Abstract

The centrifugal microfluidic “lab-on-a-disc” paradigm is particularly suited to the pre-conditioning of whole blood. In this work we define the geometry of sedimentation chambers using the Spira Mirabilis (equiangular spiral) and so enhance the Boycott Effect and increase the speed at which blood may be stratified using a density gradient media. We find that using the Spira Mirabilis defined chambers can increase the speed of stratification by up to 25% compared with equivalent linear chambers.

螺旋藻增强密度梯度离心

离心微流体“盘上实验室”模式特别适合全血预处理。在这项工作中，我们使用Spira Mirabilis(等角螺旋)定义了沉降室的几何形状，从而增强了Boycott效应，并提高了使用密度梯度介质分层血液的速度。我们发现，与等效线性室相比，使用Mirabilis Spira定义的室可以将分层速度提高25%。
