Abstract: Nanostructures underpin our efforts at exploring molecular-level phenomena and the physicochemical properties of the players. Our research builds from nanofabrication technique development to the design, fabrication, characterization, and application of nanoscale devices. A vital offshoot of this effort is the development of new experimental methods that fully leverage the unique capabilities of the tailored devices. We have a particular interest in approaches that bridge conventional and unconventional materials and processes, and that maximize—often by repurposing and augmenting—the performance capabilities of those materials. Top-down nanofabrication using free-standing silicon nitride thin films yields a nanofluidic device for straightforward transmission electron microscopy (TEM) on liquid samples. The same thin films can be bestowed, through bottom-up approaches, a
