Magnetically propelled MOFBOTs perform microrobotic drug delivery (w/video)

By applying concepts developed in micro- and nanorobotics, researchers demonstrate the controlled motion and delivery of cargo payloads embedded in metal-organic frameworks (MOFs). The helical MOF-based micromachine, propelled by artificial bacterial flagella, can swim and follow complex trajectories in three dimensions under the control of weak rotational magnetic fields. These swimmers are tumor-responsiv and can act as selectively automated and targeted drug delivery platforms.
