Séchage sans gradients de concentration, même dans de grandes gouttes microfluidiques

publié le

In most situations, drying is accompanied by the development of strong concentration gradients. Here, we
evidence theoretically and experimentally that there exist microfluidic geometries for which confined drying
becomes homogeneous, i.e., with no concentration gradient regardless of the type of solute involved in
the process ; ions, molecules, and colloids do concentrate in the same way providing a limited set of
assumptions concerning the microfluidic geometry. It thus makes possible the establishment of phase
diagrams of multi-component mixtures at the nanoliter scale.
