A theory of hole, exciton and impurity states in QDs, which are affected by electric and magnetic fields and interact with biological objects (blood albumin molecules), has been developed. Within the framework of the developed model, regularities of changes in the absorption coefficient and lifetime of an electron and a hole in excited states have been established depending on the location of the acceptor or neutral impurity in the core/shell QDs and in the QD–HSA bionanocomplex, as well as on the magnitude and direction of the electric field and the structure of the QD shell. Regularities of changes in the energy spectrum of electrons and holes in QDs and the QD–HSA bionanocomplex in the presence of impurities of various types under the influence of a magnetic field have been established. A mathematical model of a spherical A2B6 quantum dot with an impurity in a magnetic field and interacting with adsorbed protein molecules was constructed. Within the framework of the developed model, the effect of a uniform magnetic field on the energy spectrum of an electron, hole, and exciton in the bionanocomplex “semiconductor quantum dot CdTe – human serum albumin” was investigated. The proposed model takes into account polarization effects caused by the dipole potential of the protein shell, as well as spin splitting in a magnetic field. The regularities of change in the energy of quasiparticles depending on the radius of the quantum dot (undoped and with a donor or acceptor impurity), the concentration of albumin, and the magnitude of the magnetic field induction were established.
