A) SEM image of a quasi-3D plasmonic crystal Upper inset: low-resolution optical image illustrating the diffraction colors produced by these structures. Lower inset: high magnification SEM showing the upper and lower levels of gold. B) Schematic illustration of the normal incidence, transmission mode geometry used to probe these devices. Inset: Close-up schematic illustration of the crystal.

FS-MRL PIs Ralph Nuzzo and John Rogers along with their group members and collaborators at Argonne National Laboratory had the article "Quantitative multispectral biosensing and 1D imaging using quasi-3D plasmonic crystals" published in the November 14 issue of PNAS, the Proceedings of the National Academy of Sciences. The groups highlighted a class of quasi-3D plasmonic crystal consisting of multilayered, regular arrays of subwavelength nanostructures whose optical transmission spectra are especially well suited for sensing applications.

This work in turn was cited as a research highlight at the website for new journal Nature Nanotechnology, discussing the highly sensitive sensors that may be created from the groups' low-cost crystal arrays. This journal was launched in October 2006 by Nature Publishing Group and according to their website is "a multidisciplinary journal that publishes papers of the highest quality and significance in all areas of nanoscience and nanotechnology. The journal covers research into the design, characterization and production of structures, devices and systems that involve the manipulation and control of materials and phenomena at atomic, molecular and macromolecular scales."

Additionally, another Rogers group project is featured in the December 2006 issue of Nature Nanomaterials with an article entitled "Controlled buckling of semiconductor nanoribbons for stretchable electronics".
