Abstract
One embodiment is a SERS enhancing substrate which includes a porous substrate and a Raman enhancing material associated with a surface of the porous substrate. The Raman enhancing material may be a Raman enhancing metal or other Raman enhancing material. The Raman enhancing material may also be configured to improve binding of a taggant to the substrate. The substrate described above may be included in a sample vessel useful for the flow-through analysis of large sample volumes, or for the rapid analysis of very dilute samples. Other embodiments include methods and systems for detecting taggants with SERS and similar techniques.
