Jonathan Claussen, PhD, Assistant Professor at Iowa State University
Dr. Claussen presented “How Nanotechnology Can Solve Some of Society’s Most Pressing Agricultural and Biomedical Challenges” on Thursday, March 21, 2019. Agricultural fertilizer run-off, food borne pathogens, spinal cord injuries, and late-stage cancer are agricultural and biomedical challenges that create high health and economic tolls throughout our society. The solutions to these issues are currently being addressed right here in Iowa at Prof. Jonathan Claussen’s ‘Nanoengineering Laboratory’ at Iowa State University. This presentation by Prof. Claussen focused on the science and technology behind developing efficient methods to produce sensors, energy harvesters, and biotechnology with nanomaterials for solving these important agricultural and biomedical challenges.
The presentation focused on large-area, solution-phase printing of nanomaterials that enable the production of low-cost, flexible and highly efficient electrical circuits. These graphene-based electrical circuits can then be used to monitor concentrations of fertilizer ions, foodborne pathogens, or cancer biomarkers much like someone with diabetes monitors his or her glucose levels. Use of nanomaterials allows for printable fabrication techniques to create higher quality sensors, allow for more flexible applications, and are cost effective to produce. The presentation concluded with thoughts on how this research can be transitioned into commercialized products.
