The SWNTs/DDAB film modified glassy carbon electrode was successfully prepared to study the electrochemical behavior of hemoglobin (Hb). A better electrochemical response was observed than that on the DDAB or SWNTs film modified electrode. Cyclic voltammetry of Hb showed two pairs of well‐defined and nearly reversible peaks. The electrochemical reaction of hemoglobin on the SWNTs/DDAB film modified electrode was controlled by absorption. Using the SWNTs/DDAB film modified electrode, the interaction between hemoglobin and tar was studied.
