Separation of Colloidal Particles in a Packed Column using Depletion Forces
Depletion forces were used to separate an equinumber density binary dispersion of 1.5 and 0.82 µm polystyrene sulfate (PS) particles. Experiments consisted of injecting a pulse of a binary dispersion of PS particles into the inlet of a packed bed of 0.5 mm silica collector beads. Prior to …

Depletant induced attractions in red blood cells
… a disperse limit subject to short range implicit depletion forces. This work demonstrates that the depletant interaction is sufficient to account for sudden transitions into aggregate states. Furthermore, this work demonstrates that the specific volume fraction of depletants is directly linked to …

Depletion induced bundling of rod-like colloids and simulations of triple helix bundles
… simulations of rod-like colloids acting under depletion forces. In these simulations, we found bundling of the rods above a given strength of the depletion force. We then analyzed the bundle formation process and how the shape and flexibility of the rods could effect bundle formation. We then …

DNA Driven Assembly at Solid and Liquid Interfaces
… sculpted attractive interactions via depletion forces and/or magnetic fields. The highly specific and thermally reversible nature of binding between two complementary single strands of DNA allows us to encode binding rules among various (solid or liquid) components of the system. The …

Structure formation and fractionation in systems of colloidal rods
… attractive interactions like van der Waals or depletion forces cannot be neglected, however. In the first part of this work, the phase behavior of monodisperse attractive rods is characterized for different interaction strengths. Phase diagrams as a function of rod length and pressure are …

Forces and Stability in Ternary Colloidal Systems: Evidence of Synergistic Effects
Understanding and controlling the forces between colloidal particles in solution, along with the resulting stability of a dispersion of such particles, continues to be at topic of great interest. Although most laboratory studies focus on model systems in which the number of system species is kept …
