Plasmonic crystal optics: Highly uniform, fully 3D plasmonic crystals exhibiting exceptional analytical sensitivity at visible wavelengths can image surface binding events with high spatial resolution and can distinguish adsorbates with masses that differ by only 25 amu. The picture shows a transmitted white-light plasmonic image of microcontact-printed lines (ca. 8 μm wide) of 1-octadecanethiol on the Au surface of a 3D plasmonic crystal.
