| Abstract | Abstract : This paper introduces a new approach for designing chemical sensors. This approach is based on a concept borrowed from the membrane-based separations area - ultra thin film composite membranes. Ultrathin film composite membranes consist of an ultrathin (less than ca. 100 nm-thick) polymer skin coated onto the surface of a microporous support membrane. These composite membranes have made a tremendous impact on the field of membrane-based separations because they can offer high permeate flux without sacrificing chemical selectivity. These two qualifies (high permeate flux and high chemical selectivity) are also required in polymeric barrier layers in chemical sensors. Therefore, the ultrathin film composite membrane concept should be applicable to sensor design. In this paper we present proof of this concept by showing the response characteristics of a prototype glucose sensor based on an ultrathin film composite membrane. |
