| Abstract: | Hemoglobin(Hb) immobilized on the surface of the poly(methelene blue)-multi-walled carbon nanotube modified glassy carbon electrode(Hb/PMB-MWNTs/GCE) can undergo effective and stable direct electron transfer reaction.A H2O2 biosensor based on hemoglobin/poly(methelene blue)-multi-walled carbon nanotubes polymer film modified electrode was prepared.The electrochemical behavior of the modified electrode was investigated.Hb on the H2O2 biosensor can carry out persistent and direct electron transfer reaction,an... |
