Abstract
A multilayer analytical element has been prepared for accurate and rapid colorimetric determination of ethanol in aqueous specimens using alcohol dehydrogenase and an oxidized nicotinamide coenzyme. The element includes at least one reagent layer beneath a porous spreading layer. This reagent layer has a crosslinked polymeric binder prepared, in part, with a polymerizable monomer having a halomethylcarbonyl, haloethylcarbonyl, halomethylsulfonyl or haloethylsulfonyl group. Alcohol dehydrogenase is in a layer of the element for reaction with the analyte.
