Abstract

A membrane particularly for use in a sensor of the enzyme-electrode type which comprises one or more layers of material and an enzyme-containing layer and in which one layer is formed from a sulphonated or unsulphonated polyarylsulphone or a sulphonated or unsulphonated polyarylketone. The specification also relates to a non-enzymic sensor having a membrane including a layer formed from one of these polymers. Methods for determining an analyte using an enzymic or non-enzymic sensors are also included in the scope of the invention.
