Plasma-based surface modification for life-science applications — •Katja Fricke and Klaus-Dieter Weltmann — Leibniz Institute for Plasma Science and Technology e.V. (INP), Felix-Hausdorff-Strasse 2, 17489 Greifswald, Germany

Materials with tailored chemical and morphological properties provide an indispensable platform to induce a certain response when exposed to biological systems. Hence, bioactive surfaces are of growing interest for a vast number of applications such as biochips, biosensors, drug delivery systems, implants and tissue engineering. Plasma enhanced surface modifications are the key applications for plasma technology since decades. Due to the fact that these processes are environment-friendly, highly reproducible, and most importantly, enable changes in surface properties for nearly every material. Furthermore, the high flexibility in terms of geometry and electrode configuration, process gases and operation parameters, qualify both, low-pressure and atmospheric-pressure plasma sources especially for surface engineering. This contribution reports on the plasma-based surface modification to improve the attachment of bioactive compounds and living cells. Recent innovations in the functionalization of surfaces and the deposition of high-quality functional thin films by using atmospheric-pressure plasma processes are presented.
