Effect of transfusion materials on rouleaux formation and sedimentation rate of erythrocytes.

A microfluidic erythrocyte sedimentation rate analyzer using rouleaux formation kinetics

Red blood cells form face-to-face linear or branched structures, called as rouleaux, under static conditions or low shear rates in the presence of appropriate macromolecules (Baskurt et al. 2011a; Chien 1975; Merrill 1969; Neu and Meiselman 2007). This process is reversible, and cells can be dispersed individually when a disaggregating shear rate is applied to the cells (Baskurt et al. 2011b; L...

Analytical ultracentrifugation: sedimentation velocity and sedimentation equilibrium.

Analytical ultracentrifugation (AUC) is a versatile and powerful method for the quantitative analysis of macromolecules in solution. AUC has broad applications for the study of biomacromolecules in a wide range of solvents and over a wide range of solute concentrations. Three optical systems are available for the analytical ultracentrifuge (absorbance, interference, and fluorescence) that permi...

Sedimentation dynamics of spherical particles in confined geometries.

We study the steady-state dynamics of sedimenting non-Brownian particles in confined geometries with full hydrodynamic interactions at small but finite Reynolds numbers. We employ extensive computer simulations using a method where a continuum liquid phase is coupled through Stokesian friction to a discrete particle phase. In particular, we consider a sedimentation box which is otherwise period...
