Research Interests

The Bohn group uses the tools of molecular nanotechnology to define the state-of-the-art in chemical analysis of mass-limited samples (ranging from ~106 molecules down to a single molecule). Our research currently focuses on problems in three thematic areas: low-dimensional analytical electronics and photonics, analytical nanofluidics, and correlated imaging, and uses the tools of nanofabrication, high sensitivity molecular spectroscopy, and electrochemistry to achieve our research goals.
Analytical nanofluidics – research in this area concentrates on four major projects: (1) non-aqueous microchip electrophoresis (NAME) for lipid biomarker detection; (2) chemical reactions in confined/constrained environments; (3) design of extraordinarily efficient chemical reactors (NanoPERfECT); and (4) plasmonic and Fourier transform impedance sensing of toxins and pathogens.
Low-dimensional analytical electronics and photonics – research in this area exploits low-dimensional structures to perform chemical measurements and is focused on four major projects: (1) atom-scale junctions for chemical sensing; (2) single molecule spectroelectrochemistry; (3) electrochemistry in 1-D nanostructures; and (4) tightly coupled electrokinetics and electron transfer.
Correlated imaging – research in this area seeks to develop novel methods of heterocorrelated chemical imaging and is composed of two major projects focused on: (1) the molecular etiology of cancer, and (2) communication of microbial communities.
