Chirality for crooked curves
Giovanni Dietler, Robert Kusner, Wöden Kusner +2
Chiral objects rotate when placed in a collimated flow or wind. We exploit this hydrodynamic intuition to construct a tensorial chirality measure for rigid filaments and curves. Th…
Periodic motion of sedimenting flexible knots
Magdalena Gruziel, Krishnan Thyagarajan, Giovanni Dietler +3
We study the dynamics of knotted deformable closed chains sedimenting in a viscous fluid. We show experimentally that trefoil and other torus knots often attain a remarkably regula…
Nanoscale spatially resolved infrared spectra from single microdroplets
Thomas Müller, Francesco Simone Ruggeri, Andrzej J. Kulik +4
Droplet microfluidics has emerged as a powerful platform allowing a large number of individual reactions to be carried out in spatially distinct microcompartments. Due to their sma…
Excluded volume effects on semiflexible ring polymers
Fabian Drube, Karen Alim, Guillaume Witz +2
Two-dimensional semiflexible polymer rings are studied both by imaging circular DNA adsorbed on a mica surface and by Monte Carlo simulations of phantom polymers as well as of poly…
Conformation of Circular DNA in 2 Dimensions
G. Witz, K. Rechendorff, J. Adamcik +1
The conformation of circular DNA molecules of various lengths adsorbed in a 2D conformation on a mica surface is studied. The results confirm the conjecture that the critical expon…
Force spectroscopy on DNA by FM-AFM
Giovanni Di Santo, Susana Tobenas, Jozef Adamcik +1
We present imaging and force spectroscopy measurements of DNA molecules adsorbed on functionalized mica. By means of Non-Contact mode AFM (NC-AFM) in Ultra High Vacuum (UHV), the f…
