direct transfer
7.The author studied and compared the method of fabricating the MWCNT-Nafion/CAT electrode through immobilizing catalase in the MWCNT-Nafion film,finding that MWCNT immobilized in Nafion film can effectively accelerate electron transfer between CAT and the surface of glassy carbon electrode(GCE) and realize direct electron transfer of CAT on the MWCNT modified electrode.
