  1. pmc Controlling Brownian motion of single protein molecules and single fluorophores in aqueous buffer
    Adam E Cohen
    Dept of Chemistry, Stanford University, Stanford, CA 94305, USA
    Opt Express 16:6941-56. 2008
    ..The feedback latency is set by the finite rate of arrival of photons. We demonstrate trapping of individual molecules of the protein GroEL in buffer, and we show confinement of single fluorophores of the dye Cy3 in water...
  2. doi request reprint The cat that caught the canary: what to do with single-molecule trapping
    Adam E Cohen
    Harvard University, Cambridge, Massachusetts 02138, USA
    ACS Nano 5:5296-9. 2011
    ..We propose areas of investigation in which anti-Brownian electrokinetic (ABEL) trapping of single molecules is likely to lead to significant new insights into biomolecular dynamics...

    Adam E Cohen
    Department of Physics, 382 Via Pueblo Mall, Stanford University, Stanford, California 94305 4060, USA
    Phys Rev Lett 91:235506. 2003
    ..A sufficiently strong ac field causes the polymer to extend spontaneously to almost its full contour length. The theory is applied to recent experiments on dielectrophoretic stretching of DNA...
  4. pmc Principal-components analysis of shape fluctuations of single DNA molecules
    Adam E Cohen
    Department of Chemistry, Stanford University, Stanford, CA 94305, USA
    Proc Natl Acad Sci U S A 104:12622-7. 2007
    ..The modes show strong signs of nonlinear hydrodynamics, a feature of the underlying equations of polymer dynamics that has not previously been reported and is neglected in the widely used Rouse and Zimm approximations...
  5. pmc Internal mechanical response of a polymer in solution
    Adam E Cohen
    Department of Physics, Stanford University, Stanford, California 94305, USA
    Phys Rev Lett 98:116001. 2007
    ..We find a nonmonotonic radial dependence of the relaxation time. In contrast with earlier measurements on freely diffusing dsDNA, we observe clear signs of internal hydrodynamic interactions...
  6. pmc Suppressing Brownian motion of individual biomolecules in solution
    Adam E Cohen
    Department of Physics, Stanford University, 381 Via Pueblo Mall, Stanford, CA 94305, USA
    Proc Natl Acad Sci U S A 103:4362-5. 2006
    ..We also demonstrate trapping and manipulation of single virus particles, lipid vesicles, and fluorescent semiconductor nanocrystals...

    Proc Natl Acad Sci U S A 100:12141-6. 2003
    ..Our mesoscopic continuum theory is capable of quantifying observations of these structures and is suggestive of their occurrence in other filamentous assemblies as well...
