Chapter 1 describes the design and synthesis of a two-state materials system based on an autocatalytic, positive feedback loop that amplifies a rare input into a massive output. Chapters 2 - 4 probe nanoparticle systems with shape or functional anisotropy. Chapter 2 details new approaches to add functionality to shape-anisotropic particles. Chapter 3 establishes NMR spectroscopy as a powerful tool for interpreting the ligand shell morphology, spatial arrangement, dynamics, and distinct chemical environments that are trademarks of shape- and functionally-anisotropic particles. Chapter 4 exploits the heterogeneous reactivity of shape-anisotropic particles to fabricate sophisticated, supramolecular building blocks that can form dynamic assemblies controlled by their association constants. Chapter 5 builds on the robust NMR techniques in the preceding chapters to analyze complex nano-bio interactions that are otherwise difficult to probe.
