Study of charge transfer process in system of «hemoglobin-electrode» at level of individual molecules
The process of electron transfer through an individual hemoglobin molecule (Hb) has been studied by conductive atomic force microscopy. It is shown that the current through the Hb molecule arises at applied force equal 45 nN. According to estimates, the height of the deformed molecule is 4,5 nm....

| description | The process of electron transfer through an individual hemoglobin
molecule (Hb) has been studied by conductive atomic force
microscopy. It is shown that the current through the Hb molecule
arises at applied force equal 45 nN. According to estimates, the
height of the deformed molecule is 4,5 nm. Based on the analysis
of the experimental I-V characteristic of the probe/Hb/substrate
contact using of the non-resonant tunneling transport model, the
parameters of tunnel electron transport through the individual Hb
molecule are determined. |
