How confinement or a physical constraint modifies polymer chains is not only a classical
problem in polymer physics but also relevant in a variety of contexts such as single-molecule …

In recent years polymer translocation, ie, transport of polymeric molecules through
nanometer-sized pores and channels embedded in membranes, has witnessed strong …

Flexible polymers such as long DNA, RNA molecules, and proteins, can pass through a
narrow pore whose size is comparable to their molecular thickness. We highlight the …

DNA confinement in nanochannels is emerging as an important tool for genomics and an
excellent platform for testing the theories of confined wormlike polymers. Using cutting-edge …

During early embryogenesis of the nematode, Caenorhabditis elegans, the chromatin
motion markedly decreases. Despite its biological implications, the underlying mechanism …

Many viruses use molecular motors that generate large forces to package DNA to near-
crystalline densities inside preformed viral proheads. Besides being a key step in viral …

We study by extensive computer simulations the looping characteristics of linear polymers
with varying persistence length inside a spherical cavity in the presence of macromolecular …

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 …

We show that arrays of nanopit structures etched in a nanoslit can control the positioning
and conformation of single DNA molecules in nanofluidic devices. By adjusting the spacing …

Crowding and confinement have often been used synonymously with regard to their effect
on the structure and dynamics of proteins. In this work, we have investigated the unfolding of …
