  • Shear-induced platelet margination in a microchannel PHYSICAL REVIEW E Zhao, H., Shaqfeh, E. S. 2011; 83 (6)

    Abstract

    The lateral migration of platelets in a microchannel is studied numerically where the hydrodynamic interactions between red cells, platelets, and vessel walls are resolved by the Stokes flow boundary integral equations. The simulations provide a clear physical description of the expulsion of the platelets by the velocity fluctuations in the core cellular flow toward the cell-depleted layer near the wall. The lateral migration is shown to be diffusional, and we further demonstrate, in agreement with previous experiments, that the diffusivity scales sublinearly with the shear rate if the relevant capillary number, Ca<1, as a result of its intrinsic dependence on the deformation of red cells.

    Abstract

    DNA has been recently explored as a powerful tool for developing molecular scaffolds for making reproducible and reliable metal contacts to single organic semiconducting molecules. A critical step in the process of exploiting DNA-organic molecule-DNA (DOD) array structures is the controlled tethering and stretching of DNA molecules. Here we report the development of reproducible surface chemistry for tethering DNA molecules at tunable density and demonstrate shear flow processing as a rationally controlled approach for stretching/aligning DNA molecules of various lengths. Through enzymatic cleavage of ?-phage DNA to yield a series of DNA chains of various lengths from 17.3 ?m down to 4.2 ?m, we have investigated the flow/extension behavior of these tethered DNA molecules under different flow strengths in the flow-gradient plane. We compared Brownian dynamic simulations for the flow dynamics of tethered ?-DNA in shear, and found our flow-gradient plane experimental results matched well with our bead-spring simulations. The shear flow processing demonstrated in our studies represents a controllable approach for tethering and stretching DNA molecules of various lengths. Together with further metallization of DNA chains within DOD structures, this bottom-up approach can potentially enable efficient and reliable fabrication of large-scale nanoelectronic devices based on single organic molecules, therefore opening opportunities in both fundamental understanding of charge transport at the single molecular level and many exciting applications for ever-shrinking molecular circuits.

  • The conformational dynamics of lambda-DNA in the anti-Brownian electrokinetic trap: Brownian dynamics and Monte Carlo simulation JOURNAL OF CHEMICAL PHYSICS Dambal, A., Shaqfeh, E. S. 2009; 131 (22)

    Abstract

    In this work, we examine the conformational dynamics of long polymer molecules under confinement, as in the recently developed anti-Brownian electrokinetic (ABEL) trap [A. Cohen and W. Moerner, Proc. Natl. Acad. Sci. USA. 103, 4362 (2006)]. We analyze polymer motion using Brownian dynamics simulations (bead-spring and bead-rod models) and via Monte Carlo methods. We first verify Cohen and Moerner's (2007) single molecule observations regarding the existence of short time correlations [Phys. Rev. Lett. 98, 116001 (2007)] in the motion of a polymer's center of mass, which arise due to fluctuating hydrodynamic interactions. Thereafter, following Cohen and Moerner, we use principal component analysis to extract the principal modes governing polymer conformation and find that confinement and backbone bending only affect small polymers and should not play a significant role in the dynamics of long polymers such as lambda-DNA. We find excellent agreement between our principal component analysis modes and those measured by Cohen and Moerner [Proc. Natl. Acad. Sci. U.S.A. 104, 12622 (2007)]. Finally, to explore the effect of excluded volume, in particular, the effect of the excluded volume parameter (z), we use image-image correlations to examine its relation to polymer dynamics. Image-image correlation measurements performed on lambda-DNA in the ABEL trap did not display a simple exponential-type behavior and motivated the use of stretched exponential functions to determine the characteristic timescale (tau) governing conformational dynamics. We show that tau scales with polymer length as N(2) and decreases with increasing z. Furthermore, we can collapse a variety of data when tauN(-2) is plotted with respect to N/z(m) (m=0.14 for freespace and 0.366 for walls).

    Abstract

    We present a theoretical and experimental study of the role of hydrodynamic interactions on the motion and dispersion of metal rodlike particles in the presence of an externally applied electric field. In these systems, the electric field polarizes the particles and induces an electroosmotic flow relative to the surface of each particle. The simulations include the effect of the gravitational body force, buoyancy, far-field hydrodynamic interactions, and near-field lubrication forces. The particles in the simulations and experiments were observed to experience repeated pairing interactions in which they come together axially with their ends approaching each other, slide past one another until their centers approach, and then push apart. These interactions were confirmed in measurements of particle orientations and velocities, pair distribution functions, and net dispersion of the suspension. For large electric fields, the pair distribution functions show accumulation and depletion regions consistent with many pairing events. For particle concentrations of 10;{8}particles/mL and higher, dispersion within the suspension dramatically increases with increased field strength.

  • Brownian demixing and wall effects in sedimenting suspensions of orientable particles PHYSICAL REVIEW E Hoffman, B. D., Shaqfeh, E. S. 2008; 78 (5)

    Abstract

    We describe the Brownian demixing of sedimenting suspensions, a recently discovered phenomenon in which increases in the thermal energy can destabilize a system of orientable particles subjected to a torque to fluctuations in concentration. Through use of Brownian dynamics simulation and a mean-field analysis, we demonstrate that demixing occurs in a model system composed of slender rigid rods sedimenting between no-slip walls. Additionally, we describe the effects of wall separation distance on suspension stability.

