Description
Photodynamic Therapy (PDT) is a technique clinically used in pathologies such as skin or
oesophagus cancer, where tumors are destroyed by intense light- induced tissue oxidation. The
method relies on the administration of a photosensitizer molecule that is suitable to induce the
formation of active species which are powerful oxidizing agent, able to cause necrosis or apoptosis
in cancer cells. The fundamental mechanisms by which the oxidation of biomolecules occurs are
complex and imply chemical, physical and biological phenomena. This lecture will be an
introduction to this complex world.
