Objectives

The Fundamentals of Biophysics course provides students with basic biophysics knowledge aligned with the latest scientific and technological developments in modern medicine. The goal is to understand the fundamental principles of biophysics that underlie biomedical phenomena and new spectroscopic methodologies, while promoting an interdisciplinary perspective that integrates physical laws and concepts as applied to biology and medicine.
The course is organized into the following modules:
Part I (6 hours) – Fundamentals of physics: electric and magnetic fields, electromagnetic waves, geometric optics. Molecular interactions: covalent bonding, electrostatic, and van der Waals interactions.
Part II (6 hours) – Thermodynamics applied to biological systems: internal energy, free energy, reaction kinetics, energy associated with electromagnetic radiation.
Part III (12 hours) – Biological polymers: structure and function of nucleic acids (DNA, RNA) and proteins; protein folding mechanisms.
Part IV (6 hours) – Energy in living systems: energy metabolism, photosynthesis, ATP production. Study of biomembranes, nerve signal transmission, memory function, biomechanics, and hearing.
Part V (10 hours) – Techniques and methodologies: introduction to X-ray diffraction, electron microscopy, optical microscopy, and UV-Vis spectroscopy.
Part VI (8 hours) – Nanomaterials for drug delivery: plasmonic and organic nanoparticles, nanoparticle functionalization, photosensitive nanoparticles, and controlled drug release mechanisms.

Lessons mode

The course occurs with lectures where students have required continuous interaction by favoring questions on the topics discussed during the lesson.

Frequency

Attendance is not mandatory, although it is strongly suggested. However, students with an attendance >68% can present a research project instead of a standard written exam. The formal written exam consists in solving ten problems related to the topics of the course.


Exam mode

To be admitted to the oral exam, students must pass the written exam with a score of 18/30

Written exam: Research project (if the attendance is >68%)

Written exam: 10 problems (if the attendance is < 68%)

Example exam questions

Describe a helpful spectroscopic technique to characterize a biological polymer.
