Abstract

In this paper we present a method for the integration of porous track‐membranes into silicone based microfluidic devices. It is based on a surface modification of the membranes which enables us bonding it to silicone using a glue‐free plasma bonding process. The membrane can be structured into permeable and impermeable regions on a sub‐10 μm scale. This is achieved by combining polymer imprinting with a layer transfer technique. The membrane is characterized and a direct current microelectrode array is presented as an application example. (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
