SUMMARY:Electrochemical Ion Sensors: From the State-of-the-Art to Current 
 Challenges and Opportunities - Philippe Buhlmann\, 3M Alumni Professor of 
 Chemistry and Distinguished Teaching

DESCRIPTION:Selective electrodes for the detection of ions in liquids such
  as human body fluids or environmental waters are highly sensitive and sel
 ective analytical tools that offer a variety of advantages\, such as simpl
 icity of measurement\, high analysis throughput\, rapid detection\, contin
 uous on-line monitoring\, and low cost of analysis. While such sensors are
  used in clinical laboratories for billions of measurements every year\, a
 pplications in biomedical sciences\, the food industry\, and environmental
  monitoring have been hindered by sensor fouling and the frequent need for
  recalibration. This talk will first give an overview of the underlying pr
 inciples\, capabilities\, and limitations of ion-selective electrodes. It 
 will then turn to the challenges and opportunities that motivate ongoing r
 esearch\, which include (1) long-term sensor stability\, (2) calibration-f
 ree measurements\, (3) miniaturization and low-cost design for point-of-ca
 re analysis\, and—in view of long-term monitoring in the human body and 
 the environment—(4) robust design and resistance to chemical and biologi
 cal fouling.
