a support structure, a metal layered onto a surface of the support structure, an alkanethiol monolayer assembled onto the metal, and a biological membrane deposited on the alkanethiol monolayer. Also provided is a method of producing the immobilized biological membrane, wherein the method involves contacting an alkanethiol with a metal surface of a support structure in forming an alkanethiol monolayer assembled onto the metal, and depositing a biological membrane onto the alkanethiol monolayer such that the biological membrane becomes associated with the alkanethiol monolayer. Uses of the biological membrane include as a sensing indicator in a biosensor, as an adsorbent in a chromatography system, and as a coating for medical devices.

17. A method of detecting a reactant in a sample suspected of containing the reactant, comprising the steps of:
-
(a) contacting the immobilized biological membrane of claim with the sample, wherein the immobilized biological membrane has at least one component which reacts with the reactant to be detected; and (b) measuring a change in the activity of the component as an indicator of the presence or absence of the reactant.
