Abstract
L'invention concerne des nanoparticules contenant des photosensibilisateurs liés par covalence qui remédient au problème de la libération prématurée et améliorent donc le résultat de la PDT. L'invention concerne des nanoparticules à base de silice qui contiennent au moins un photosensibilisateur lié par covalence. Le photosensibilisateur est de préférence constitué de composés à base de tétrapyrrole de types porphyrines, chlorines, bactériochlorines, benzochlorines, dérivés de benzoporphyrine, phéophorbides, notamment pyrophéophorbides, et phthalocyanines, naphthanocyanines avec et sans systèmes de cycles condensés et dérivés de tous les composés ci-dessus. La nanoparticule peut également comprendre des agents d'imagerie liés par covalence, par exemple radionucléides, agents d'imagerie par résonance magnétique (RM) et fluorescence. Les agents d'imagerie et les photosensibilisateurs peuvent se trouver à la périphérie (surface) des nanoparticules pour augmenter leur efficacité. Des nanoparticules spécifiques d'une cible peuvent être obtenues en incorporant des molécules de ciblage biologique, comme des anticorps spécifiques sur la surface, qui réagissent avec des ligands particuliers pour obtenir une spécificité de cible. Des agents de diagnostic peuvent être présents dans l'anticorps en plus d'agents d'imagerie et de photosensibilisateurs spécifiques d'une tumeur.
