Micro- and Nanostructured Microfluidic Devices for Localized Protein Immobilization and Other Biomedical Applications (Schriften des Instituts fuer ... Institut fuer Technologie ) (Volume 29)

A new immobilization method for the localized adsorption of proteins on thermoplastic surfaces is introduced. Artificial three-phase interfaces were realized by surface structuring to control the wetting behavior which lead to a preferred adsorption in these modified areas. Additionally, different fabrication methods were analyzed to determine mass fabrication capabilities. These fabrication methods also allowed the production of fully structured microchannels to tune the fluids behavior within.
