Centrifugal microfluidic disk and processing method using the same

摘要

This invention provides a centrifugal microfluidic disk and methods for separating targets or cells and collecting the targets or cells in the centrifugal microfluidic disk by using the density gradient.

主权项

1. A centrifugal microfluidic disk, at least comprising:
a sample inlet, located at a first level for loading a blood or biological sample; a separation chamber, connected to the sample inlet, wherein the separation chamber contains an arc-shape portion and a density gradient solution is loaded into the separation chamber; a chemical inlet, located at a second level for loading a chemical; a collection chamber, connected to the separation chamber; a conveying channel, connected to the collection chamber; and a junction extending vertically from the first level to the second level and connecting the conveying channel located at the second level and the separation chamber located at the first level, wherein the chemical inlet and the sample inlet are located at different levels.
