Conformations of semiflexible polymers and filaments
… function and the technological applications of semiflexible polymers, such as DNA, actin filaments and carbon nanotubes, strongly depend on their rigidity. Semiflexible polymers are characterized by their persistence length, the definition of which is the subject of the first part of this …

Force-response statistics of semiflexible polymers
… to probe the physical properties of these biopolymers in unprecedented detail. These methods have led to a greater understanding of a wide range of biologically relevant processes, including the dynamics of cytoskeletal filaments, the stability of DNA double helix, and the formation of …

Dynamics of single semiflexible filaments in a viscous fluid
Numerous cellular functions rely on semiflexible filaments as structural elements (F-actin, microtubules), locomotive organs (flagella, cilia) or carriers of information (DNA). Flexible and semiflexible polymers are also commonly encountered in technological applications, specifically in chemical …

Interplay of flow and microstructure in complex fluids: Semiflexible polymer solutions and emulsions
… presented for Brownian dynamics simulations of semiflexible bead-rod chains with configuration-dependent anisotropic bead friction tensor. The algorithm for the dynamics and the stress generalizes an earlier one restricted to isotropic, configuration-independent friction (Grassia and Hinch …

Computational studies of semiflexible polymer translocation in nanopore systems
… flexible, and the translocation dynamics of semiflexible molecules are not very well understood. In this thesis, in a set of articles, several aspects of translocation with semiflexible polymers in various nanopore systems are explored using molecular dynamics simulations. We look at the …

Studying self-entangled DNA at the single molecule level
… the prevalence of knots in important biological polymers, to date, the physics of knots is only partially understood. DNA has become a well-accepted model system for investigating the physics of single polymer molecules due to its tremendous biological significance and useful experimental …

Mechanics of biopolymer networks, stimuli responsive particle suspensions, and their combinations
… stiffens under the stress owing to its semiflexible nature. This helps achieve a higher sensitivity to the external field in the fabricated composites compared to the traditional flexible-polymer matrix of composite systems. Phenomenological models are developed that quantify this …

Sequence Dependent Elasticity of DNA
The DNA contained in every living cell not only stores the genetic information; it functions in a complex molecular network that can condense, transcribe, replicate and repair genes. The essential role played by the sequence dependent structure and deformability of DNA in these basic processes of …

Atomic force microscopy methods to study protein phase transitions
… is very well-modelled by theory of semi-flexible polymers, which quantitatively predicts the range in which loop structures exist. These findings suggest that the formation of amyloid loops is a generic process, governed by the fact that intermediate protofibrillar species behave as semiflexible …
