Abstract

Photodynamic therapy (PDT) is an emergent technique used in clinical treatments for several pathologies, in which the photoactivation of photosensitizer molecule leads to cell death. Our project investigates the photodynamic effect of Protoporphyrin IX (PpIX), one of the currently most used photosensitizers, in prokaryotic cells, in order to explore its use in sterilization. Atomic Force Microscopy (AFM) and Wide Field Microscopy (WFM) were used to evaluate PDT effects on X.fastidiosa cells.
