Their PDT effects were evaluated. Furthermore, nuclear imaging potential of 131I-labelled SubPc/SubPc-TiO2 were examined in mouse mammary carcinoma (EMT6) and cervix adenocarcinoma (HeLa) cell lines. The uptake results show that SubPc labelled with 131I radionuclide (131I-SubPc) in EMT6 and HeLa cell lines was found to be approximately the same as in the WI38 cell line. However, the uptake values of SubPc-TiO2 labelled with 131I (131I-SubPc-TiO2) in EMT6 and HeLa cell lines were determined to be two times higher than in the WI38 cell line. In other words, the target/non-target tissue ratio was identified as two in the EMT6 and HeLa cell lines. 131I-SubPc-TiO2 is promising for imaging or treatment of breast and cervix tumors. In vitro photodynamic therapy studies have shown that SubPc and SubPc-TiO2 are suitable agents for PDT. In addition, SubPc-TiO2 has higher phototoxicity than SubPc. As a future study, in vivo experiments will be held and performed in tumor-bearing nude mice. © 2019 World Scientific Publishing Company.eninfo:eu-repo/semantics/closedAccessnuclear imagingphotodynamic therapysubphthalocyaninetitanium nanoparticleArticle10.1142/S1088424619500639-2237-89089152-s2.0-85067170832Q3
