|Title:||Effect of toluene extraction on BiomerTM surface: I- ESCA, ATR/FTIR, contact angle analysis and biological properties||Authors:||N., Nurdin

|Issue Date:||1995||Project:||None||Journal:||JOURNAL OF BIOMATERIALS SCIENCE POLYMER EDITION||Abstract:||
Biomer is a poly(ether-urethane-urea) block copolymer widely used as biomedical devices. Extraction process of this polymer has purified its surface of low molecular weight polyurethane chains and Santowhite Powder additive. ESCA and ATR/FTIR have suggested a homogenization of the polymer by enrichment of the first layers with poly(aminomethacrylate) additive after extraction. Therefore, the surface of the extracted Biomer exhibits a different wettability and biological response. The treatment causes a significant decrease in fibronectin adsorption and induces a reduction in Staphylococcus aureus adhesion.
