The barcodes have been primarily used to assure brand and authenticity in pharmaceuticals, but applications could be forthcoming in tracing food batches. Combined with pathogen sensors, the barcodes that must be read by modified microscopes could trace sources of outbreak. There are antibacterial surfaces for the machines involved in food processing or production. With the conventional methods of detection it takes hours to days. With molecular electronic based methods, biosensors, e-nose, microarrays, nanobiosensors (based on microfluidic, nanomaterials, DNA, etc.) it takes seconds to minutes. A biosensor developed by an Agricultural Research Service scientist, Athens, uses fluorescent dye particles attached to bacteria antibodies. If Salmonella bacteria are present in the food being tested, the nanoculturing results with these two examples of instantaneous sensors, sized dye particles become visible. No need to send out to the lab and wait days for results.
