Within the last decade, fluorescence microscopy of single molecules of DNA in a plethora of
flow fields has allowed an unprecedented examination of the dynamics of polymers in flow …

Entangling and twisting of cellular DNA (ie, supercoiling) are problems inherent to the
helical structure of double-stranded DNA. Supercoiling affects transcription, DNA replication …

Topological entanglement in polymers and biopolymers is a topic that involves different
fields of science such as chemistry, biology, physics, and mathematics. One of the main …

Semiflexible polymers subject to hydrodynamic forcing play an important role in cytoskeletal
motions in the cell, particularly when filaments guide molecular motors whose motions …

Based on extensive Brownian dynamics simulations we study the thermal motion of a tracer
bead in a cross-linked, flexible gel in the limit when the tracer particle size is comparable to …

We report experimental results from a de novo designed oligopeptide that intermolecularly
self-assembles into rigid hydrogel networks after an intramolecular folding event …

The dynamics of supercoiled DNA play an important role in various cellular processes such
as transcription and replication that involve DNA supercoiling. We present experiments that …

Nanomanipulation of individual RNA molecules, using laser optical tweezers, has made it
possible to infer the major features of their energy landscape. Time-dependent mechanical …

This paper is aimed to develop a Brownian dynamics simulation method for strongly
confined semiflexible polymers where numerical simulation plays an indispensable role in …

ATPases are a group of enzymes that can cyclically convert the free energy of ATP
hydrolysis into mechanical work. GTPases are another class of enzymes that are …
