heal.abstract | The purpose of this research was to investigate the effectiveness of the free and encapsulated AlClPc into PLA nanoparticles in photodynamic therapy. Due to the hydrophobicity of the AlClPc molecule, its systemic administration as a photosensitizer is problematic. For this reason, an in vitro photodynamic study has been done in prostate LnCap cells, usisng free AlClPc and AlClPc encapsulated into polymeric nanoparticles (NPs) of polylactic acid (PLA) that were prepared. The NPs were prepared by the emulsification -evaporation of the solvent technique, with the following characteristics: (I) size of 300-400 nm, (ii) a negative zeta potential, (iii) PDI <0,3, (iv) encapsulation efficiency 28%. The characteristic photophysical parameters of free AlClPc and AlClPc in NPs were analyzed, such as absorption spectra and fluorescence, the photobleaching, the abillity of ROS generation and the toxicity of NPs and AlClPc were also analyzed. AlClPc loaded in polymeric nanoparticles and free AlClPc, exhibited the same phototoxicity. Phototoxicity is improved by increasing the concentration of the photosensitizer or the light dose. Also nanoparticles exhibited better carrying capacity of the photosensitizer into the cells and possible mitochondria targeting at the same incubation time . | en |
