Spira Mirabilis enhanced density gradient centrifguation
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.
