Our research has focused on imaging, manipulation, and spectroscopy at the nanoscale including the investigation of single molecule electronic and mechanical devices, and the development of a new imaging technique based on the mathematics of compressive sensing. To build and understand the mechanics of nanoscale motion and manipulation in molecular systems, we have used scanning tunneling microscopy (STM) to probe a family of molecules based around the concept of the Nanocar. I will highlight our recent work with various molecular wheels including fullerenes, carboranes, and ruthenium compounds. In addition to single molecule mechanics, we have employed STM to study polydiacetylene and polythiophene nanowires as candidates for molecular electronics.  Lastly, we have built an imager by coupling an optical modulator, a single detector, and the mathematics of compressive sensing. Benefits of our scheme include more sensitive and lower cost imaging beyond the visible spectrum as well as the implementation of a compressive confocal microscopy system.