  • Dynamics of DNA tumbling in shear to rotational mixed flows: Pathways and periods PHYSICAL REVIEW E Lee, J. S., Shaqfeh, E. S., Muller, S. J. 2007; 75 (4)

    Abstract

    The tumbling dynamics of DNA have been examined via experiments and Brownian dynamics (BD) simulations in mixed flows that vary from pure shear to pure rotation. In shear, tumbling pathways and periods agree well with earlier studies; in rotation-dominated flows, a new tumbling pathway is identified and experimentally observed. Based on these results, we have developed robust scaling laws for DNA tumbling in both shear and rotational flows and have found a critical flow-type parameter for transition from the shearlike flow regime to the rotation-dominated one.

  • Ergodicity breaking and conformational hysteresis in the dynamics of a polymer tethered at a surface stagnation point JOURNAL OF CHEMICAL PHYSICS Beck, V. A., Shaqfeh, E. S. 2006; 124 (9)

    Abstract

    We study the dynamics of long chain polymer molecules tethered to a plane wall and subjected to a stagnation point flow. Using a combination of theory and numerical techniques, including Brownian dynamics (BD), we demonstrate that a chain conformation hysteresis exists even for freely draining (FD) chains. Hydrodynamic interactions (HI) between the polymer and the wall are included in the BD simulations. We find qualitative agreement between the FD and HI simulations, with both exhibiting simultaneous coiled and stretched states for a wide range of fixed flow strengths. The range of state coexistence is understood by considering an equivalent projected equilibrium problem of a two state reaction. Using this formalism, we construct Kramers rate theory (from the inverse mean first passage time for a Markov process) for the hopping transition from coil to stretch and stretch to coil. The activation energy for this rate is found to scale proportionally to chain length or Kuhn step number. Thus, in the limit of infinite chain size the hopping rates at a fixed value of the suitably defined Deborah number approach zero and the states are "frozen." We present the results that demonstrate this "ergodicity breaking."

  • Characteristic periodic motion of polymers in shear flow PHYSICAL REVIEW LETTERS Schroeder, C. M., Teixeira, R. E., Shaqfeh, E. S., Chu, S. 2005; 95 (1)

    Abstract

    The motion of both free and tethered polymer molecules as well as rigid Brownian rods in unbound shear flow is found to be characterized by a clear periodicity or tumbling frequency. Periodicity is shown using a combination of single molecule DNA experiments and computer simulations. In all cases, we develop scaling laws for this behavior and demonstrate that the frequency of characteristic periodic motion scales sublinearly with flow rate.

    Abstract

    Using methods adapted from the simulation of suspension dynamics, we have developed a Brownian dynamics algorithm with multibody hydrodynamic interactions for simulating the dynamics of polymer molecules. The polymer molecule is modeled as a chain composed of a series of inextensible, rigid rods with constraints at each joint to ensure continuity of the chain. The linear and rotational velocities of each segment of the polymer chain are described by the slender-body theory of Batchelor [J. Fluid Mech. 44, 419 (1970)]. To include hydrodynamic interactions between the segments of the chain, the line distribution of forces on each segment is approximated by making a Legendre polynomial expansion of the disturbance velocity on the segment, where the first two terms of the expansion are retained in the calculation. Thus, the resulting linear force distribution is specified by a center of mass force, couple, and stresslet on each segment. This method for calculating the hydrodynamic interactions has been successfully used to simulate the dynamics of noncolloidal suspensions of rigid fibers [O. G. Harlen, R. R. Sundararajakumar, and D. L. Koch, J. Fluid Mech. 388, 355 (1999); J. E. Butler and E. S. G. Shaqfeh, J. Fluid Mech. 468, 204 (2002)]. The longest relaxation time and center of mass diffusivity are among the quantities calculated with the simulation technique. Comparisons are made for different levels of approximation of the hydrodynamic interactions, including multibody interactions, two-body interactions, and the "freely draining" case with no interactions. For the short polymer chains studied in this paper, the results indicate a difference in the apparent scaling of diffusivity with polymer length for the multibody versus two-body level of approximation for the hydrodynamic interactions.

    Abstract

    Highly extensible Escherichia coli DNA molecules in planar extensional flow were visualized in dilute solution by fluorescence microscopy. For a narrow range of flow strengths, the molecules were found in either a coiled or highly extended conformation, depending on the deformation history of the polymer. This conformation hysteresis persists for many polymer relaxation times and is due to conformation-dependent hydrodynamic forces. Polymer conformational free-energy landscapes were calculated from computer simulations and show two free-energy minima for flow strengths near the coil-stretch transition. Hysteresis cycles may directly influence bulk-solution stresses and the development of stress-strain relations for dilute polymer flows.

    Abstract

    We examine the dynamics of DNA molecules in mixed flows where the ratio of vorticity to strain rate may be slightly above or below unity via Brownian dynamics simulation. We find that the chain dynamics in these flows are dramatically different than those found for simple shear flow. When the strain rate exceeds vorticity, the dynamics are found to be driven by the extra amount of straining. For vorticity-dominated flows, a periodicity in chain extension is observed with considerable chain deformation.

    Abstract

    The microscopic and macroscopic response of a polymer solution in start-up shear flow was investigated using fluorescence microscopy of single molecules, bulk viscosity measurements, and Brownian dynamics simulations. An overshoot in viscosity was observed upon flow inception and understood via the observed molecular extension and by simulation findings. Increasing the polymer concentration up to six times the overlap concentration ( C(*)) has no effect on the character of the dynamics of individual molecules.
