Conformational Changes of Uniformly Charged Polyelectrolyte Chains on the Surface of a Polarized Gold Nanoparticle: Molecular Dynamics Simulation and the Theory of a Gaussian Chain in a Field

Modeling of Conformational Changes of Polyelectrolytes on the Surface of a Transversely Polarized Metal Nanowire in an External Electric Field

“…We can also note further prospects for such studies of conformational changes in adsorbed polyelectrolytes on the surfaces of gold nanoparticles. Of great interest, in addition to spherical [15][16][17] and cylindrical [18][19][20] nanoobjects, is the study of conformational rearrangements on the surface of spheroidal gold nanoparticles with different anisotropy in order to obtain nanosystems with tunable plasmon characteristics. On the surface of a prolate [21][22][23] or oblate spheroidal nanoparticle, both charged and polarized along the rotation axis, the distribution of electric charges differs significantly from the cases of charge distribution on the surface of polarized spherical or cylindrical nanoobjects.…”

“…Previously, the authors studied electrically induced conformational changes in macromolecular chains on the surface of gold nanoobjects of spherical [15][16][17] and cylindrical [18][19][20] shapes, as well as on the surface of gold prolate nanospheroids [21][22][23] and the flat surface of a gold crystal. It was shown that under the influence of both a static external electric field and microwave electromagnetic radiation, the conformational structure of polyelectrolyte chains adsorbed on the surface of metal nanoobjects changes significantly, and at the same time depends on the shape of the nanoobject.…”
