This work shows that ZrO, used as a modifier of TiO, can be highly effective as a co-catalyst in the photoelectrocatalytic degradation of dibutyl phthalate (DBP). The monoclinic phase of ZrO was easily obtained by chemical deposition on TiO nanotubes (E ~3.06 eV), increasing the occurrence of hydroxyl groups and acidity on the surface of the material, as observed by electrophoretic mobility measurements.

- An in situ evaluation of the interaction between double-stranded DNA (dsDNA) and methotrexate (MTX) was conducted using voltammetry and characterized by atomic force microscopy (AFM) on a highly oriented pyrolytic graphite (HOPG) surface.
- The experiments revealed that MTX modifies the dsDNA structure over time, causing changes to the self-assembled DNA network and resulting in a more compact and thicker lattice formation.
- The intercalation of MTX between the DNA base pairs leads to increased oxidation peaks for purines, indicating unwinding of the dsDNA, with additional investigations using various electrochemical biosensors to analyze this interaction.
