The current development in medical engineering induces new demands on materials. Polymers with specific surface treatment are used in new fields of application. A combination of convenient sensor technologies opens new investigation opportunities in cell culture technology. The focus of this work is to determine a set of suitable parameters for the surface modification of polymers by excimer laser irradiation and the effect on cellular growth. Polystyrene slides were pretreated in a developed functionalizing chamber by means of excimer laser irradiation in different reactive gas atmospheres. The results show that directed cell growth and adhesion can be influenced with the presented methods.
