Someone suffers second- or third-degree burns: The wound must immediately be dressed and the dressing is to be changed regularly.
A short movie made by the group of Prof. Dr.-Ing. Stephan Barcikowski (University of Duisburg-Essen) shows the development of a dressing that promotes wound healing – from the materials research laboratory until the first practical trial (in English).
Even small area burns can be delicate, because healthy skin is our largest and most effective barrier against pathogens. It is therefore essential to support the wound healing process and to fight germs at the same time. Some metal ions, such as zinc or iron are known to accelerate healing.
Currently, the challenge for research is to develop an appropriate substrate to release the active ingredients gradually. In addition, it must be ensured that the active ingredients are harmful to bacteria but harmless to the human body.
Technical Chemist Nina Million from University of Duisburg-Essen (UDE) has developed a wound dressing containing nano zinc during her master thesis and was awarded the prize for the best thesis in 2013 by the German Society for Biomaterials. She removed zinc oxide and iron oxide nanoparticles from solid targets by laser pulses and applied them in a sponge-like carrier material.
This so-called microgel is arranged like a network enclosing the particles. Applied to a wound, it gradually releases antibacterial ions, while the particles themselves remain inside the microgel. Recently, studies adjusting the dose and thus optimizing the composition were successfully completed on rats.
The development succeeded in collaboration with the DWI – Leibniz Institute for Interactive Materials in Aachen and Hannover Medical School. An approximately four-minute movie produced together with the “Beilstein Institute zur Förderung der Chemischen Wissenschaften“ in Frankfurt clearly reconstructs the development process – in terms of interviews, laboratory demonstrations and explanatory drawings.
"It was fun to make this film," says Million. "But I also realized how difficult it is to summarize and communicate our own research in just a few words."
She can be proud of the result „Laser rapid prototyping of bioactive materials for medical treatment“ (in English):

Researchers in the Cockrell School of Engineering at The University of Texas at Austin are one step closer to delivering smart windows with a new level of energy efficiency, engineering materials that allow windows to reveal light without transferring heat and, conversely, to block light while allowing heat transmission, as described in two new research papers.
By allowing indoor occupants to more precisely control the energy and sunlight passing through a window, the new materials could significantly reduce costs for...
Argonne scientists used Mira to identify and improve a new mechanism for eliminating friction, which fed into the development of a hybrid material that exhibited superlubricity at the macroscale for the first time. Argonne Leadership Computing Facility (ALCF) researchers helped enable the groundbreaking simulations by overcoming a performance bottleneck that doubled the speed of the team's code.
While reviewing the simulation results of a promising new lubricant material, Argonne researcher Sanket Deshmukh stumbled upon a phenomenon that had never been...
