Please join Mark Anderson, Principal Chemist at Caltech’s Jet Propulsion Lab (JPL), NASA, to hear about how, for the first time, simultaneous SERS and SEIRA have been measured from the same spot and the same time with the same submicron resolution, resulting another first –single molecule detection with SEIRA, enabled by photothermal detection.

DATE & TIME
📆 Thursday, April 20th, 2023
🕔 11:00 – 12:00 (CET)

Mark Anderson will present results from his recent paper entitled, “Concurrent surface enhanced infrared and Raman spectroscopy with single molecule sensitivity”, with the new and significant aspects of this work as follows:

A summary of the webinar includes:

• • Concurrent, simultaneous acquisition of SEIRA and SERS from the same plasmonic hotspot
  • Acquisition of simultaneous infrared and Raman spectra from a single molecule or molecular cluster
  • Demonstration of a dual enhancement for SEIRA, wherein the photothermal optical probe and the infrared absorption are both enhanced, enabling very sensitive, photothermally detected SEIRA, down to the single molecule
  • Application of dual SEIRA and SERS to interrogate material collected from a surface onto an atomic force microscope tip

Dr. Mustafa Kansiz, Director of Product Management and Marketing at PSC, will provide a brief technique overview, comparisons to traditional IR and Raman spectroscopy, covering submicron simultaneous IR+Raman together with a range of application examples in this two part event.
