Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP and the Fraunhofer Institute for Silicon Technology ISIT have successfully developed and tested flexible electrochemical biosensors on metallized film substrates.   Fraunhofer FEP has the technology to provide polymer films with a thin metal layer, which is based on a roll-to-roll process. A high degree of uniformity of the layer‘s thickness and a lack of defects represent particular technological challenges ...
