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…
Motion Induced by Light: Photokinetic Effects in the Rayleigh Limit
David B. Ruffner, Aaron Yevick, David G. Grier
Structured beams of light can move small objects in surprising ways. Particularly striking examples include observations of polarization-dependent forces acting on optically isotro…
Optical forces and torques in non-uniform beams of light
David B. Ruffner, David G. Grier
The spin angular momentum in an elliptically polarized beam of light plays several noteworthy roles in optical traps. It contributes to the linear momentum density in a non-uniform…
Measuring every particle's size from three-dimensional imaging experiments
Rei Kurita, Eric R. Weeks
Often experimentalists study colloidal suspensions that are nominally monodisperse. In reality these samples have a polydispersity of 4-10%. At the level of an individual particle,…
Effects of He Impurity on Solid He Studied by Compound Torsional Oscillator
P. Gumann, M. C. Keiderling, D. Ruffner +1
Frequency shifts and dissipations of a compound torsional oscillator induced by solid He samples containing He impurity concentrations ( = 0.3, 3, 6, 12 and 25 in unit…
