Degradable block copolymers have shown great potential to combine transfection capability with low toxicity of the transfection agent. Depsipeptide blocks exhibiting strong physical interactions were conjugated with PEI moieties to di and triblock copolymers. Upon nanoparticle formation and complexation with DNA, the resulting polyplexes (sizes typically 60-150 nm) showed remarkable stability compared to PEIonly or lipoplex, and facilitated efficient gene delivery. These nanocarriers form the basis for a delivery platform-technology especially for gene transfer to primary human cells. more
Current polymeric actuators move because of their continuous response to the input signals of the controlling unit and cannot be interrupted without stopping or eliminating the input trigger. The new type of non-continuously responding actuator materials are capable of pausing their movements in a defined manner upon continuous cyclic heating and cooling. more

This year’s 12th International Conference Polymers for Advanced Technologies-PAT 2013, organized by the Institute of Biomaterial Science, Helmholtz-Zentrum Geesthacht (HZG), will be held in Berlin from 29 September to 2 October 2013. With more than 300 presentations this event figures worldwide to be one of the most important congresses on polymer research. more
On Friday September 27th the opening event of the Helmholtz Graduate School for Macromolecular Bioscience will take place at the Free University of Berlin. Following welcoming words from the Scientific Director of the Helmholtz-Zentrum Geesthacht Prof. Dr. Wolfgang Kaysser and greetings from politics and science, the participants will get a brief introduction of the scientific work. more
Biomaterial researchers in Teltow have developed plastics that can repeatedly change from one shape to another and then back again when temperatures fluctuate within a selected range. The material, dubbed “polymer actuators” by its creators, thus overcomes a major limitation that affects similar materials. Up until now, polymers with temperature-controlled shape memory could only change form once. more
Am 12. Dezember 2011 um 18 Uhr wird das neue Forschungsgebäude des Zentrums für Biomaterialentwicklung des Helmholtz-Zentrums Geesthacht seiner Bestimmung übergeben. Mit rund 2000 Quadratmetern Nutzfläche bietet der Erweiterungsbau Raum für neue Laboratorien und Büros. Um die Entwicklung neuartiger, kunststoff-basierter Materialien voranzubringen, werden hier insbesondere Sterilisationstechniken, neuartige Wirkstoff-Materialkombinationen und der Aufbau von Makromolekül-Bibliotheken Gegenstand der Forschung sein.
