    Abstract

    PDMS microstructures whose whole inner surfaces are covered with perfluoro polymer are described. The major problems of PDMS microfluidic devices in Micro Total Analysis Systems (µTAS) applications are surface degradation with organic solvents and unexpected adsorption of chemical materials. In order to overcome these problems, perfluoro amorphous polymer is coated on the PDMS micro structures. This method is useful to realize chemical durability of the PDMS microfluidic devices. And novel method for fabricating metal electrodes on the perfluoro polymer is also proposed.
