Nanoconfined Circular and Linear DNA: Equilibrium Conformations and Unfolding Kinetics

Nanoconfined Circular and Linear DNA: Equilibrium Conformations and Unfolding Kinetics

Studies of circular DNA confined to nanofluidic channels are relevant both from a fundamental polymer-physics perspective and due to the importance of circular DNA molecules in vivo. We here observe the unfolding of confined DNA from the circular to linear configuration as a light-induced double-strand break occurs, characterize the dynamics, …
