21_17/2009Ordered Gold Nanoarrays: 3D Ordered Gold Strings by Coating Nanoparticles with Mesogens (Adv. Mater. 17/2009)

Liquid-crystal-coated gold nanoparticles exhibit 3D long-range ordering in strings jacketed by rod-like mesogens (shown in green) with controllable interparticle spacing. The work reported on p. 1746 by Goran Ungar and co-workers demonstrates a new method of assembling ordered metal nanoparticle superlattices, in a step towards developing self-assembled metamaterials. The cover shows red, yellow, and blue nanoparticles lying at different heights and forming a rhombohedral lattice.
