Teaching

Welcome to Biosensors
(CHE 598/494; CME 598/494)

Time and location
Tuesday/ Thursday, 3:40-4.55pm; rm. PS H433

Instructor
Dr. Joseph Wang

Textbook
“Analytical Electrochemistry” (Wiley-2000; required)

Course Objective
To cover the fundamentals of electron-transfer processes, electrochemical and optical methods for studying electrode reactions, modern instrumentation, electrode materials (including modified and microelectrodes), and a wide range of practical applications ranging from modern power sources to electroanalysis and sensors.

Electrochemistry is concerned with the interplay between electricity and chemistry. The field of electrochemistry covers a huge array of practical devices (e.g., fuel cells, microsensors and batteries) and phenomena (e.g., corrosion, electrolysis and electroplating) and thus has a very important role in industry.
