Masters Theses
"Surface-enhanced Raman scattering has many applications to chemical science, and shows great promise in the medical field because of its ability to provide "molecular fingerprinting" of probe molecules, whereby a material can be identified and potentially quantified. This is done by enhancing the normally weak Raman spectrum by many orders of magnitude with the use of fabricated substrates. It is therefore desirable to produce repeatable substrates with high enhancement factors for identification and quantification of samples. This thesis introduces a new method for generating such a substrate. By using femtosecond laser machining, gold sputtering, and nanosecond laser annealing, gold nanoparticles …
