Intra-Droplet Magnetic Bead Separation for More Flexibility in Operation Protocols

New research in microfluidics shows a wide range of possible applications for lab-on-chip assays such as PCR and for proteomics.

Professor Richard Fair of the Digital Microfluidics Laboratory at Duke University has shown the feasibility of intra-droplet magnetic bead separation.

This method consists of performing separation in droplets with a complex mixture of multiple beads, each having different magnetic contents. It demonstrates an integrated device combining both EWD droplet actuation and intra-droplet magnetic bead manipulation. Their separation function can be operated independently, which provides flexibility when designing operation protocols in many disciplines, encompassing biology, chemistry and chemical engineering.
