Utilizing Nanostructures And Nano-Mechanics For Sensitive Analyte Detection Via Surface Enhanced Raman Spectroscopy (Sers) And Micro-Cantilever Sensing Platforms, Ryan Andrew Wallace

Doctoral Dissertations

The purpose of this dissertation is to present the effective utilization of nano-structures and nano-mechanics in conjunction with surface enhanced Raman spectroscopy (SERS) and micro-cantilever (MC) mechanical sensors for sensitive analytical detection. One of the most important attributes an Analytical Chemist can possess is the ability to develop and efficiently use the tools provided to obtain precise and accurate information that can be effectively communicated. The following is a brief outline of the background concepts and studies that will be present herein.

A discussion of SERS will be presented in which the history and concepts behind the technique will be …

The Fabrication Of Micro- And Nano- Scale Deterministic And Stochastic Pillar Arrays For Planar Separations, Teresa Byers Kirchner

Doctoral Dissertations

Planar chromatography, unlike high performance liquid chromatography (HPLC), has not experienced a significant evolution in stationary phase media since the development of the technique. This has lead HPLC to become a much more popular and robust analytical method. Main factors that contribute to improved performance of chromatographic systems include a reduction in particle size, homogeneity of the stationary phase, and an increase in velocity of the mobile phase. In general, a reduction in particle size should lead to an improvement in the performance of all chromatography systems. However, the main obstacle of improving the performance of planar chromatography systems is …
