The use of tools can be traced back to the beginning of recorded history and represents a
significant step in the evolution of mankind. A machine is a tool that can perform intended …

Conspectus Micro-and nanomotors are nonliving micro-and nanoparticles that are rendered
motile by supplying energy from external sources, for example, through asymmetric …

We report a magnetically actuated peanut-shaped hematite colloid motor that can not only
move in a rolling or wobbling mode in fluids but also perform single cell manipulation and …

Spatiotemporally controlled active manipulation of external micro‐/nanoprobes inside living
cells can lead to development of innovative biomedical technologies and inspire …

Magnetic nanomotors (MNMs), powered by a magnetic field, are ideal platforms to achieve
versatile biomedical applications in a collective and spatiotemporal fashion. Although the …

Controlled motion of artificial nanomotors in biological environments, such as blood, can
lead to fascinating biomedical applications, ranging from targeted drug delivery to …

Millions of root canal treatments fail worldwide due to remnant bacteria deep in the dentinal
tubules located within the dentine tissue of human teeth. The complex and narrow geometry …

This paper studies the behavior of rotating magnetic microrobots, constructed with a
permanent magnet or a soft ferromagnet, when the applied magnetic field rotates faster than …

Magnetic nanoparticles are widely applied in biochemical applications due to their diverse
functionalization and fast response to external magnetic fields. However, when actuated by …

Locomotion in fluids at the nanoscale is dominated by viscous drag. One efficient propulsion
scheme is to use a weak rotating magnetic field that drives a chiral object. From bacterial …
