Self-Assembled Dna Origami Templates For The Fabrication Of Electronic Nanostructures, Elisabeth Pound Gates Sep 2013

Self-Assembled Dna Origami Templates For The Fabrication Of Electronic Nanostructures, Elisabeth Pound Gates

Theses and Dissertations

An important goal of nanoscience is the self-assembly of nanoscale building blocks into complex nanostructures. DNA is an important and versatile building block for nanostructures because of its small size, predictable base pairing, and numerous sequence possibilities. I use DNA origami to design and fold DNA into predesigned shapes, to assemble thin, branched DNA nanostructures as templates for nanoscale metal features. Using a PCR-based scaffold strand generation procedure, several wire-like nanostructures with varying scaffold lengths were assembled. In addition, more complex prototype circuit element structures were designed and assembled, demonstrating the utility of this technique in creating complex templates. My ...


Metallization Of Dna And Dna Origami Using A Pd Seeding Method, Yanli Geng Jan 2013

Metallization Of Dna And Dna Origami Using A Pd Seeding Method, Yanli Geng

Theses and Dissertations

In this dissertation, I developed a Pd seeding method in association with electroless plating, to successfully metallize both lambda DNA and DNA origami templates on different surfaces. On mica surfaces, this method offered a fast, simple process, and the ability to obtain a relatively high yield of metallized DNA nanostructures. When using lambda DNA as the templates, I studied the effect of Pd(II) activation time on the seed height and density, and an optimal activation time between 10 and 30 min was obtained. Based on the Pd seeds formed on DNA, as well as a Pd electroless plating solution ...
