Summary: | The post synthetic assembly of nanowires into desired configurations presents a unique challenge. The inherent size of nanowires does not lend it self to a method or process capable of easily arranging or manipulating these materials. The recent understanding of how contact-line deposition, or the "coffee-ring effect", influences isotropic particles has lead to interest in investigating its influence over nanowires. Research has shown that nanowires can be aligned and selectively deposited at the edge of a drying droplet as a result of evaporation-induced capillary flow. From this basic understanding several methods have developed with the intent of producing a facile, robust, and scalable nanowire assembly process. This work provides insight into the coffee-ring effect and the mechanisms that draw from it to align, assemble, and pattern nanowire structures prior to introducing and providing the results of a new contact line deposition method. === A Thesis submitted to the Department of Industrial and Manufacturing Engineering in partial fulfillment of the requirements for the degree of Master of
