“…Values are also reported after 1 and 2 steps of Ar etching (60 s per step). In the case of the stainless steel substrates modified with the initiator 1 (S i ), P 2s (191 eV), P 2p (132 eV) [45][46][47] and Br 3d (72 eV) lines [48,49] are also clearly observed, indicating that the corresponding molecules of 11-(2-bromoisobutyrate)-undecyl-1-phosphonic acid (1) are present on the surface of the substrates. The percentages of the elements detected at the surface of S i are listed in Table 2.…”

“…The O1s peak at 530.1 eV is from vanadium oxide and the peak at 531.9 eV originates from the -OH species [12,22,23]. For hydrogenated VO 2 , the -OH peak is much stronger than V-O peak, indicating the formation of -OH bonds [22,23] The evolution of electronic structures can be inferred from measuring optical band gap.…”

We report modulation of a reversible phase transition in VO 2 films by hydrogen doping. Metallic and insulating phases are successively observed at room temperature as the doping concentration increases. The polarized charges induced by doped hydrogens gradually occupy V3d-O2p hybridized orbitals and consequently modulate the filling of the VO 2 crystal conduction band-edge states, which eventually become saturated and therefore evolve into new valence band-edge states. A clear linear relationship between H-concentration and V3d orbital occupancy were found.These results suggest the exceptional sensitivity of VO 2 electronic properties to electron concentration and orbital occupancy, providing key information for the phase transition mechanism.

“…Furthermore, they suggested a strong bidentate binding mode, bridging between two Ti atoms, though they performed no stability tests with the adsorbed molecules. Philippin et al (2003) compared the formation of monolayers of alkyl phosphonic acid with that of alkyl trichlorosilanes, finding that the latter form better ordered monolayers according to electrochemical impedance spectroscopy results. Gao et al (1996) investigated alkyl phosphonic acids bound to anatase, ZrO 2 or Al 2 O 3 with solid-state nuclear magnetic resonance and found only weak interaction between Ti and P-O owing to not completely deprotonated OH-groups.…”

Surface functionalization with bioactive molecules (BAMs) on a nanometre scale is a main field in current biomaterial research. The immobilization of a vast number of substances and molecules, ranging from inorganic calcium phosphate phases up to peptides and proteins, has been investigated throughout recent decades. However, in vitro and in vivo results are heterogeneous. This may be at least partially attributed to the limits of the applied immobilization methods. Therefore, this paper highlights, in the first part, advantages and limits of the currently applied methods for the biological nano-functionalization of titanium-based biomaterial surfaces. The second part describes a new immobilization system recently developed in our groups. It uses the nanomechanical fixation of at least partially single-stranded nucleic acids (NAs) into an anodic titanium oxide layer as an immobilization principle and their hybridization ability for the functionalization of the surface with BAMs conjugated to the respective complementary NA strands.
