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 …

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 …

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 experimentally study the motion of light-activated colloidal microswimmers in a
viscoelastic fluid. We find that, in such a non-Newtonian environment, the active colloids …

Microscale propulsion impacts a diverse array of fields ranging from biology and ecology to
health applications, such as infection, fertility, drug delivery, and microsurgery. However …

We experimentally study the dynamics of active particles (APs) in a viscoelastic fluid under
various geometrical constraints such as flat walls, spherical obstacles and cylindrical …

Self-diffusiophoresis of synthetic Janus (Si/Pt) microspheres in the presence of hydrogen
peroxide in complex environments is here investigated. We aim to address the single …

The hydrodynamic behavior of a squirmer swimming in the flow of power-law fluid is studied
numerically with an immersed boundary-lattice Boltzmann method. The power-law fluids …

In this review, we focus on recent experimental research involving active colloidal particles
of non-biological origin evolving in non-Newtonian fluids. This includes self-propelling active …

Swimming at the microscale typically involves two modes of motion: mechanical propulsion
and propulsion due to field interactions. During mechanical propulsion, particles swim by …
