Abstract excerpt
Photoprotective potential and biological consequences (mutagenic potential) of octyl-dimethyl-PABA (ODP), titanium dioxide (TiO2 ), and montmorillonite (MMT) upon ultraviolet B (UVB) irradiation, alone and in different associations [physical mixtures (PMs)], were evaluated using a Saccharomyces cerevisiae ogg1 mutant (deficient) strain. In addition, we developed and characterized a delaminated TiO2-pillared MMT,...
