In this paper, carbon nanotubes–hydroxyapatite (MWCNTs–HA) composite were synthesized by self-assembling technique, and investigated by X-ray diffraction, scanning electron microscopy (SEM) and FT-IR spectroscopy. Hemoglobin (Hb) immobilized in MWCNTs–HA film not only retained its similarly native conformations, but also achieved the direct electron transfer. The apparent heterogeneous electron transfer...
This study described the bioelectrochemistry of hemoglobin (Hb) at multiwall carbon nanotubes (MWCNTs) noncovalently functionalized with biopolymers of sodium alginate (SA). The characteristics of Hb/SA–MWCNTs composite film were studied by using FT-IR spectroscopy, UV–vis spectroscopy and electrochemical methods. Hb immobilized on SA–MWCNTs composite film retained its native secondary structure,...
