We propose a mechanism for restoration of collapsed structures using critical Casimir forces by investigating the diffusion of metal flake-like particles. By tuning temperature near-criticality and employing selective self-assembled monolayers the resulting repulsive critical Casimir force is large enough to lift off particle and enable transitions previously impeded by QED Casimir attraction.
A metal flake is hovering above a glass surface on top of which a metal substrate has been sputtered and treated a posteriori with a self-assembled monolayer.
