Multiplexed holographic molecular binding assays with internal calibration standards
Kaitlynn Snyder, Andrew D. Hollingsworth, Fook Chiong Cheong +2
Holographic molecular binding assays detect macromolecules binding to colloidal probe beads by monitoring nanometer-scale changes in the beads' diameters with holographic microscop…
Large FCC colloidal crystals under microgravity
Qian Lei, Boris Khusid, Lou Kondic +4
Here we report the results of microgravity experiments performed on the International Space Station (ISS) to study crystallized, metastable colloidal liquids in the region of the h…
Anomalous tumbling of colloidal ellipsoids in Poiseuille flows
Lauren E. Altman, Andrew D. Hollingsworth, David G. Grier
Shear flows cause aspherical colloidal particles to tumble so that their orientations trace out complex trajectories known as Jeffery orbits. The Jeffery orbit of a prolate ellipso…
Holographic immunoassays
Kaitlynn Snyder, Rushna Quddus, Andrew D. Hollingsworth +2
The size of a probe bead reported by holographic particle characterization depends on the proportion of the surface area covered by bound target molecules and so can be used as an…
Freezing on a Sphere
Rodrigo E. Guerra, Colm P. Kelleher, Andrew D. Hollingsworth +1
The best-understood crystal ordering transition is that of two-dimensional freezing, which proceeds by the rapid eradication of lattice defects as the temperature is lowered below…
Charged hydrophobic colloids at an oil/aqueous phase interface
Colm P. Kelleher, Anna Wang, Guillermo Iván Guerrero-García +6
Hydrophobic PMMA colloidal particles, when dispersed in oil with a relatively high dielectric constant, can become highly charged. In the presence of an interface with a conducting…
Phase behavior of charged colloids at a fluid interface
Colm P. Kelleher, Rodrigo E. Guerra, Andrew D. Hollingsworth +1
We study the phase behavior of a system of charged colloidal particles that are electrostatically bound to an almost flat interface between two fluids. We show that, despite the fa…
