Botanical Ratchets
I. M. Kulić, M. Mani, H. Mohrbach +2
Ratcheting surfaces are a common motif in nature and appear in plant awns and grasses. They are known to profer selective advantages for seed dispersion and burial. In two simple m…
Motor driven microtubule shape fluctuations - force from within the lattice
Herve Mohrbach, Igor M. Kulic
We develop a general theory of microtubule (MT) deformations by molecular motors generating internal force doublets within the MT lattice. We describe two basic internal excitation…
Apparent Persistence Length Renormalization of Bent DNA
Igor M. Kulic, H. Mohrbach, V. Lobaskin +2
We derive the single molecule equation of state (force-extension relation) for DNA molecules bearing sliding loops and deflection defects. Analytical results are obtained in the la…
Twirling DNA Rings - Swimming Nanomotors Ready for a Kickstart
Igor M. Kulic, Rochish Thaokar, Helmut Schiessel
We propose a rotary DNA nanomachine that shows a continuous rotation with a frequency of 10^2 -10^4 Hz. This motor consists of a DNA ring whose elastic features are tuned such that…
Twist-bend instability for toroidal DNA condensates
Igor M. Kulic, Denis Andrienko, Markus Deserno
We propose that semiflexible polymers in poor solvent collapse in two stages. The first stage is the well known formation of a dense toroidal aggregate. However, if the solvent is…
DNA Spools under Tension
I. M. Kulic, H. Schiessel
DNA-spools, structures in which DNA is wrapped and helically coiled onto itself or onto a protein core are ubiquitous in nature. We develop a general theory describing the non-equi…
