Hours of instruction:

Weekly: four hours of lectures + two hours of exercises + three hours of labwork (4+2+3)

Goals:

The aim of this course is to introduce students to the possibilities of practical use of electrochemistry in various fields of research. The course is divided into thematic areas and allows students to gain insight into the potential use of modern electrochemical methods in clarifying the results of their research. A separate section will relate to specific interactions in living systems and the environment as well as the development of sensors and biosensors to monitor them. In addition, students will be introduced to the latest third generation of biosensors: modes of synthesis of mediators (organic compounds and new materials) and recombination and adaptation of enzymes required for their development and construction. At the end of the course students will be introduced to the possibilities of combining electrochemical methods for different techniques in order to obtain better results and to explain specific phenomena.

Outcome:

Upon completion of this course, students will be able to independently and team prepare experiments and select electrochemical methods, as well as successfully combine these methods with other experimental techniques to complement their further research or find answers and explanations for particular parts of their research.
