Medical micro/nanorobots have received tremendous attention over the past decades owing
to their potential to be navigated into hard-to-reach tissues for a number of biomedical …

Active matter, which ranges from molecular motors to groups of animals, exists at different
length scales and timescales, and various computational models have been proposed to …

Untethered microrobots offer a great promise for localized targeted therapy in hard-to-
access spaces in our body. Despite recent advancements, most microrobot propulsion …

The locomotion of microorganisms and spermatozoa in complex viscoelastic fluids is of
critical importance in many biological processes such as fertilization, infection, and biofilm …

We review the literature on swimming in complex fluids. A classification is proposed by
comparing the length-and timescales of a swimmer with those of nearby obstacles …

Run-and-tumble motility is widely used by swimming microorganisms including numerous
prokaryotic and eukaryotic organisms. Here, we experimentally investigate the run-and …

In the last two decades, advances in micro‐and nanofabrication have enabled the
development of a wide variety of active or “self‐propelling” microparticles, which convert …

We review recent work on active colloids or swimmers, such as self-propelled
microorganisms, phoretic colloidal particles, and artificial micro-robotic systems, moving in …

The motility of microorganisms is influenced greatly by their hydrodynamic interactions with
the fluidic environment they inhabit. We show by direct experimental observation of the bi …

By now active Brownian motion is a well-established model to describe the motion of
mesoscopic self-propelled particles in a Newtonian fluid. On the basis of the generalized …
