Background:

  • The Defense Advanced Research Projects Agency (DARPA) Surface-Enhanced Raman Scattering (SERS) program aimed to advance nanometallic surface technology.
  • Evaluating the sensitivity and reproducibility of SERS substrates is critical for their practical application.

Purpose of the Study:

  • To establish an evaluation protocol for nanometallic SERS active surfaces.
  • To enable unambiguous comparison of sensitivity and reproducibility across different SERS substrates.
  • To develop analytical and spectroscopic figures of merit for SERS substrate assessment.

Main Methods:

  • Collaboration between U.S. Army Edgewood Chemical Biological Center and U.S. Army Research Laboratory-Aldelphi Laboratory Center.
  • Design and implementation of a standardized evaluation protocol.
  • Calculation of enhancement values for direct substrate comparison.
  • Collection of physical and spectral characterization data.

Main Results:

  • A robust evaluation protocol for SERS active surfaces was successfully developed and implemented.
  • The protocol allows for quantitative comparison of enhancement values across diverse SERS substrates.
  • The method accounts for variations in substrate fabrication and platform characteristics.

Conclusions:
