Paul Bohn's Biography



Paul Bohn, Arthur J. Schmitt Professor of Chemical and Biomolecular Engineering and Professor of Chemistry and Biochemistry, University of Notre Dame

Paul W. Bohn received the B.S. from the University of Notre Dame in 1977 and the Ph.D. from the University of Wisconsin-Madison in 1981, both in Chemistry. After two years at Bell Laboratories, he joined the faculty at the University of Illinois at Urbana-Champaign (UIUC). In 2006, he moved to the University of Notre Dame where he is currently the Arthur J. Schmitt Professor of Chemical and Biomolecular Engineering, Professor of Chemistry and Biochemistry, and Director of the Institute for Precision Health. He served as Editor for the Americas for the RSC journal Analyst 2007-09 and as Chair of the Editorial Board 2010-14. Prof. Bohn is currently co-editor of Annual Review of Analytical Chemistry. His research interests include: (a) integrated nanofluidic and microfluidic chemical measurement strategies for personal monitoring, (b) chemical and biochemical sensing in mass-limited samples, (c) biochemical imaging, and (d) molecular approaches to nanotechnology, areas in which he has over 290 publications and 10 patents.

Hydrophobic gating in biological transport proteins is regulated by stimulus-specific switching between filled and empty nanocavities, endowing them with selective mass transport capabilities. Inspired by these, solid-state nanochannels have been integrated into functional materials to realize electrochemical biosensors with integral mass transport control. Hierarchically organized structures are composed of polystyrene-b-poly(4-vinyl)pyridine (PS-b-P4VP) block copolymer on two-electrode nanopore electrode arrays (BCP@NEAs) housing target-specific enzymes. The BCP enables potential-responsive gating, making it possible to capture and confine analyte species in the attoliter-level NEA volume, enabling redox cycling and current amplification factors >100X. The enzyme-coupled sensing capabilities have been demonstrated with a variety of substrates, including cytokines (IL-6, TNF-alpha), metabolites from lipid nanoparticle degradation, and environmentally-relevant markers. Limits-of-detection <70 fM are obtained in favorable cases. The mass transport-controlled sensing platform described is relevant to next-generation point-of-care devices.
