    (2016) Tereshchenko, Alla V.; Smyntyna, Valentyn A.; Konup, Ihor P.; Geveliuk, S. A.; Starodub, M. F.; Конуп, Ігор Петрович; Конуп, Игорь Петрович; Терещенко, Алла Володимирівна; Терещенко, Алла Владимировна
    In this report an application of some metal oxide nanostructures as a biosensor platform for the detection of dangerous biological compounds (Bovine leucosis, Salmonella) have been discussed. The attention is paid to the TiO2 nanoparticles and ZnO nanorods deposited on the flat surface. The changes in photoluminescense signal from nanostructured surface were applied as biosensor response to detect the analytes. The detection range of TiO2 based biosensor for Bovine leucosis antibodies was in the range of 2–10 g/ml. The detection range of ZnO based biosensor for Salmonella antigens was 102–106 cells/ml. The obtained results provide a good basis for the use of optical properties of metal oxide based semiconductor nanostructures in biosensor technology.

    Optical Biosensors Based on ZnO Nanostructures: Advantages and Perspectives. A Review
    (2016-06) Tereshchenko, Alla V.; Bechelany, Mikhael; Viter, Roman; Khranovskyy, Volodymyr; Smyntyna, Valentyn A.; Starodub, M. F.; Yakimova, R.; Терещенко, Алла Владимировна; Терещенко, Алла Володимирівна
    This review article highlights the application of beneficial physico-chemical properties of ZnO nanostructures for the detection of wide range of biological compounds. As the medical diagnostics require accurate, fast and inexpensive biosensors, the advantages inherent optical methods of detection are considered. The crucial points of the immobilization process, responsible for biosensor performance (biomolecule adsorption, surface properties, surface defects role, surface functionalization etc.) along with the interaction mechanism between biomolecules and ZnO are disclosed. The latest achievements in surface Plasmon resonance (SPR), surface enhanced Raman spectroscopy (SERS) and photoluminescence based biosensors along with novel trends in the development of ZnO biosensor platform are presented.
