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.

A highly sensitive, label-free immunosensing platform based on interdigitated electrode arrays (IDEAs) has been developed for the detection of IL-6, a critical cytokine biomarker for inflammation and trauma. The IL-6 IDEA sensor exhibits a LOD in PBS that is comparable to other label-free sensors and ELISA-based electrochemical immunosensors, and it achieves linear ranges at IL-6 concentrations across 4 orders of magnitude for all fluids. Thus, the IL-6 IDEA sensor is an excellent candidate for clinical application as a POC tool, given its simple assembly, ease of operation, straightforward analysis, and good sensitivity for IL-6 in physiological fluids. Furthermore, preliminary experiments on non-optimized structures show that operation in generator-collector redox cycling mode can produce significant amplification factors. The performance of the IL-6 IDEA sensor was also explored in both CSF and serum. The IDEA sensor is less sensitive to IL-6 in CSF and serum than in in PBS, which is expected due to the presence of interferents, such as cellular debris, proteins, lipids, etc. Although LODs in CSF and serum were higher, the IL-6 IDEA electrochemical immunosensor can reliably detect IL-6 across 4 orders of magnitude at clinically relevant concentrations in CSF and serum. CSF is the preferred physiological fluid for biomarker detection due to its exceptionally low concentration of non-target interferents relative to blood plasma or serum.
