520 $a This dissertation describes a series of experiments aimed at developing new synthetic methods towards DNA-modified nanostructured materials, and it also explores new schemes for the 'bio-inspired' rational assembly of such materials.
520 $a In Chapter 2, a novel trithiol-capped oligodeoxyribonucleotide and its related gold nanoparticle conjugates were synthesized. These DNA-gold nanoparticle conjugates exhibit substantially higher stabilities than analogues prepared from monothiol and cyclic disulfide-capped oligodeoxyribonucleotides, respectively, but comparable hybridization properties. In addition, this novel trithiol oligodeoxyribonucleotide can be used to stabilize particles larger than 30 nm in diameter, which are essential for many diagnostic applications.
520 $a In Chapter 3, a general solid-phase synthetic strategy for producing a novel class of DNA block copolymer amphiphiles is described. The assembled spherical micelle nanostructures exhibit recognition properties defined by their DNA sequences and can also be used to build higher-ordered structures through hybridization with nanomaterials that possess complementary DNA.
520 $a In Chapter 4, the design and synthesis of a new class of gold nanoparticle with guanosine monophosphate derivates or G-rich oligonucleotides as their surface ligands are described. These nanoparticles spontaneously form macroscopic assemblies at low temperature and relatively high salt concentrations, due to the cooperative formation of guanosine quartets and G-quadruplexes between the individual nanoparticles. Significantly, the solution behavior of these nanoparticles is highly controllable by adjusting through solution temperature, ionic strength and the sequence of G-rich oligonucleotide, and the aggregation process was found highly reversible. Since guanosine monophosphate is one of the essential building blocks for DNA, this work provides a deeper understanding of DNA modified nanostructured materials and DNA-nanoparticle probe design.
520 $a Finally, a novel approach of using fungi to template the assembly of pre-synthesized and oligonucleotide-functionalized nanoparticles into ordered structures is reported. Once assembled, secondary structure can be introduced into the living materials, either through hybridization events on the surfaces of the oligonucleotide-functionalized particles or by initiating further fungi growth followed by introduction to a second nanoscale particle building block. This approach allows one to dynamically control the nano-, micro-, and macroscopic architectures of the resulting materials by relying on the fungi as living templates and the nanoparticles as sequence-specific building blocks.
