Biosensors based on modified TiO2 nanoparticles
Valkovičová, Jiřina ; Adam, Vojtěch (referee) ; Hubálek, Jaromír (advisor)
The work is focused on quantum dots (QDs) array fabrication from titanium dioxide using template based non-lithographic method and their luminescence (fluorescence) properties study. The paper describes TiO2 QDs surface modification with gold using suitable template technique and subsequent functionalization of gold modified QDs surface via oligonucleotides. This functinalization step provides a suitable base for subsequent hybridization reaction with detected nucleic acid. The system of biosensor (TiO2 QDs modified with gold and biomolecules) is designed for rapid optical diagnosis of viral diseases.

Galvanic Deposition of Gold Nanorods via AAO Template for VOCs Sensing
Šetka, M.
The use of gold nanostructures for the creation of sensing devices for volatile organic compounds (VOCs) is particularly important because of their unique electronic, optical, and catalytic properties. In this paper, the synthesis of gold nanorods was described. The preparation of nanoporous alumina template was done via electrochemical anodization. The fabrication of gold nanorods was provided via electrochemical deposition into the nanoporous alumina template. Working conditions during the anodization had a significant influence on the pore diameter and thus on size of gold nanorods. The detailed topography of the nanostructured surfaces was characterized by scanning electron microscopy (SEM).
