Researchers of the Leibniz-Institut für Polymerforschung Dresden e.V. received the MaterialVital Award 2019 of the Federal Ministry of Science and Education (BMBF) within the ProMatLeben initiative.
Dr. Passant Atallah, Dr. Lucas Schirmer, Dr. Uwe Freudenberg and Prof. Dr. Carsten Werner from the Leibniz Institute of Polymer Research Dresden e.V. (IPF) received the award "Best Development in the Field of Polymers for the Health Sector - Largest Innovation Potential" of the ProMatLeben initiative of the Federal Ministry of Education and Research (BMBF) for the development of novel hydrogel wound dressings to treat chronic skin wounds. In Germany alone, there are currently more than 900,000 patients with chronic wound healing disorders who often also suffer from diabetes or cardiovascular diseases.
In cooperation with partners in the DFG Collaborative Research Centre Transregio 67 (Dr. Sandra Franz and Prof. Jan-Christoph Simon, University of Leipzig), the research team was able to develop polymer networks from derivatives of the glycosaminoglycan heparin and branched poly(ethylene glycol), which can absorb inflammation-promoting signal molecules from the wound like a "molecular sponge". The design of the polymer networks advantageously allows for retaining signal molecules that promote wound healing. Since the hydrogel wound dressing does not release bioactive substances, the new technology is expected to become quickly approved and translated into clinical application. For this purpose, a hydrogel-coated textile wound contact dressing has now been developed and successfully tested in a large animal model. The team of prizewinners is currently preparing the spin-off of a company.

Title: "Artificial Cell Membrane Platforms for Drug Discovery and Super Sensors"

15 million people worldwide suffer a stroke each year. To date, treatment options that reduce the consequential damage after a stroke are limited. A promising new approach targets the repair of the vascular system which entails the regeneration of brain tissue and leads to an amelioration of the corresponding body function. In this study, antibodies against Nogo-A, a growth-inhibiting molecule for nerve fibers as well as vessels, were applied to mice after a stroke. The blood vessels in these mice showed improved regenerative capacity, and they recovered affected motor skills better than those of the mice in the control group. To eliminate the impact of signaling from the surrounding tissue observed in in vivo studies, capillary network formation was furthermore investigated in a three dimensional culture of human umbilical vein vascular endothelial cells (HUVECs) in defined glycosaminglycan-starPEG-based hydrogels confirming the in vivo results. Antibodies against Nogo-A are already being used in a phase II study to treat patients with spinal cord injuries and could soon significantly benefit stroke patients as well.

Manfred Maitz (IBP) has been appointed as Guest-Professor (2019-2023)
at the "Southwest Jiaotong University in Chengdu", China.

The German Research Foundation (DFG) will support Alla Synytska (Polymer Interfaces, IPF) and Carsten Werner over the next three years to work on a new project titled „Amphiphilic Fouling-Resistant Surfaces Based on Janus particles”.

Alla Synytska, Jens Friedrichs and team will jointly explore a new, scalable design strategy for amphiphilic surfaces with controlled fouling resistance relying polymer-functionalized colloidal particles as surface-immobilized building blocks. The ability of the developed surfaces to inhibit adhesion of different bacterial species will be tested using high throughput bulk- as well as single cell-assays. The combination of these methods is expected to gain mechanistic insight in the anti-adhesive capabilites of amphiphilic surfaces.
