Abstract:
1. A method for fabricating surface-enhanced Raman scattering substrates including nanoparticles containing at least one material that enhances Raman scattering comprising the steps of: applying a nanoparticle ink to a surface of a substrate, wherein the nanoparticle ink comprises a liquid vehicle and a plurality of stabilized nanoparticles; heating the nanoparticle ink and the substrate in a first heating step to a first temperature for a first period of time to remove liquid vehicle; and heating the substrate and the plurality of stabilized nanoparticles in a second heating step at a second temperature higher than the first temperature for a second period of time to remove at least some of said stabilizer and form a nanoparticle layer on the substrate, wherein said second heating step is terminated when an amplification of the Raman scattering signal of from about 2×10
