MARTINEZ-MANCERA, Flavio Dolores y HERNANDEZ-LOPEZ, José Luis. In vitro Observation of Direct Electron Transfer of Human Haemoglobin Molecules on glass/tin-doped Indium Oxide Electrodes. J. Mex. Chem. Soc [online]. 2015, vol.59, n.4, pp.302-307. ISSN 1870-249X.
Electron transfer properties of the haem (FeIII/FeII) redox center, in human haemoglobin molecules, were investigated, in vitro, on glass/tin-doped indium oxide electrodes. The total surface concentration of electrochemically active haemoglobin molecules corresponded to a single protein monolayer. In addition, anodic and cathodic peak currents changed in direct proportion with the scan rate, suggesting a surface-controlled electrode process.
