Book excerpt: "DNA nanotechnology relies on the molecular recognition properties of DNA to produce complex architectures through self-assembly. DNA nanostructures allow scientists to organize functional materials with nanoscale precision, with applications spanning materials science, bioengineering, and physics. In addition to their remarkable performance as frameworks for other species, DNA constructs also possess intrinsic dynamic properties due to the non-covalent interactions that bring them together and show exceptional promise in the areas of controlled, personalized drug delivery and the development of biosensors.Although DNA nanostructures have become increasingly intricate and functional, the development of tools to study them has lagged. Historically, ensemble measurements have been primarily used to analyze the outputs of DNA nanotechnology, averaging the behaviour of billions of molecules within a sample to generate an output. This averaging means that the structure and performance of each individual construct is obscured, concealing malformed structures and masking properties associated with heterogeneity in size, length, and shape in self-assembled samples. For integration into engineered nanomaterials and biomedical devices, it is imperative that the DNA nanomaterials within a sample be structurally identical, with predictable and controllable behaviour. This goal requires the development of new analytical tools for the real-time observation of nanostructure assembly and actuation.This thesis describes the expansion of single-molecule fluorescence methodologies to probe the self-assembly pathways of DNA nanomaterials. These techniques monitor the self-assembly kinetics of surface-grafted DNA constructs, giving rise to a new generation of monodisperse, user-defined structures prepared using fully automated methods. The dynamic nature of these measurements also allows the single-molecule differentiation of the mechanisms of supramolecular polymerization. Exploring the fine-grained detail of self-assembly will enable the actualization of DNA nanostructures in custom delivery and sensing applications. In establishing new strategies to detect the assembly pathways of DNA architectures, this thesis provides a cohesive framework towards understanding hierarchical DNA assemblies at the single-molecule level"--
