FIELD: physics.
SUBSTANCE: solution for dielectrophoresis with selected molecules and/or particles (up to nanometer dimensions) is taken in form of liquid film 5 nm - 10 micron thick. Electromagnetic field heterogeneousness points required for dielectrophoresis are formed near ends of surface-active molecules, being in surface mono-molecular layers of liquid film, by targeting film from side or upwards at sliding angle less than 20 degrees by laser radiation for effecting molecules and particles in selective way, controlled by forming of distinctive long narrow light channels in the film.
EFFECT: higher efficiency.
