Elective
3rd Cycle Studies
Recommended Prerequisites
General Chemistry; Physics I and II, Analytical Chemistry; Organic Chemistry.
Teaching Methods
Oral presentation of theoretical concepts in powerpoint. Classes for implementing and/or exemplification of techniques and analyzes, tutorials, and even occasional guest speakers. Laboratory classes for running assemblies of biomedical instrumentation.
Monitoring the literature research work to explore a topic as exhaustive and thoroughly as possible, leading to a written report and an oral presentation. Promote critical and collaborative participation of students in a process of active learning, based on case studies, in business information, or studies still at the research stage.
Learning Outcomes
In this course students get insight about the need to develop equipment for detection, analysis and diagnosis, for specific compounds identification, in important and diversified areas of application, such as health, environment, food industry and pharmaceutical industry. They realize the interdisciplinary of several knowledge to achieve that goal mainly chemistry, physics, electronics and different branches of engineering. They get skills in the understanding and proposal of alternatives, methodologies and strategies to conciliate the bio recognition with the translation of signals, for application to new detection equipment and optimization of the existing ones. Students get knowledge about the main transducers, used for physiological and environmental applications, contacting directly some of them in laboratory. Students also get knowledge on methods of detection, measurement and registration of biomedical signals. They know the main biomedical applications already in practice.
