Abstract
A separation and collection device for cells and biomolecules includes an annular tube and several magnetic beads configured to identify and bind with different cells or molecules in the biological sample. The annular tube defines a through hole for the biological sample to exit. Sizes of different groups of magnetic beads are different. An aperture size of a through hole is changeable such that the plurality of groups of magnetic beads can flow through the through hole in a certain order. A testing system including the separation and collection device is further disclosed.
