Nanoparticles represent a versatile set of building blocks for constructing functional materials with properties that can be exploited for both existing and emerging technologies.  Although many of these applications would significantly benefit from the organization of nanoparticles into higher order architectures, the precise placement and arrangement of nanoparticles over large areas of a surface remain a challenge.  Large area nanomanufacturing of these nanomaterials with high throughput and reproducibility is critical to the commercialization success of these technologies.  This seminar will begin with a discussion of the core-shell FMNPs that we have developed for self-assembled magnetic storage media.  While these particles are suitable for developing prototype magnetic media, we have also discovered that these well-defined particles can also be utilized as a model system for investigating solvent-driven directed self-assembly of nanomaterials on patterned substrates.  Thus, a general method for rapidly organizing nanoparticles on patterned surfaces will also be presented.
