Laser patterning and modification of polymers for cell culture applications
Dr. Wilhelm Pfleging, Institute for Materials Research, Forschungszentrum Karlsruhe (FZK)
Two types of laser patterning are of interest for application in microsystem technology: direct ablation of polymer material for the generation of two or three dimensional shapes such as microfluidic channels or micro-holes and photo-induced changes of chemical or physical properties. An appropriate choice of laser and process parameters enables new approaches for the fabrication of lab-on-chip devices with integrated functionalities. Current research results in laser-assisted ablation and UV-modification of polymers will be presented with emphasis on polystyrene and the fabrication of polymer devices for cell culture applications
