Title: Study of modified solid surfaces by nanostructured CdSe in SiOxthin films
Keywords: biomineralization, laser-liquid-solid interaction, SiOx:CdSe

Abstract: The study of biomineralization is inspiring new approach to the controlled fabrication of synthetic “biomimetic” materials such as nanostructured semiconductors [1, 2]. To prepare model surfaces on titanium substrates, two groups of samples: (i) SiOx:CdSe multilayers (MLs) and (ii) CdSe nanometer-sized crystals embedded in SiOx matrix, called composite films (CFs), have been produced applying two regimes of well established physical vapour deposition at room temperature. Fourier Transform Infrared Spectroscopy (FTIR), Infrared Microscopy (IRM), Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray Spectroscopy (EDX) studies have been carried out. The ability of SiOx:CdSe MLs to induce crystallization in simulated body fluid (SBF) was tested. To enhance the process of crystal growth, laser-liquid-solid interaction (LLSI) was induced by pulsed laser irradiation. It is shown that the nanofa-bricated SiOx:CdSe layers might be exploited as model of biomineralization.
