CAMARGO-AMADO, R. J.. Photocatalytic Effect of TiO2-Au on cells of cervical cancer. Ing. compet. [online]. 2012, vol.14, n.2, pp.191-198. ISSN 0123-3033.

Photocatalysts have opened the possibilities to many applications in science and medicine. The TiO2 in presence of ultraviolet UV-A is opening up space in the future treatment of various cancers. In this work we determined the effect of the composite photocatalytic TiO2 and TiO2-Au on cells of cervical cancer (HeLa) and healthy cells of Chinese hamster ovary (CHO) cell lines. Was varied compound concentration, the exposure time to UV-A and the presence or absence of UV-A. Was measured cytotoxicity of the compounds on HeLa and CHO cells with Lactatedeshydrogenase test (LDH). The highest cytotoxicity in HeLa cells was 43.2 %, while the cytotoxicity in CHO cells in all cases was negative. The compounds causes no cytotoxic effect on CHO cell lines

Keywords : Cervical cancer; Photocatalysis; TiO₂-Au; TiO₂.
