Axisymmetric PDMS (polydimethysiloxane) microchannels for in vitro haemodynami...
Lima, R.; Oliveira, M.S.N.; Ishikawa, Takuji; Kaji, H.; Tanaka, S.; Nishizawa, Matsuhiko; Yamaguchi, TakamiThe current microdevices used for biomedical research are often manufactured using microelectromechanical systems (MEMS) technology. Although it is possible to fabricate precise and reproducible rectangular microchannels using soft lithography techniques, this kind of geometry may not reflect the actual physiology of the microcirculation. Here, we present a simple method to fabricate circular PDMS microchannels...
Blood flow in microchannel with stenosis measured by a confocal micro PTV system
Fujiwara, Hiroki; Ishikawa, Takuji; Lima, R.; Imai, Yohsuke; Matsuki, Noriaki; Kaji, H.; Mori, Daisuke; Nishizawa, Matsuhiko; Yamaguchi, TakamiBlood in microcircualtion is not a homogenous fluid but the suspension of Red Blood Cells(RBC). So individual RBCs behavior is essential to get good comprehension about the blood flow in microcirculation. In this study we observe the RBCs behavior through the stenosis by using confocal-micro- PTV system. And we can observe the difference of the cell free layer thickness according to Hct.
