Under the auspices of INM — Leibniz Institute for New Materials, scientists are working on coating processes that smooth the tube walls and make them well tolerated for the human body. The kick-off meeting of the joint project Nano4stent took place at the beginning of January, bringing together the partners of INM, the Saarland University Hospital Homburg, the Kocaeli University/Turkey, and the Korean University of Technology and Education/Korea.
The scientific experts use a special method in their research work: In the same way as water drops from vapor are formed uniformly on the cold lid of a pot, the researchers form the coating on the surface of the tube. "It is our aim to cover the surface of the tubes with a completely even protection layer", says Cenk Aktas, head of the program division "CVD/Biosurfaces". For this purpose, small cavities will be applied synthetically on the surface by using laser treatment. After each cavity and the whole surface of the tubes is perfectly coated, the unwanted components will no longer have a chance to react with the surface of the tube and to adhere there.
The research is focused on development of materials – for today, tomorrow and the future. From molecule to pilot production, they researchers follow the recurring question: Which material properties are new, how can they be investigated and how can they be used in the future?
