In this review, we provide an organized summary of the theoretical and computational
results that are available for polymers subject to spatial or topological constraints. Because …

It has been more than 50 years since the elucidation of the structure of double-helical DNA.
Despite active research and progress in DNA biology and biochemistry, much remains to be …

Biological semiflexible polymers and filaments such as collagen, fibronectin, actin,
microtubules, coiled-coil proteins, DNA, siRNA, amyloid fibrils, etc., are ubiquitous in nature …

The aggregation of proteins is central to many aspects of daily life, including food
processing, blood coagulation, eye cataract formation disease and prion-related …

Chromosome inheritance depends on centromeres, epigenetically specified regions of
chromosomes. While conventional human centromeres are known to be built of long tandem …

Protein fibrils resulting from assembly of proteins or peptides into long, insoluble, highly
ordered fibrillar structures are emerging as one of the fastest growing scientific areas, since …

Kinetoplast DNA (kDNA) is a two-dimensional Olympic-ring-like network of mutually linked
DNA minicircles found in certain parasites called trypanosomes. Understanding the self …

We have characterized the polymer physics of single-stranded DNA (ssDNA) using atomic
force microscopy. The persistence length ℓ p of circular ssDNA adsorbed on a modified …

We report on a numerical study of the equilibrium metric scaling features and knotting
properties of linear and circular model DNA chains inside cylindrical channels. The model …

Advanced Monte Carlo simulations are used to study the effect of nanoslit confinement on
metric and topological properties of model DNA chains. We consider both linear and …
