Accessing both electrochemical SEIRA and SERS with ultrasensitive metamaterials for enhanced molecular identification
Nicolas Spiesshofer, Tabitha Jones, Sarah May Sibug Torres +11
Surface-enhanced IR absorption (SEIRA) and surface-enhanced Raman spectroscopy (SERS) are complementary techniques that allow for ultrasensitive chemical fingerprinting. Non-invasi…

Extreme mid-infrared field enhancement and anapoles in high-index plasmonic metamaterials
Zoltan Sztranyovszky, Nicolas Spiesshofer, Caleb Todd +5
High-refractive-index materials underpin a wide range of optical technologies, including communications, imaging, lasers, and integrated photonic systems. Here, we demonstrate a se…
