Functional Membranes with Molecular Recognition. Applications to Biosensors.

Design concepts and fabrication technologies of functional membranes with molecular recognition are reviewed along with these applications to biosensors. Novel enzyme membranes have been disigned to recognize specifically their corresponding substrates and transfer electrons to electrodes through various molecular interfaces such as electron mediators and conducting polymers. These enzyme membranes are applied to fabricate new biosensors. Technology has also developed to assemble anti-body in a membrane form. Antibody membranes are applied to fabricate immunosensors.
