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

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

High and low salinity water flooding are common oil recovery processes performed in the oil
fields for extracting crude oil from the reservoir. These processes are often performed …

The internal microenvironment of a living cell is heterogeneous and comprises a multitude of
organelles with distinct biochemistry. Amongst them are biomolecular condensates, which …

Phoresis of biocolloidal objects in response to chemical gradients is a matter of interest
among diverse scientific disciplines owing to their importance in the spatiotemporal …

We reveal a physical mechanism that enables the preconcentration, sorting, and
characterization of charged polystyrene nanobeads and liposomes dispersed in a …

The transport of nanoparticles in biological hydrogels is often hindered by the strong
confinement of the media, thus limiting important applications such as drug delivery and …

Recent experiments by Doan et al.(Nano Lett., 2021, 21, 7625–7630) demonstrated and
measured colloid diffusiophoresis in porous media but existing theories cannot predict the …

We present a microfluidic crossflow separation of colloids enabled by the dissolution of CO2
gas in aqueous suspensions. The dissolved CO2 dissociates into H+ and HCO3–ions …

The delivery of small particles into porous environments remains highly challenging
because of the low permeability to the fluids that carry these colloids. Even more challenging …
