The nominating institution ETH Zurich on the breakthrough:
Pulling drug carriers with magnetic fields is difficult to scale up to humans. Schuerle developed a different control strategy using a combination of two fields: one that makes micro-magnets rotate, and a stationary field that limits this effect to the target site. The best micro-magnets for the job turn out to be made by nature: magnetotactic bacteria.
