Tematika

Objectives and scope: Chemical sensors are important tools for everyday use. Using them concentration of different species can be given – real time- in complex matrices, such as blood, air or wastewaters. Students taking the course will learn the different kind of sensors. We demonstrate their structures, working principles and the selective recognition mechanisms. Depending on the field of application, the advantages and disadvantages of their use will be also discussed.  Sensors used in medicine, medical diagnostics and process control will be also discussed in details.
