Electroanalytical Sensing with Polymeric Receptor-Doped Sensor Membranes
Selective electrodes for the detection of ions in liquids such as human body fluids or environmental waters are highly sensitive and selective analytical tools that offer a variety of advantages, such as simplicity of measurement, high analysis throughput, rapid detection, continuous on- line monitoring, and low cost of analysis. While such sensors are used in clinical laboratories for billions of measurements every year, applications in continuous health monitoring, the food industry, and environmental sciences still pose challenges. The Buhlmann group has contributed to the development of such sensors with new design principles and quantitative theory as well as the introduction of new materials to meet the needs of real life applications. This talk will address the long-term sensor stability of wearable and implantable sensors, challenges and opportunities of calibration-free measurements, miniaturization and low-cost design for point-of-care analysis, and—in view of long-term monitoring in the human body and the environment—robust design and resistance to chemical and biological fouling.
Philippe Buhlmann
Professor Philippe Buhlmann has been a member of the University of Minnesota Department of Chemistry since 2000. His group’s research is interested in the use of molecular recognition for chemical sensing. Their chemical sensor development focuses on new receptors that bind analytes of interest with high selectivity, novel strategies to obtain very low detection limits, and perfluoropolymers that permit long- term monitoring and eventually the implantation into the human body. Buhlmann’s research also pursues new ways to chemically modify metal and carbon nanotube tips, and use them in scanning tunneling microscopy for chemically selective imaging with molecular resolution.
Over the past two decades, his dedication to research and mentorship have earned the 3M/Alumni Professorship and the Distinguished University Teaching Professorship. Earlier this year, he received the American Chemical Society’s 2023 Minnesota Award “for being an international authority in the field of ion-selective electrodes and related research fields, for his outstanding work in volunteering for MN ACS, for being an outstanding research advisor, mentor, scholar and teacher AND having a positive impact on the lives of many graduate students in his own research group, in the Chemistry Department, and beyond.”
