This thesis aims to investigate the design of different delivery systems for the effective transport of photosensitizers towards a variety of biological targets and their potential applications in photodynamic therapy. The introduction of complexes endowed with targeting capabilities is crucial to effectively direct the cytotoxic activity of singlet oxygen towards the desired systems, such as bacterial or cancer cells. Within this work, proteins have been chosen as molecular scaffolds to be combined with different photosensitizers, improving the bioavailability of the latter ones by facilitating their solubility in aqueous solutions. The systems have been studies by the means of fluorescence microscopy, fluorescence correlation spectroscopy and cell viability.
Il lavoro presentato in questa tesi è rivolto allo sviluppo di differenti sistemi di trasporto di fotosensibilizzatori, con l’obiettivo di indirizzare tali molecole a target biologici ben precisi dimostrandone le potenzialità per applicazioni di terapia fotodinamica. L’introduzione di complessi multifunzionali dotati di capacità di targeting è un aspetto cruciale per generare una azione citotossica mirata ed efficace. In questo progetto, diverse proteine sono state selezionate come carrier molecolari e le loro proprietà sono state testate e studiate utilizzando un ventaglio di tecniche, tra cui la microscopia a fluorescenza, fluorescence correlation spectroscopy e saggi di vitalità cellulare.

Abstract
This thesis aims to investigate the design of different delivery systems for the effective transport of photosensitizers towards a variety of biological targets and their potential applications in photodynamic therapy. The introduction of complexes endowed with targeting capabilities is crucial to effectively direct the cytotoxic activity of singlet oxygen towards the desired systems, such as bacterial or cancer cells. Within this work, proteins have been chosen as molecular scaffolds to be combined with different photosensitizers, improving the bioavailability of the latter ones by facilitating their solubility in aqueous solutions. The systems have been studies by the means of fluorescence microscopy, fluorescence correlation spectroscopy and cell viability.File | Dimensione | Formato | |
