Diffusiophoresis is the spontaneous motion of particles under a concentration gradient of
solutes. Since the first recognition by Derjaguin and colleagues in 1947 in the form of …

Osmosis is a universal phenomenon occurring in a broad variety of processes and fields. It
is the archetype of entropic forces, both trivial in its fundamental expression–the van't Hoff …

Fluid transport that is driven by gradients of pressure, gravity, or electro-magnetic potential is
well-known and studied in many fields. A subtler type of transport, called diffusiophoresis …

Light-activated self-propelled colloids are synthesized and their active motion is studied
using optical microscopy. We propose a versatile route using different photoactive materials …

We study experimentally the effect of added salt in the phoretic motion of chemically driven
colloidal particles. We show that the response of passive colloids to a fixed active colloid, be …

Electrolytic diffusiophoresis is the movement of colloidal particles in response to a
concentration gradient of an electrolyte. The diffusiophoretic velocity vDP is typically …

A colloidal particle placed in an inhomogeneous solution of smaller nonadsorbing polymers
will move towards regions of lower polymer concentration in order to reduce the free energy …

Equilibrium interactions between particles in aqueous suspensions are limited to distances
less than 1 μm. Here, we describe a versatile concept to design and engineer …

Osmosis across membranes is intrinsically associated with the concept of semipermeability.
Here, however, we demonstrate that osmotic flow can be generated by solute gradients …

Diffusiophoresis is the spontaneous motion of colloidal particles induced by the presence of
a local solute concentration gradient, and diffusioosmosis is the analogous motion of fluid …
