Photodynamic diagnosis of parathyroid glands with nano-stealth aminolevulinic acid liposomes

Results and conclusion: Stealth liposomes were insignificantly higher in drug encapsulation%, in vitro drug release and zeta potential compared to conventional liposomes. Additionally, they needed less time for the start of the photosensitization and recorded the highest signal after spectrometry compared to the other two preparations. These data provide a new evidence of the potentiality of ALA-stealth Liposomes for identification of PTGs intraoperatively and could lead to propose a non-invasive procedure with reduced postoperative side effects.
