Abstract

We investigate stochastic resonance in artificial ion channels inserted in bilipid membranes with varying membrane diameters. Stochastic resonance (SR) is fundamental for sensory reception of organisms, cell systems, single cells and bundles of ion channels. This indicates the importance of SR for applications in systems, such as nano scale single molecular biosensors. For Alamethicin, a standard ion channel model system, SR was found for large membrane patches. It was suggested that noise stemming from individual ion channels may affect collective properties of the whole ensemble. From the data obtained we find that a finite membrane size is required for SR.
