An interesting paper by Anatoly Zayats group. I had the opportunity to meet A. Zayats at the APS meeting in 2008, in New Orleans.
A. V. Kabashin et al. Plasmonic nanorod metamaterials for biosensing. Nature Materials 8, 867 - 871 (2009).
The authors demonstrate an improvement in biosensing technology using a plasmonic metamaterial that is capable of supporting a guided mode in a porous nanorod layer. [...]
Here, we notice that there's not much innovation as far as design is concerned, but the concept is new. We have entered in an era where we have complete understanding how to design metamaterials. Our limitation resides in the ability to manufacture (micro-/nanofabricate) them. And, the future of metamaterials lies in applications, in particular life sciences applications .
