Magnetic separation is one of the effective ways to separate specific biological entities such as DNA/RNA, bacteria, and cells from their native environment for subsequent downstream analysis. The process involves the labeling of the desired biological entity with magnetic beads followed by separating the tagged entities via a magnetic separation device. In conventional tube-based magnetic separation, magnetically labeled biological entities are retained on the inner wall of the tube by applying an external magnet, while the supernatant is decanted off. Removing the tube from the magnetic field enables resuspension of the target entity. Although widely used, there are limitations to the conventional magnetic separation method. For example, there is a significant sample loss due to multiple sample handling, washing, and transfer. In addition, manual magnetic separation systems are labor intensive and their effectiveness is user-dependent.
