Original Abstract

This work focuses on developing TiO2 planar ordered nanostructures (quantum dots) for sensing of various biomolecules (DNA, proteins) in vitro, which may be of great importance for clinical diagnostics and in vivo imaging. This sensor array also called fluorescence array detector can provide various emitting QDs depending on wavelengths, and thus it can be used for in vitro large-field analysis, which means an easy detection of many different biomolecules at the same time. The new way of QDs synthesis employs the electrochemical deposition through high-ordered nanoporous alumina template, which belongs to low-cost and rapid technique for nanostructures preparation compared to traditionally used ones, photolithographic or epitaxial depositions. Self-organized array of titania QDs in anatase phase (confirmed by Raman spectroscopy) with diameter less than 10 nm (observed in SEM) were fabricated by combined anodization process of evaporated Al and sputtered Ti layers on silicon substrate. These QDs showed broad emission peak in visible range of fluorescence spectra after thermal treatment in vacuum at 400 degrees for 1 h.
