Overview

Magnetic manipulation, positioning, agitation and mixing of ultrasmall liquid volumes has been realized utilizing superparamagnetic beads in giant unilamellar vesicles. In the absence of any magnetic field the beads align to form extended chains while a rotating magnetic field provokes the chains to break up into smaller fragments caused by the interplay of viscous friction and magnetic attraction.
