18_24b/2008Inside Front Cover: A Universal Approach to Fabricate Various Nanoring Arrays Based on a Colloidal-Crystal-Assisted-Lithography Strategy (Adv. Funct. Mater. 24/2008)

Bai Yang and co-workers report a novel method to fabricate nanoring structures from a wide variety of materials on page 4036. Large-area arrays of polystyrene (PS), magnetite, Au, Si, Fe3O4 nanoparticle/PS, and Au/PS double-layer composite nanorings are successfully prepared. Most of the nanorings fabricated by this method can be lifted off the substrate, resulting in free-standing nanorings, which show interesting and important applications as magnetic scaffolds for tissue engineering, self-assembly building blocks, ultra-sensitive sensors, or as imaging agents.
