Résumé : (Figure Presented) Poly (ethylene glycol) (PEG) films are known to be protein-repelling and to reduce biofilms attachment. We use a simple, easy to set up, versatile atmospheric pressure radiofrequency plasma to deposit plasma-polymerized polyethylene glycol) films onto polyvinylfluoride (PVF) and gold surfaces, using liquid or gaseous tetraglyme (CH3O(CH 2CH2O)4CH3) as precursor. The chemical composition of the films was studied using infrared reflection absorption spectroscopy, X-ray photoelectron spectroscopy and secondary ions mass spectroscopy. Bovine Serum Albumin adsorption has revealed good biocompatible properties that are correlated to the surface composition. © 2010 WILEY-VCH Verlag GmbH & Co.
