Figure 1. Reversible stomatocyte magnetic valve.

Figure 1

(a) Schematic representation of stomatocyte formation and reversible change in its membrane flexibility from glassy to the plasticized state in the presence of organic solvent. The stomatocyte formation takes place under dialysis in pure water (blue spheres). The change in the flexibility of the membrane of stomatocytes from glassy to flexible takes place under reverse dialysis conditions in a mixture of water (blue spheres) and organic solvent (red spheres). (b) Representation of the amphiphilic block-copolymer assembly in a bilayer and its chemical structure. (c) Schematic representation of the reversible and controlled capture and release of particles under magnetic field via opening and closing of polymeric stomatocytes in the magnetic field. The stomatocytes were obtained by dialysis from diamagnetic polymersomes.
