Abstract
The present invention provides a biosensor comprising an electrode and a membrane in which the biosensor includes at least two zones each zone differing from each other zone in a property. The membrane includes a plurality of ionophores, at least a proportion of which are capable of lateral diffusion within the membrane. A plurality of first binding partner molecules are attached to membrane elements positioned within a first zone such that the first binding partner molecules are prevented from diffusing laterally into a second zone. Second binding partner molecules are attached to the ionophores and the rate of lateral diffusion within the membrane of the first binding partner molecules and second binding partner molecules is different.
