Modification of Mechanical and Functional Properties of Titania Nanotubes Using [Pt ₂ (6NNqui)Cl ₄ ] Complex Bonded Covalently via Bridging Ligand

] (PtQ6). The paper presents a modification of the Ti6Al4V alloy with titania nanotubes and the studied complex, using the bridging ligand (3-mercaptopropyl)triethoxysilane (MPTES). Moreover, a kinetic study on chloride substitution in the studied bimetallic cisplatin analogue (PtQ6) by L-cysteine, an amino acid that is a part of GSH and metallothioneins, is also presented. It is a good way to get locally active implants in the targeted anticancer therapy. The produced material is characterized with spectral and microscopic methods, including XPS (X-ray photoelectron spectroscopy). The mechanism of the substrate modification with platinum(II) complex is based on the substitution process. The nanomechanical properties of the modified and functionalized substrate are also tested in the indentation tests.
