Description

Imaging the movement of microinjected GFP-functionalized magnetic nanoparticles (green) inside ovarian cancer cells that have a labelled actin cytoskeleton (red). These nanoparticles are controlled by magnetic force (sharp magnetig tip visible as "black shadow" on the right).

The movement of the magentic tip ("black shadow") triggers the movement and concentration of nanoparticles towards the magnet.
