Plasmonic Nanomaterials-Based Point-Of-Care Biosensors, Rohit Gupta
Plasmonic Nanomaterials-Based Point-Of-Care Biosensors, Rohit Gupta
McKelvey School of Engineering Theses & Dissertations
Point-of-care (POC) biosensors, although rapid and easy-to-use, are orders magnitude less sensitive than laboratory-based tests. Further they are plagued by poor stability of recognition element thus limiting its widespread applicability in resource-limited settings. Therefore, there is a critical need for realizing stable POC biosensors with sensitivity comparable to gold-standard laboratory-based tests. This challenge constitutes the fundamental basis of this dissertation work– to expand access to quality and accurate biodiagnostic tools. At the heart of these solutions lies plasmonic nanoparticles which exhibit unique optical properties which are attractive for label-free and labelled biosensors.Firstly, we improve the stability and applicability of label-free …
First-Principles Studies Of Anion Engineering In Functional Ceramics, Steven Timothy Hartman
First-Principles Studies Of Anion Engineering In Functional Ceramics, Steven Timothy Hartman
McKelvey School of Engineering Theses & Dissertations
Ceramic materials display a wide variety of valuable properties, such as ferroelectricity, superconductivity, and magnetic ordering, due to the partially covalent bonds which connect the cations and anions. While many breakthroughs have been made by mixing multiple cations on a sublattice, the equivalent mixed-anion ceramics have not received nearly as much attention, despite the key role the anion plays in the materials’ properties. There is great potential for functional ceramics design using anion engineering, which aims to tune the materials properties by adding and removing different types of anions in existing classes of ceramic materials. In this dissertation, I present …
