Hot Brownian motion and photophoretic self-propulsionSchachoff, Romy, Selmke, Markus, Bregulla, Andreas, Cichos, Frank, Rings, Daniel, Chakraborty, Dipanjan, Kroy, Klaus, Günther, Katrin, Henning-Knechtel, Anja, Sperling, Evgeni, Mertig, Michael 03 March 2016 (has links) (PDF)
We describe the motion of heated particles in a simple liquid, for which we can theoretically derive generalized fluctuation-dissipation relations that hold far from equilibrium, as we demonstrate both experimentally and via molecular-dynamics simulations. Due to persistent laser-light absorption, these particles excite a radially symmetric or asymmetric (Janus particles) temperature profile in the solvent, which affects their random (Brownian) and systematic (self-phoretic) motion. In case of a radially symmetric temperature profile, we show that the particles perform “hot Brownian motion” (HBM), with different effective temperatures pertaining to their various degrees of freedom. We moreover predict and experimentally observe a peculiar dependence of their diffusivity on the particle size. In case of an asymmetric temperature profile, we find a superimposed self-phoretic directed motion. To adjust the importance of this “active” motion relative to the random hot Brownian motion, the shape of the particle is modified by binding DNA molecules and DNA origami to Janus beads. The persistence of the directed transport can thereby greatly be enhanced.

DNA under confinement and the use of DNA as confinementBrutzer, Hergen, Sperling, Evgeni, Günther, Katrin, Dikic, Jasmina, Schwarz, Friedrich, Klaue, Daniel, Cichos, Frank, Mertig, Michael, Seidel, Ralf 03 March 2016 (has links) (PDF)
In living systems DNA is subjected to considerable confinement but the molecule acts itself also as a confinement mechanism for cellular structures. Here we present investigations that study DNA under the confinement of supercoiling and within nanofluidic channels. Furthermore, we use DNA to confine the motion of microscopic and nanoscopic objects. In particular, we show how the motion dynamics of DNA-attached magnetic particles under external tension is affected and how DNA can confine the diffusion of enzymes to one dimension to follow the DNA contour.
