Abstract
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.
