Abstract
Functionalization of modern materials is one of the possibilities to make them better tailored for human needs. The paper describes a method of covering the titania nanotubes (TNTs) surfaces formed on Ti6Al4V (grade V) titanium alloy with four platinum(II) bimetallic complexes and cisplatin. The first step of the fabricated TNTs modification was their covering with (3-mercaptopropyl)triethoxysilane (MPTES) which plays a role of a bridge between the TNTs and platinum(II) coordination centres. The final application of platinum(II) dimethylformamide (DMF) solutions allowed to form a homogeneous layers of platinum(II) complexes bonded to the TNTs substrate by thiol sulphur atoms of MPTES without visible crystals of physically deposited complexes. The complexes were characterized with XRD, IR, Raman, 1H and 13C NMR spectroscopies, and thermal and elemental analyses. Characterization of titania substrates was done with IR, Raman, SEM, SEM/EDX, XRD, and XPS.
