SERS-active nanoparticles as a barcoding technology for tags and seals
- Los Alamos National Laboratory
- SNL
In this paper, we present our work to modernize tagging and sealing technologies for international safeguards applications. Our work combines technologies developed at both Los Alamos National Laboratory (LANL), and Sandia National Laboratories (SNL), to offer a passive tag and seal system that can be applied and verified in field, with minimal training for on-site personnel, along with a low per-seal cost. Here, we focus primarily on LANL technology: the use of Surface Enhanced Raman Scattering (SERS) as an inexpensive verification tool. Our nanoparticles offer unique SERS responses, which we can then use to incorporate robust barcoding into tag materials. We describe this technology in more detail, offer preliminary results, and outline integration with SNL developments.
