摘要： The present invention provides an electrochemical sensor having a solid electrically conductive substrate and a compound immobilized thereon which has binding affinity for an analyte species to be detected and also displays electrochemical behavior which is modified upon binding of that analyte species, so that binding of an analyte species can be detected by measuring electrochemical properties, such as by voltammetry. Desirably the immobilized compound contains both a first moiety with binding affinity for the analyte and a separate second moiety which is a redox system whose electrochemical oxidation/reduction properties become modified when the first moiety binds the analyte. The analyte binding moiety may be a diol or polyol and preferably is a sugar. The electrochemical sensor finds use in methods of analyzing reservoir and process fluids, particularly at a subterranean location. The electrochemical sensor may be a component of a downhole tool, adapted for deployment downhole.
