The Laboratory of Fields, Flows, and Interfaces (LoFFI) at Ryerson University
Sorting of cells and biological materials is typically done using a fluorescence detection system that has a large footprint. However, cells can also be sorted by their attachment to antibody-coated magnetic beads in magnetic separation systems. At the LoFFI, they are developing a microfluidic system that uses a magnetic field to sort magnetic beads by deflecting them in the direction normal to the flow. The system can be applied to sort cells and biological materials by binding them to beads of different sizes and magnetic susceptibilities, and flowing them through the microfluidic device.
