Vertical segregation in the self-assembly of nanoparticles at the liquid/air interface.
Vertical segregation was induced by the size-dependent charge neutralization during the one-step interfacial self-assembly of colloidal gold nanoparticles with bimodal size distribution. This self-assembly approach also can assemble particles with tunable compositions into layered films.
