Learning objectives
- Chemistry
The student will have to acquire the capability to connect the chemical nomenclature to the corresponding formula and to describe the structure and function of macromolecules such as carbohydrate, proteins, lipids and nucleic acids present in the cell. He must recognize the functional groups responsible for the reactivity of the molecules. He must acquire an overview of the mechanisms that govern the transformation of the molecules and its correlation with the production and consumption of energy. He must understand and appreciate the connections between chemistry and biology.
The student must acquire the ability to select and apply the gained knowledge not only in theory but also while carrying out training activities.
- Applied Physics
The Applied Physics course has been designed to convey knowledge and understanding of basic physics principles, providing an introductory basis for other major degree fields including Chemistry, Biology, Physiology, Biochemistry, etc., that rely on the physical phenomenology on make frequent use of it.
The course will also provide the conceptual basis for understanding a number of major technologies that with increasing frequency are used in medicine, such as: centrifuges, endoscopes, microscopes, transducers for
ultrasound equipment, laser systems, radiology equipment and NMR, radiation detectors, etc. In this sense, the module also aims to develop the students' attitude towards independent study and continuing education on the application of physical techniques to diagnosis and therapy in medicine.

Teaching methods
Lectures will be held on-site in compliance with safety standards, provided that further instructions on the ongoing health emergency are not implemented. Supporting material will be available on the specific, student-reserved platform (Elly) and will include slide presentations, audio-video aids or video-recording of the lectures.
Assessment methods and criteria
- Chemistry
The assessment of the achievement of the objectives set by the Course includes a written test.
Overall, the test is intended to certify whether the student has achieved a good knowledge and understanding of the whole chemical principles that underlie life processes and if he is able to select and apply them to solve simple problems.
In case of the persistence of the health emergency, the exams will be conducted remotely, as follows: structured written test conducted remotely (by Teams or Elly).
- Applied Physics
The achievement of the course aims is proofed by a written examination. Using open-ended questions and the solution of problems about the contents of the course it will be determined whether the student has achieved the goal of knowledge and understanding of content about specific biomedical applications.
If due to the persistence of the health emergency it is necessary to adopt the remote modality for the exams, we will proceed with a
written test conducted remotely (via Teams and Elly) in the same way as the classroom test. The candidate will remain connected with microphone and video camera turned on and will carry out the test under the control of the commission.
Consultation of the didactic material will be allowed.
