Detection of microbial contaminants in food

Research has been carried out in order to exploit the aspect of immunological specificity coupled to acoustic based transducer technology for the detection of spoilage and/or pathogenic microorganisms in food.

The work has involved:
the nucleotide sequence determination of a ferric siderophore receptor protein from Pseudomonas strain M114, domain analysis of the receptor protein to identify surface exposed regions and to generate antibodies directed against such regions;
analysis of the adsorption of radiolabelled immunoglobulin G (IgG) to silver and lithium niobate surfaces;
fabrication, electrical characterization and analysis of the performance of surface acoustic wave (SAW) devices in liquid environments;
design and construction of SAW devices;
assessment of the specificity of developed antibodies.
