Abstract
In this paper a convenient and universal strategy for preparing nanoring arrays of different compositions based on a colloidal-crystal-template strategy is reported. Large-area arrays of polystyrene, magnetite, Au, Si, magnetite nanoparticle/polystyrene and Au/polystyrene double-layer composite nanorings are prepared. Many kinds of nanoring structures, including Fe3O 4 nanoparticle/polystyrene and Au/polystyrene double-layer nanorings, can be released from the substrates, resulting in free-standing composite nanorings, which might be used as self-assembly building blocks and ultrasensitive bio- and chemical sensors.
