We report the unconventional space-free confined growth of Au nanoshells with well-defined plasmonic properties and active tuning their plasmon coupling by nanoscale magnetic assembly. The seeded exclusively occurred at hard-soft interfaces between Fe3O4 core phenolic resin without need creating a limiting space, which represents general elegant approach to various core-shell nanostructures. deformability permeable layers plays an essential role in regulating interfacial nanoshells. While polymer elasticity suppresses radial deposition atoms, high can afford enough spaces for formation conformal metallic shells. coupled magnetic-plasmonic allow resonant scattering assembly hybrid nanoparticles into chains, whose potentials applications have been demonstrated designing transparent displays anticounterfeiting devices.
