Microfluidic magnetic separator using an array of soft magnetic elements
We present the design, fabrication, characterization, and demonstration of a new passive magnetic bead separator. The device operates in an effective state when magnetized by an external magnetic field of only 50 mT , which is available from a tabletop electromagnet. We demonstrate the complete capt...

| Zusammenfassung: | We present the design, fabrication, characterization, and demonstration of a new passive magnetic bead separator. The device operates in an effective state when magnetized by an external magnetic field of only
50
mT
, which is available from a tabletop electromagnet. We demonstrate the complete capture of
