A model for sample stacking in microcapillary DNA electrophoresis
… electric field. The electric field drives the analyte transport. The analyte consists of DNA molecules of various fragment sizes. Since the DNA concentration is smaller than the electrolyte concentration by a few orders of magnitude, its concentration does not affect the conductivity. The major …

Fabrication, Metrology, and Transport Characteristics of Single Polymeric Nanopores in Three-Dimensional Hybrid Microfluidic/nanofluidic Devices
… volumes, short length scales, small numbers of analyte molecules, and new physical phenomena involved. To this end, robust and reproducible methods were developed to fabricate hybrid microfluidic/nanofluidic systems where single, high aspect ratio polymer nanopores (100 nm < d < 500 nm) provide …

Ion Transmission in the first vacuum stage of an Inductively Coupled Plasma Mass Spectrometer
… of atomic species to identify factors affecting analyte transport through the sampling orifice of the vacuum interface. Several non-idealities in the performance of the interface were found. (1) Operating conditions and sample compositions can negatively affect the efficiency with which ions are …

Methods for the Detection of Biological Analytes on Dendritic Surface-Enhanced Raman Scattering (SERS) Substrates
… and inconsistent results, stemming from low analyte concentration at SERS-active sites and irregular formation of “hotspots,” essential for signal enhancement. This doctoral research aims to develop a direct, sensitive SERS-based approach for detecting biological targets, such as proteins and …

The effects of organic gases on atomic spectrometric signals in the ICP
… high temperature promotes transitions of the analyte and the argon support gas making spectral interference a problem. To alleviate this problem in AFS, it was necessary to look higher in the plasma tail, now the entrainment of oxygen and the formation of metal oxides was thought to be …

Advanced Applications of Raman Spectroscopy for Environmental Analyses
… or separation protocol to extract the analyte from its matrix. Raman spectroscopy is unique in its ability to detect organic or inorganic, airborne or waterborne, and embedded or adsorbed analytes within environmental systems. This ability comes from the inherent abilities of the Raman …

Active transport and concentration of analytes in microfluidic paper based analytical devices using ion concentration polarization
… after becoming fully wet. In this work, active transport and concentration of analytes in fully wet paper-based assays is demonstrated by leveraging ion concentration polarization (ICP). The efficacy of ICP-inducing µPADs is demonstrated through transporting and concentrating dye, fluorescein …
