Fall 2014
Developing a simple, general, and isothermal self-replicating system is one of the key requirements for a simplified detection platform for nucleic acid sequences specific to a disease causing microrganism. One of the challenges in achieving nucleic-acid templated isothermal amplification is that...

Optical imaging of membrane potentials has become an immensely popular approach to study neuronal activity. Over the past decades, a number of voltage indicators have been introduced including the voltage sensitive fluorescent protein (VSFP) and microbial rhodopsins. However, most of these...

Tuning the Surface Composition, Spatial Arrangement, and Thermal Release Behavior of DNA-Gold Nanomaterials
DownloadFall 2013
Combining multiple functions and controlling their relative organization on the surface, as well as controlling the release of payloads will be essential properties of nanomaterials for future medical applications. In this thesis we studied these properties using as a model DNA-gold...

Tuning π-Conjugated Polymers with Heteroatoms: Synthesis of Polytellurophenes and Soluble Polyacetylenes
DownloadFall 2021
This Thesis describes the synthesis and investigation of π-conjugated oligomers and polymers with optoelectronic properties affected by the presence of a heteroatom. Two major classes of polymers are discussed: 1) polytellurophenes, where the backbone is formed by 5-membered heterocycles...

Fall 2012
5-Membered carbocycles are ubiquitous in natural products and synthetic drugs. Methods of generating them are therefore valuable, and the ability to do so in a stereospecific and enantioselective manner while making considerable gains in molecular complexity with additional incorporation of...

Unlocking the Hidden Potential of Cobalt: Hydrodeoxygenation of Aromatic Ketones by Cobalt Clusters
DownloadFall 2017
Cobalt phosphoranimide clusters [Co(NPPh3)(OSiMe3)(THF)]2, [Co(NPPh3)(OtBu)(THF)]2 and [Co(NPiPr3)2]3 were synthesized. Salt metathesis between CoBr2 and NaNPPh3 and a subsequent in situ reaction with KOSiMe3 provides a convenient and scalable preparation of [Co(NPPh3)(OSiMe3)(THF)]2. The same...
