Porphyrin-filled nanofibrous membranes were facilely prepared by electrospinning of the mixtures of poly(acryionitrile-co-acrylie acid)(PANCAA) and porphyrins. 5,10,15,20-Tetraphenyiporphyrin(TPP) and its metalloderivatives(ZnTPP and CuTPP) were studied as filling mediators for the immobilization of redox enzyme. Results indicate that the introduction of TPP, ZnTPP and CuTPP improves the retention activity of the immobilized catalase.Among these three porphyrins, the ZnTPP-filled PANCAA nanofibrous membrane exhibits an activity retention of93%, which is an exciting improvement. This improvement is attributed to both the strong catalase-porphyrin affinity and the possible facilitated electron transfer induced by the porphyrin as evidenced by quartz crystal microbalance (QCM) and fluorescence spectroscopy studies.
