TUCSON, Ariz., Dec. 4, 2012 — Bruker Corp. has released a line of IRIS TERS probes. By enabling tip-enhanced Raman spectroscopy (TERS), the probe tips provide nondestructive label-free chemical detection at the nanoscale.
As sharp, solid-metal cones, the probes deliver high Raman enhancement, which translates to high sensitivity and spatial resolution. Together with the proprietary Innova-IRIS system and third-party research Raman systems, the probes create a complete commercial TERS solution.
With their proven TERS contrast capability, they move atomic force microscopy (AFM) beyond just imaging. All existing Innova-IRIS systems require only a new cartridge to start using the probes, and any existing Innova can be upgraded to an Innova-IRIS AFM/Raman system.
Used on the Innova-IRIS, the probes enable TERS on opaque samples using scanning tunneling microscopy feedback. Made of solid gold, they are optimized for high TERS enhancement at red and near-infrared Raman excitation wavelengths. They retain their high enhancement over a long shelf life.
