Photophysical Studies Of Electronic Structure And Excited-State Dynamics Of Dna-Templated Cyanine Dye Aggregates, Jonathan Samuel Huff

Boise State University Theses and Dissertations

The invention and widespread adoption of the digital computer in the last century has led to an era of rapid technological advancement that has continued to the present day. This advancement has been sustained to a large degree by continued miniaturization of the electronic components in microprocessors, which results in increased computing power and energy efficiency. In recent years, this strategy has produced diminishing returns because the cost for each incremental size reduction increases as engineers approach the fundamental scaling limits of silicon-based semiconductor devices. Meanwhile, breakthroughs in DNA nanotechnology hold great promise for a new generation of self-assembled nanodevices …

An All-Optical Excitonic Switch Templated On A Dna Scaffold Operated In The Liquid And Solid Phases, Donald L. Kellis

Boise State University Theses and Dissertations

The natural excitonic circuitry of photosynthetic organisms, including light harvesting antennas, provides a distinctive example of a highly attractive bio-inspired alternative to electronic circuits. Excitonics, which capitalizes on spatially arranged optically active molecules ability to capture and transfer light energy below the diffraction limit of light has garnered recognition as a potential disruptive replacement for electronic circuits. However, assembly of optically active molecules to construct even simple excitonic devices has been impeded by the limited maturity of suitable molecular scale assembly technologies.

An example of nanophotonic circuitry, natural light harvesting antennas employ proteins as scaffolds to organize and self-assemble light-active …

Optically Active Dye-Based Systems Templated By Dna Exhibiting Excitonic Delocalization, Brittany Lynn Cannon

Boise State University Theses and Dissertations

The concept of quantum computing was first developed in the early 1980’s. The attraction of quantum computers is their potential capacity to solve extremely complex problems, such as factorization, on a timescale far faster than that of classical computers. However, realization of quantum computation is currently in its infancy, and recent implementations possess serious drawbacks that reduce their appeal. Some challenges of current designs include the necessity to cool the systems using liquid helium to near absolute zero temperatures (15 mK) in order to maintain sufficiently long-lifetimes of the Qbits (i.e., unit of quantum information), difficulty with scaling up the …

Improving The Selectivity And Reducing The Leakage Of Dna Strand Displacement Systems, Shohei Kotani

Boise State University Theses and Dissertations

Because of the elegance of Watson-Crick base pairing and the programmability of toehold-mediated strand displacement, DNA is a model material for designing, building, and testing molecular assemblies. DNA assemblies are categorized as structural when they are at thermodynamic equilibrium and dynamic when they are not. Through programmed perturbations, metastable assemblies perform physical, chemical, and computational work. When integrated into a diagnostic package, disease-specific nucleic acid sequences can be identified, amplified, and analyzed via standard DNA nanotechnology rules. In order for these rules to make an impact, two critical challenges in the field have been undertaken in this dissertation. First, the …
