摘要: Confinement is a versatile and well-established tool to study the properties of polymers either understand biological processes or develop new nanobiomaterials. We investigate conformations semiflexible polymer ring in weak spherical confinement imposed by an impenetrable shell. analytic argument for dominating trajectory depending on flexibility considering elastic entropic contributions. Monte Carlo simulations are performed assess probability densities shape measures asphericity nature asphericity. Comparison with mean confirm our reasoning explain stiff regime, where response prevails.
