Molecular Layering Synthesis of TiO2 Nanolayer with Developed Roughness on Silicon as a Promising Basis for Biosensors

Abstract

Conditions for the synthesis of dispersion titanium dioxide with a developed roughness by molecular layering on the silicon surface were determined and structural characteristics of the resulting layer were studied. Electroactive surface area of the titanium dioxide nano-roughened films obtained by the proposed method is higher than those of the reference (smooth) titanium oxide film and the reference silicon electrode by factors 1.1 and 1.2, respectively.
