Layer-by-layer growth of titanate nanotubes on glass substrates was achieved by alternate layer deposition using an aqueous solution of colloidal titanate nanotubes and that of a polycation. Even a single layer thin film of titanate nanotube shows high photoinduced hydrophilicity.

Surface properties of Ti implants (especially surface hydrophilicity) influence biological responses at the interface between the bone tissue and the implant. However, only a little research reported the effect of surface hydrophilicity on osteoconductivity by in vivo test. We have investigated the surface characteristics and osteoconductivity of titanium implant produced by hydrothermal treatm...

OBJECTIVE Aseptic loosening of artificial knee joints induced by wear particles from a tibial polyethylene (PE) insert is a serious problem limiting their longevity. This study investigated the effects of grafting with our original biocompatible phospholipid polymer 2-methacryloyloxyethyl phosphorylcholine (MPC) on the insert surface. METHODS The hydrophilicity of the PE surface was determine...

Molecular shape, flexibility, and surface hydrophilicity are thought to influence the ability of nanoparticles to cross biological barriers during drug delivery. In this study, coarse-grained (CG) molecular dynamics (MD) simulations were used to study these properties of a polymer-drug construct in potential clinical development: poly(γ-glutamyl-glutamate)-paclitaxel-poly(ethylene glycol) nonpe...

Photoisomerization of spiropyrans has been the subject of many interesting studies in a wide number of fields, such as sensors for cations, sensors of pH, switchable surfaces, lasing effect, among many others. This molecule can be photoisomerized upon UV irradiation, giving rise to the zwitterionic merocyanine (MC) form, which dramatically changes its hydrophilicity and photophysical properties...

Self-assembled monolayers presenting imidazolium ions at the tail ends (SAMIMs) having different counteranions have been prepared on Au, and the measurement of water contact angles of the surfaces proved to be an extremely valuable simple technique for quantifying the effects of counteranions on hydrophilicity and hydrophobicity of SAMIMs, which will be extrapolated to the water miscibility of ...

Poor solvation of alkylthiols in a water-rich interfacial environment is shown to induce a dispersion of energetically-distinct states above a critical value of the hydrocarbon chain length, which depends on the hydrophilicity of the terminal group. Switching between single and dispersed states can be achieved by an adequate choice of the solvent composition.

Comparison between two amino-acid-sequences was quantified by matrices. The hydrophilicity of each amino acid was used as a parameter to characterize the sequence and its functional aspect in a water environment. The eigenvalues calculated in the linear transformation give an image of a biochemical conversion between two amino-acid-sequences.
