Intra-droplet magnetic bead manipulation integrated on a digital microfluidic chip

This paper demonstrates a device which is capable of performing both magnetic molecular segregation within a droplet as well as droplet actuation. Segregation of magnetic beads is performed within a droplet while the droplet is dispensed and transported using electrowetting on dielectric (EWD). The reason it is important to investigate such devices is that the capability could be used in current applications, including immunoassays, cell labeling and DNA isolation.
