| Abstract: | Horseradish peroxidase (HRP) was incorporated into multiwalled carbon nanotube/thionine/Au (MTAu) composite film by electrostatic interactions between positively charged HRP and negatively charged MTAu composite. The results of electrochemical impedance spectroscopy (EIS) confirmed adsorption of HRP on the surface of MTAu modified GC electrode. Moreover, the electrochemical results showed that HRP retained its bioactivity and bioelectrocatalytical activity, and also showed good direct electron transfer behavior on such a composite film. |
