The course of Environmental Bioanalytical Chemistry is about the basic principles of bioanalytical methods and their applications in environmental science. In the field of environmental health, pollutants, after entering living organisms, interact with various biological molecules and thus produce toxic effects. Therefore, as a fundamental tool for studying the structure and function of biomolecules, bioanalytical technologies are essential for the study of environmental issues. In this course, the most advanced modern bioanalytical technologies, including biosensors, biochips, lab-on-a-chip concepts, single-molecule DNA sequencing, computational toxicology, etc., will be introduced to the students with case studies to enable them to understand the basic principles of bioanalytical technologies and to develop theirability to apply the appropriate tool to solve problems in the environmental field.
