Conteúdo: |
The present work deals with cold plasma organosilicon treatment of glass powder surfaces. The treated material underwent subsequent chemical derivations by storing samples inside an evacuated chamber, allowing chemical penetration at controlled pressures. The radicaIs' inductions were characterized by XPS within each stage of modification. The enzyme peroxidase was immobilized using functionalized materiaIs to check the resultant biocompatibility. A sequence of surface tailoring is proposed suggesting the anchoring of enzyme via C = O groups implanted on the glass surface. The experimental results demonstrate that the proposed process is suitable for the functionalization of materiaIs with irregular shapes.
