New Nanoscale Imaging Method Finds Application in Plasmonics

Caption: Infrared laser light (purple) from below a sample (blue) excites ring-shaped nanoscale plasmonic resonator structures (gold). Hot spots (white) form in the rings' gaps. In these hot spots, infrared absorption is enhanced, allowing for more sensitive chemical recognition. A scanning AFM tip detects the expansion of the underlying material in response to absorption of infrared light.
