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…
Multi-angle holographic characterization of individual fractal aggregates
Rafe Abdulali, Lauren E. Altman, David G. Grier
Holographic particle characterization uses quantitative analysis of holographic microscopy data to precisely and rapidly measure the diameter and refractive index of individual col…
Holographic characterization and tracking of colloidal dimers in the effective-sphere approximation
Lauren E. Altman, Rushna Quddus, Fook Chiong Cheong +1
An in-line hologram of a colloidal sphere can be analyzed with the Lorenz-Mie theory of light scattering to measure the sphere's three-dimensional position with nanometer-scale pre…
Interpreting Holographic Molecular Binding Assays with Effective Medium Theory
Lauren E. Altman, David G. Grier
Holographic molecular binding assays use holographic video microscopy to directly detect molecules binding to the surfaces of micrometer-scale colloidal beads by monitoring associa…
CATCH: Characterizing and Tracking Colloids Holographically using deep neural networks
Lauren E. Altman, David G. Grier
In-line holographic microscopy provides an unparalleled wealth of information about the properties of colloidal dispersions. Analyzing one colloidal particle's hologram with the Lo…
