A vesicle is held in place with a DEP pixel while a tether is pulled using the magnetic matrix. The yellow square shows the DEP pixel that is activated, and the red lines show the magnetic wires that are turned on. There are iron-oxide nanoparticles suspended in the solution inside the vesicle. After the first frame (a) the magnetic field is turned off and the tether is pulled back into the vesicle. Each frame (a-f) is separated by 0.2 seconds.
