Learning outcomes It is intended that the student learn the fundamentals about the design, construction, operation and analysis of results obtained with biosensors. Different types of biosensors are discussed both in terms of biological recognition elements used and transduction modes.
At the end of the curricular unit (UC) the student should be able to:
1. Describe the principles of operation and signal transduction in biosensors;
2. Decide for a given biosensor on the most suitable biological element for the analyte under study, as well as the way to immobilize it;
3. Plan, design, build and evaluate the functioning of biosensors;
4. Perform measurements with biosensors;
5. Obtain and analyze the parameters that characterize the functioning of a biosensor;
6. Solve problems related to measurement equipment associated with a biosensor;
7. Work as a team to solve theoretical and practical problems.

Teaching Methodologies and Assessment Criteria The teaching-learning activities are based on theoretical, theoretical-practical and laboratory classes, in which the objectives to be achieved (learning objectives) will be identified by topic. In theoretical classes, means of active learning are introduced, resorting to the use of mobile phones, specifically questionnaires are introduced with distractors that reflect common misconceptions of students. To encourage their participation, competitions are also held during these questionnaires and the results displayed in a histogram in order to alert students to their mistakes. Videos are also shown (always complemented with questions) that illustrate the construction and functioning of the different types of biosensors to be addressed in the UC.
Theoretical-practical and laboratory classes are focused on project-based learning. 4 mini-projects are carried out. In these, students are organized into groups of 2/3 students and given the problem to be solved.
Language Portuguese. Tutorial support is available in English.
