Liu, Gang Logan Xu, Zhida 2011-08-25T22:15:15Z 2011-08-25T22:15:15Z 2011-08-25T22:15:15Z 2011-08 Surface-enhanced Raman spectroscopy (SERS) has been increasingly utilized as an analytical technique with significant chemical and biological applications due to its high sensitivity, selectivity and accuracy. As nanotextured surfaces play a key role in SERS, production of highly sensitive, low cost, uniform, high throughput and biologically compatible SERS substrates and evaluation of the performance of SERS substrates remain as important issues for industrialization of SERS. This thesis presents the fabrication, modeling and characterization of two kinds of SERS substrates: one has a nanoconic surface structure, which we call black silver, and the other consists of plastic replica molded pyramids, which we call SERS pyramids. The Raman enhancement factor is calculated as 6.38$\times$10$^7$ for black silver and 1.6$\times$10$^6$ for SERS pyramids. In addition, two exemplary applications of black silver SERS substrates---the detection of contaminants leached from lab-use plasticware and peptide label-free sensing---are demonstrated.
