The use of biosensor and microarray techniques in the rapid detection and identification of salmonellae

The ever-present need for rapid and sensitive assay methods to detect foodborne pathogens, particularly the salmonellae, has led to increased incorporation of biosensor technology into microarray and other platforms. The use of mimetics and aptamers has been added to these procedures. Nanoparticles, particularly incorporating fluorophores and quantum dots into various procedures, have decreased the size of instrumentation while increasing automation, sensitivity, and rapidity of results. This article will deal mainly with assays involving the salmonellae.
