D., Massachusetts Institute of Technology, Department of Materials Science and Engineering, June 2013. This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections. Cataloged from student-submitted PDF version of thesis. "June 2013." Includes bibliographical references. Dense networks of high aspect ratio nanowires can provide important functionality to electronic devices through a unique combination of electronic and structural properties including high conductivity, high surface area, and tunable porosity. In this thesis, we explore the virus-enabled synthesis and two/three-dimensional assembly of metallic and semiconducting nanowire networks for future applications including batteries and solar cells. In Chapter 2, we describe the virus-enabled synthesis of titanium oxide nanowires and their incorporation in layer-by-layer polyelectrolyte assemblies for use in dye sensitized solar cells. In Chapter 3, we describe a two-dimensional network of virus-templated cobalt oxide nanowires integrated into ultrathin microbatteries via soft lithography. In Chapter 4, we describe a three-dimensional porous virus-only aerogel network and demonstrate a virus-assembled metal nanowire network for use in batteries. Finally, in Chapter 5, the mechanical properties of various virus assembled three-dimensional structures are measured and compared. We hereby expand the virus assembly toolkit and demonstrate the versatility of bioengineered materials templates. by Forrest W. Liau.
