Densely packed semiflexible macromolecules in a rigid spherical capsule
(American Chemical Society, 2018-02-27)
The ordering of semiflexible polymers with persistence length lp and contour length L confined in a sphere of radius R is studied by molecular dynamics simulations of a coarse-grained model. Monomer densities are chosen ...
A cooperative transition from the semi-flexible to the flexible regime of polymer elasticity: Mitoxantrone-induced DNA condensation
(Biochimica et Biophysica Acta (BBA) - General Subjects, 2018)
Semiflexible polymers in spherical confinement: bipolar orientational order versus tennis ball states
(American Physical Society, 2017-05)
Densely packed semiflexible polymers with contour length L confined in spheres with radius R of the same order as L cannot exhibit uniform nematic order. Depending on the chain stiffness (which we vary over a wide range), ...
Grand-canonical solution of semi-flexible self-avoiding trails on the bethe lattice

Droplet transport in a nanochannel coated by hydrophobic semiflexible polymer brushes: the effect of chain stiffness
(American Chemical Society, 2017-09)
We study the influence of chain stiffness on droplet flow in a nano-channel, coated with semiflexible hydrophobic polymers by means of non-equilibrium molecular-dynamics simulations. The studied system is then a moving ...
Brushes of semiflexible polymers in equilibrium and under flow in a super-hydrophobic regime
(Royal Society of Chemistry, 2015-06)
We performed molecular dynamics simulations to study the equilibrium and flow properties of a liquid ina nano-channel with confining surfaces coated with a layer of grafted semiflexible polymers. Thecoverage spans a wide ...
Pressure responsive gating in nanochannels coated by semiflexible polymer brushes
(Royal Society of Chemistry, 2019-06)
We study by coarse-grained molecular-dynamics simulations the liquid flow in a slit channel with the inner walls coated by semiflexible polymer brushes. The distance between walls is close enough such that polymers grafted ...
Power-law creep behavior of a semiflexible chain
(AMER PHYSICAL SOC, 2008)
Rheological properties of adherent cells are essential for their physiological functions, and microrheological measurements on living cells have shown that their viscoelastic responses follow a weak power law over a wide ...
Packing structure of semiflexible rings
(National Academy of Sciences, 2020-02-18)
Unraveling the packing structure of dense assemblies of semiflexible rings is not only fundamental for the dynamical description of polymer rings, but also key to understand biopackaging, such as observed in circular DNA ...
