Unexpected swelling of stiff DNA in a polydisperse crowded environment
Hongsuk Kang, Ngo Minh Toan, Changbong Hyeon +1
We investigate the conformations of DNA-like stiff chains, characterized by contour length () and persistence length (), in a variety of crowded environments containing mon…
Polyelectrolyte and polyampholyte effects in synthetic and biological macromolecules
Ngo Minh Toan, Bae-Yeun Ha, D. Thirumalai
The nature of electrostatic interactions involving polyanions modulate the properties of both synthetic and biological macromolecules. Although intensely studied for decades the in…
Kinetics of Loop Formation in Polymer Chains
Ngo Minh Toan, Greg Morrison, Changbong Hyeon +1
We investigate the kinetics of loop formation in flexible ideal polymer chains (Rouse model), and polymers in good and poor solvents. We show for the Rouse model, using a modificat…
Stretching Homopolymers
Greg Morrison, Changbong Hyeon, N. M. Toan +2
Force induced stretching of polymers is important in a variety of contexts. We have used theory and simulations to describe the response of homopolymers, with monomers, to forc…
Depletion effects and loop formation in self-avoiding polymers
N. M. Toan, D. Marenduzzo, P. R. Cook +1
Langevin dynamics is employed to study the looping kinetics of self-avoiding polymers both in ideal and crowded solutions. A rich kinetics results from the competition of two crowd…
Inferring the effective thickness of polyelectrolytes from stretching measurements at various ionic strengths: applications to DNA and RNA
Ngo Minh Toan, Cristian Micheletti
By resorting to the thick-chain model we discuss how the stretching response of a polymer is influenced by the self-avoidance entailed by its finite thickness. The characterization…
