Response of fluorescent molecular rotors in ternary macromolecular mixtures
Mingshan Chi, Anh-Thy Bui, Pierre Lidon +1
For a few decades, Fluorescent Molecular Rotors have been commonly employed as local probes of microviscosity in complex materials. However, without proper calibration, relating mi…
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…
