Microfabrication Of Electrochemical Analytical Devices For Detection Of Pathogen Species Dna And Toxic Metal Ions, Spencer Williams
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 …
In Vitro, Non-Invasive Imaging And Detection Of Single Living Mammalian Cells Interacting With Bio-Nano-Interfaces, Qifei Li
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Study of bio-nano-interfaces of living mammalian cells will help the identification of cellular alterations (e.g. nucleic acids, amino acids, biomechanics, etc.) due to external stimuli, the design of biomaterials (e.g. nanoparticles, nanotubes) and the investigation on the interaction between cells and bio-nano-interfaces (e.g. cell differentiation on 3D nanostructured materials). The chemical, physical, and mechanical changes of mammalian cells interacting with biomaterials can be investigated by analytical techniques. In this dissertation, cellular responses and property changes are evaluated by non-invasive spectroscopic technique, Raman microscopy (RM), and atomic force microscopy (AFM) combined with traditional biological methods. This dissertation includes the biophysical, biochemical …
