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…
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…
Quantitative differentiation of protein aggregates from other subvisible particles in viscous mixtures through holographic characterization
Annemarie Winters, Fook Chiong Cheong, Mary Ann Odete +5
We demonstrate the use of holographic video microscopy to detect individual subvisible particles dispersed in biopharmaceutical formulations and to differentiate them based on mate…
Optical forces arising from phase gradients
Yohai Roichman, Bo Sun, Yael Roichman +2
We demonstrate both theoretically and experimentally that gradients in the phase of a light field exert forces on illuminated objects, including forces transverse to the direction…
