Diffusiophoretic migration of colloidal particles in sucrose gradients
Antoine Monier, Brielle Byerley, Julien Renaudeau +3
Diffusiophoresis (DP) refers to the migration of particles driven by a solute concentration gradient in a liquid. Observations in the case of molecular neutral solutes are rather s…

Fluorescent molecular rotor-based polymer materials for local microviscosity mapping in microfluidic channels
Dharshana Nalatamby, Florence Gibouin, Maxime Zitouni +5
A viscosity-sensitive monomer consisting of a methacrylate-functionalized julolidone-based molecular rotor (MECVJ) was synthesized and used to obtain viscosity-sensitive polymers (…

Transient osmotic flows in a microfluidic channel: measurements of solute permeability and reflection coefficients of hydrogel membranes
Julien Renaudeau, Pierre Lidon, Jean-Baptiste Salmon
We first highlight theoretically a microfluidic configuration that allows to measure two fundamental parameters describing mass transport through a membrane: the solute permeabilit…
