Compartmentalization Of Dna-Based Molecular Computing Elements Using Lipid Bilayers, Aurora Fabry-Wood

Biomedical Engineering ETDs

This dissertation will present a progression from the detection of double-stranded DNA using a combination of toehold-mediated strand displacement and DNAzyme reactions in dilute saline solutions, to the generation of separate compartments to allow standardization of DNA computing elements, by protecting from complementary strands. In well-mixed solutions complementary regions cause spurious interactions. Importantly, these compartments also provide protection from nucleases. Along the way we will also explore the use of silica microsphere supported lipid bilayers to run compartmentalized DNA reactions on a fluid surface and the design of a molecule capable of DNA-based transmembrane signal transduction.
