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 …

In this review, we cover recent advances in microfluidic colloid separation enabled by
diffusiophoresis. Diffusiophoresis describes the motion of colloidal particles induced by local …

Turing patterns are fundamental in biophysics, emerging from short-range activation and
long-range inhibition processes. However, their paradigm is based on diffusive transport …

Chemical gradients, the spatial variations in chemical concentrations and components, are
omnipresent in environments ranging from biological and environmental systems to …

Microtubules are dynamic filaments that assemble spindles for eukaryotic cell division. As
the concentration profiles of soluble tubulin and regulatory proteins are non-uniform during …

Recent experimental studies have utilized AC electric fields and electrochemical reactions in
multicomponent electrolyte solutions to control colloidal assembly. However, theoretical …

The charging of electrical double layers inside a cylindrical pore has applications to
supercapacitors, batteries, desalination and biosensors. The charging dynamics in the limit …

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 …

The ability to sense chemical gradients and respond with directional motility and chemical
activity is a defining feature of complex living systems. There is a strong interest among …

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