This Perspective accounts for recent progress in the directed control of interfacial fluid flows
harnessed to assemble architected soft materials. We are focusing on the paradigmatic …

The dynamics of a flexible filament sedimenting in a viscous fluid are explored analytically
and numerically. Compared with the well-studied case of sedimenting rigid rods, the …

The observations of microorganisms revealed how they swim. As inspired by them, studies
on artificial micro-robots with various actuation mechanisms have been thriving. To elucidate …

Two bodies resting at a fluid interface may interact laterally due to the surface deformations
they induce. Here we use an applied magnetic force to perform direct measurements of the …

We investigate the dynamics of a dilute suspension of hydrodynamically interacting motile or
immotile stress-generating swimmers or particles as they invade a surrounding viscous fluid …

Lamellar supramolecular assemblies are a common feature of fibrous gels formed by
molecules such as peptides and ureas. Competition between gelation and crystallization is …

The transport of deformable particles through porous media underlies a wealth of
applications ranging from filtration to oil recovery to the transport and spreading of biological …

An analytical expression for the fluctuation-rounded stretch-coil transition of semiflexible
polymers in extensional flows is derived. The competition between elasticity and tension is …

We report on the elastocapillary deformation of flexible microfibers in contact with liquid
droplets. A fiber is observed to bend more as the size of the contacting droplet is increased …

The complex dynamics of elastic fibers in viscous fluids are central to many biological and
industrial systems. Fluid–structure interactions underlying these dynamics govern the shape …
