Microfabrication Of Bio-Analytical Devices: Microelectrode Array And Traveling-Wave Electrophoresis, Neil Draper

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The need for potable water is increasing with the ever-increasing world population. Further development of fast, portable, and cost effective analytical tools is necessary in order to create diagnostic techniques capable of supporting the water needs of the world’s population. Within the last decade microfluidics and Lab-on-a-Chip (LOC) technologies have increased the portability and speed of detection for aqueous samples. Photolithography techniques serve as a cost effective fabrication tool to create LOC electrodes on the micron scale.

An in-depth look at the fabrication process is undertaken in this paper in order to further the development of micro-scale detection techniques. An …

Microfabrication Of Electrochemical Analytical Devices For Detection Of Pathogen Species Dna And Toxic Metal Ions, Spencer Williams

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Water quality is a crucial factor in determining the health of an environment, and in turn the health of all those living in the given environment. Early detection of potential hazards in source water used for drinking would help to avoid outbreaks of sickness and even death. Contaminants, found in contact and drinking water, having negative effects on human health may include pathogenic microorganisms, and metal ion pollutants such as lead or cadmium. Lead and cadmium were selected due to well-known electrochemical properties providing easy references for developing new detection devices. Current methods for detection of these contaminants are extremely …
