An analyte is then placed in fluidic connection with the probe molecule on the surface. The silicone oil phase contains less than about 5% by weight of the emulsion of a non-volatile oil and includes about 2% to about 25% by weight of the emulsion of a volatile linear silicone. The ion-complexing material layer is arranged between the anode and the cathode.
