Direct electron transfer has also been achieved with many metalloproteins such as cytochrome C, horseradish peroxidase, microperoxidase (MP-11), myoglobin, hemoglobin, catalase, azurin, and so on, immobilized on different CNT-modified electrodes [45, 61, 144—153].

Liu et al. have demonstrated that the direct electron transfer reactivity of the immobilized hemoglobin (Hb) can be effectively enhanced by the addition of MWNTs into the PUE film (118). Biosensors based on the direct electron transfer of the immobilized proteins show good analytical performance, including high sensitivity, acceptable fabrication reproducibility, and storage stability.
