In article number 2003912, Simone Schuerle, Nima Mirkhani, and Michael G. Christiansen highlight the promise of magnetotactic bacteria as flow mediators under time-varying magnetic fields. Selective drug delivery is a potential application made feasible by their unique magnetic and hydrodynamic properties. Superimposing a magnetostatic selection field with a uniform rotating magnetic field is shown as a suitable control strategy for targeted actuation of bacteria in the zero field region. Ultimately, such a control strategy may provide a means to enhance selective transport of co-injected or conjugated drugs while mitigating off-target effects.
