Résumé
I will present some recent results on controlled experiments probing fluidic transport at the nanoscale. In particular, I will show how we use alternative routes to molecular confinement, which circumvents demanding nanofabrication steps, partially releases material constraints, and offers continuously tunable molecular confinements. These soft-matter-inspired approaches use wetting film that spontaneously condenses on a substrate or soap films that are intrinsically nanometric as versatile and tunable nanofluidic channels.
