A variety of configurations and formats have been devised to exploit the phenomenon of surface plasmon on metal dielectric interfaces for sensing a variety of significant analytes, such as pesticides and explosives, pathogens and toxins, and diseased tissue. Researchers continue to aim at detecting lower concentrations in smaller volumes of samples in real time. A new research field, called nanoplasmnonics, has emerged in this regard.read more

A Surface Plasmon Resonance Biosensor for Real-Time Immunologic Detection of Escherichia coli O157:H7
TL;DR: Testing of foods for the presence of pathogenic organisms requires methods different than those employed in the clinical laboratory, and a period of enrichment culturing of the sample in liquid growth medium is usually required to allow the organism to recover from injury and to allow for selective growth of low numbers of the target bacteria to detectable levels.
