Paper Abstract

Ion channels are promising biomolecules for sensor applications. They combine high sensitivity with excellent selectivity. Presently the main problem consists in the integration of such ion channels into synthetic matrices but keeping them operative. In this study we report on the development of a microstructured polymer layer as matrix for an ion channel sensor array and an optical method for parallel detection. A thin PMMA layer was prepared by spin coating a gold surface. Small pores with diameter in the range of few micrometers were made by e-beam lithography. FTIR imaging spectroscopy and SPR imaging were used to characterize the quality of microstructured arrays.
