| Abstract: | The molecular dynamics method has been used to study the rearrangement of the conformational structure of polyampholytes adsorbed on the surface of a prolate spheroidal metal nanoparticle with a periodic change at a microwave frequency of its polarity along the major axis. An analytical model is proposed for the quasi-equilibrium structure of an adsorbed macrochain in the alternating electric field. At a low temperature, the formation of an annular macromolecular fringe was observed in the equatorial region of the nanospheroid, the width of which depended on the amplitude of the polarizing external alternating electric field. At a high temperature, depending on the distance between oppositely charged units in the macrochain, either changes in the shape of the macromolecular fringe from densely enveloping the entire nanospheroid to a dumbbell-shaped fringe twice during the oscillation period or the formation of a macromolecular ring around the nanospheroid was observed.
