A passive portable microfluidic blood-plasma separator for simultaneous determination of direct and indirect ABO/Rh blood typing
(2019-09-03)
Article
Open AccessThe blood typing test is mandatory in any transfusion, organ transplant, and pregnancy situation. There is a lack of point-of-care (POC) blood typing that could perform both direct and indirect methods using a single droplet ... -
Hemostasis-on-a-chip: Impedance spectroscopy meets microfluidics for hemostasis evaluation
(2019-08-14)
Article
Open AccessIn the case of vascular injury, a complex process (of clotting) starts, involving mainly platelets and coagulation factors. This process in healthy humans is known as hemostasis, but when it is deregulated (thrombosis), ... -
