Metamaterials have all kinds of funky properties. Most famously they can be used as 'invisibility cloaks' and can have a negative refractive index. Potential applications include super-lenses, beam steerers, modulators, band-pass filters and antenna systems. 
Metamaterials consist of hierarchically organised periodic structures (on micro/nanometer length scales according to the wavelength of light).
Svaya's nanoreactor technology, since it allows control the size, density and (most importantly) 3D distribution of metallic and semiconductor nanoparticles could be used for bottom-up construction of metamaterials.
"If you want a bulk metamaterial for visible and infrared light, you need to embed particles of silver or gold inside a dielectric, and you need to do it in 3D, with high resolution." 
Metamaterials are currently made by a number of techniques, mostly based on nanolithography.
Hm, very interesting. The quote certainly seems to make this a great use-case. A few questions that come to mind at first blush:
If plausible, certainly kickass :-)
The most accessible application for metamaterials is probably Superlenses. Here's a layered UV planar lens http://www.nist.gov/cnst/20130523_flatlens.cfm
