Eureka Nano

This document describes the Eureka Project E! 3892 Modpoleuv which aims to develop novel methods of modifying polymer surfaces for biomedical applications using extreme ultraviolet (EUV) radiation. The project has built a compact laser plasma EUV source based on a gas puff target for this technique. Studies show EUV irradiation improves the biocompatibility of polymers like PET by increasing cell alignment and adhesion compared to UV laser irradiation. The project has resulted in several publications on EUV-induced physical and chemical changes to polymer surfaces.
