The spontaneous knotting of linear chains has been well studied, but little attention has been given to the self-entanglement of chains with more complex topologies. In this work, we perform experiments with granular chains that undergo tumbling moti

Conformational phase transitions of macromolecules are an important class of problems in fundamental polymer physics. While the conformational phase transitions of linear DNA have been extensively studied, this feature of topologically complex DNA re

A kinetoplast is a planar network of catenated DNA rings with topology that resembles that of chain mail armor. In this work, we use single-molecule experiments to probe the conformation of kinetoplasts confined to slits. We find that the in-plane si

In this work, we study the ionic effects on the equilibrium size and shape of kinetoplasts, a two-dimensional (2D) network of catenated DNA rings. With increasing ionic strength from 5 to 200 mM, we observe a decrease in kinetoplast size, primarily d

We use Brownian dynamics simulations to study the topological simplification of knots that untie from chains in elongational flows. Focusing on the 81 knot, we track changes in conformational state...

As an intriguing phenomenon, knotting in DNA, proteins, and other molecules has been extensively investigated in recent years, not only because of fundamental interest in knotting but also because of significant effects of knotting on mechanical, rhe
