Resumo(s)
Detailed knowledge on the motions and interactions of individual blood cells flowing
in microchannels is essential to provide a better understanding on the blood rheological
properties and disorders in microvessels. This paper presents the ability of a confocal
micro-PTV system to track red blood cells (RBCs) through a 100 μm circular glass
microchannel. The technique consists of a spinning disk confocal microscope, high speed
camera and a diode-pumped solid state (DPSS) laser combined with a single particle
tracking (SPT) software (MtrackJ). Detailed measurements on the motions of RBCs
were measured at different haematocrits (Hct). Our results show clearly that this
technique can provide detailed information about microscale disturbance effects caused
by the blood cells.
