Abstract(s)
In microcirculation the flow behavior of red blood cells
(RBCs) plays a crucial role in many physiological and
pathological phenomena. For instance, the interaction of RBCs
in shear flow is believed to play an important role to the
thrombogenesis process. Despite the relevance of this
phenomenon on the blood mass transport, very little studies
have been performed during the years, partly due to the
absence of adequate visualization techniques able to obtain
both direct and quantitative measurements on multi-RBCs
motions in concentrated suspensions. Past studies on both
individual and concentrated RBCs used conventional
microscopes and/or ghost cells to obtain visible trace RBCs at
high concentration suspension of blood cells [1, 2]. Recently,
advances of confocal microscopy and consequent advantages
over conventional microscopes have led to an emerging
technique known as confocal micro-PIV [3, 4].
This paper presents the application of a confocal micro-
PTV system to measure RBC-RBC hydrodynamic interactions
in flowing blood.
