The development on novel materials is directed to on novel battery-electrodes, drug-release systems, stress-sensing-1 and (bio)-degradable soft/hard interfaces. Three dimensional (3D)-printing technology has become societies leading method to form materials for many applications. Prominent examples are the 3D- printing of self-healing polymer systems, pharmaceutical delivery materials and capsule-based multicomponent materials. Printing biodegradable polymers, capsules and materials for triggered time-release with defined long term delivery profiles represents an important challenge, currently addressed by proper design and synthesis of 3D-printable (co)-polyesters. We use multimode 3D-printing methods to prepare modern materials, with embedded self-healing-, mechanochromic- and pharmaceutical function.2

Delivery of pharmaceutical cargo as nanosized particles, vesicles or aggregates has become a prominent and medical useful endeavor.3-4 Polymers and lipids, equipped with modern STEALTH-technology are particularly interesting in this context, termed vesicles or polymersomes.5-13 Especially in view of site-specific delivery and imaging technology small, STEALTH-like particles with embedded functionalities are important, mediating both, biocompatibility and delivery of drugs, dyes and recognition sites. Based on our longstanding experience on artificial and biological membranes,3-4, 9, 14 we are currently developing ultra-small nanoparticles for high resolution imaging technology. Polymeric carrier-molecules consisting of a single chain are used in photoacoustic spectroscopy, displaying prolonged circulation times and excellent imaging properties.
