| 摘要 | Microporous poly(vinylidene fluoride) (PVDF) membranes with different porous surface morphologies were prepared by immersion-precipitation from coagulation baths of different strengths. On these membranes single-strand deoxyribonucleic acid (ss-DNA) was covalently immobilized by a dual-step procedure. First, poly(glycidyl methacrylate) (PGMA) was grafted on PVDF membranes by plasma-induced free radical polymerization. Then, ss-DNA was bonded to PGMA through ring-opening reactions of epoxies with amine to form amino alcohols. The highest attainable graft yield of PGMA on PVDF membrane was 0.3 mg/cm2, which was the case when a highly porous PVDF membrane was employed as the substrate. For immobilization of ss-DNA, the yield was found to depend significantly on the reaction temperature and pH. The maximal value was 48.5 μg/cm2. Furthermore, adsorption tests of anti-DNA antibody were carried out on membranes with and without immobilized ss-DNA using serum obtained from systemic lupus erythematosus patients. The results indicated that the immobilized DNA could effectively adsorb the antibody in the serum. |
