The field of microrheology is concerned with how materials store and dissipate mechanical
energy as a function of length scale. Recent developments in the theory and instrumentation …

Linear rheological properties of tightly-entangled isotropic solutions of semi-flexible
polymers are calculated using a tube model, and qualitative predictions are given for the …

We have investigated the viscosity and the plateau modulus of actin solutions with a
magnetically driven rotating disk rheometer. For entangled solutions we observed a scaling …

Solutions and gels of the filamentous protein F-actin have not only been the subject of
numerous recent biophysical studies, but have also proven to be quite fruitful model systems …

We present a data analysis procedure that provides the solution to a long-standing issue in
microrheology studies, ie the evaluation of the fluids' linear viscoelastic properties from the …

We have studied the sol-gel transition, the viscoelastic and the structural properties of
networks constituted of semiflexible actin filaments cross-linked by α-actinin. Cross-linking …

The dynamic structure factor for molecular chains with variable stiffness in a dilute solution is
investigated. In the limit of small scattering vectors q only the overall translational motion of …

The intramolecular dynamics of flexible and semiflexible polymers in response to active
noise is studied theoretically. The active noise may either originate from interactions of a …

We have investigated the thermodynamic and dynamic behavior of multistranded β-
lactoglobulin protein fibrils in water, by combining static, dynamic, and depolarized dynamic …

We present a theory for the elasticity of cross-linked stiff polymer networks. Stiff polymers,
unlike their flexible counterparts, are highly anisotropic elastic objects. Similar to mechanical …
