Research object: protein and nucleic type nanostructures, protein molecule, electronic subsystem of proteins, nitrogen-oxygen model, protein-like nanowires, DNA molecule, polypeptide fragments of protein molecules, specific conductivity.
The purpose of the work: obtaining new knowledge about the responses of the investigated condensed mediums of organic origin to the action of electromagnetic fields and thermal influences in order to predict their physical properties, useful in the creation and application of sensors, in particular, sensors based on plasmon resonance, biosensors.
Research methods: theoretical and mathematical data analysis, comparison with experiment, analytical and numerical modeling.
The existence of a directed electrostatic field in a protein molecule in the absence of an external field has been established. It is related to the inhomogeneous nature of the system, which is due to the radicals in the amino acids that form the protein and provides the nanocurrent. It is shown that the primary structure of a protein molecule can be considered as a semiconductor nanowire.
The dependence of the calculated conduction states on the effective electrostatic field is analyzed. It is shown that with an increase in the magnitude of the field, the conduction states shift in the direction of decreasing energy.
A theoretical model of electron transfer through the conduction zone of protein-like nanowires under real temperature conditions has been constructed and substantiated.
The possibility of controlling the transfer of electrons along a protein-like nanowire as a component of the metabolic process was investigated. The influence of the magnetic field on the electron transfer along the protein nanowire is considered.
The conditions under which the influence of the magnetic field is positive and under which ATP synthesis can be blocked have been established.
