Fabrication and nanoscale organization of metal nanostructures is critical for applications including biosensing, biocatalysis, plasmonics, and energy harvesting and generation. While exquisite metal nanostructures can now be fabricated using a variety of methods, the challenge of controlling the spatial organization of such nanostructures is still being addressed. Recently, we have developed several approaches to create metal nanostructure platforms with both precise nanoscale arrangement and size/shape of the constituent components. We have used both particle lithography and scanning probe-based approaches to create a variety of precisely tunable metal nanostructures. We have also developed fabrication methods using salt-based resist layers that allow flexibility in the substrate for fabrication. Recent advances in the development of these methods as well as the potential applications, particularly in hybrid biomaterials, will be discussed.
