摘要：
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 mu g/ml. The detection range of ZnO based biosensor for Salmonella antigens was 10(2)-10(6) cells/ml. The obtained results provide a good basis for the use of optical properties of metal oxide based semiconductor nanostructures in biosensor technology.
