Computer-Generated Holographic Optical Tweezer Arrays
Eric R. Dufresne, Gabriel C. Spalding, Matthew T. Dearing +2
Holographic techniques significantly extend the capabilities of laser tweezing, making possible extended trapping patterns for manipulating large numbers of particles and volumes o…
Brownian Dynamics of a Sphere Between Parallel Walls
Eric R. Dufresne, David Altman, David G. Grier
We describe direct imaging measurements of a colloidal sphere's diffusion between two parallel surfaces. The dynamics of this deceptively simple hydrodynamically coupled system hav…
Hydrodynamic Coupling of Two Brownian Spheres to a Planar Surface
Eric R. Dufresne, Todd M. Squires, Michael P. Brenner +1
We describe direct imaging measurements of the collective and relative diffusion of two colloidal spheres near a flat plate. The bounding surface modifies the spheres' dynamics, ev…
