| Zusammenfassung: | A process for preparing polyvinyl alcohol grafted 4-vinylpyridine features that polyvinyl alcohol is used as initial substance. It includes such steps as triggering by cemmonium cerium nitrate, graftpolymerization of 4-vinylpyridine in acidic aqueous solution, deposition with formyl and vacuum drying. its advantages are easily available raw materials, low cost, and simple process. Said product as carrier benefits the fixation of enzyme. The enzyme-containing aqueous solution of grafted product can be directly dropped onto surface of electrode to prepare biosensor. |
