Biosensors evoke images of tiny chips and wireless technology, but the next generation of biosensors may be: holograms costing only fractions of a cent, and the technology could usher in an era of "smart labels" that show when food is spoiled or when body glucose and alcohol levels are too high.Prototypes developed include contact lenses that monitor glucose levels, thin badges that detect alcohol levels, and sticks that can tell, instantly, if milk has spoiled or become contaminated. The technology promises to be quicker and cheaper than tests used today and can be deployed with minimal training.. A test showing that fuel has been contaminated with trace amounts of water reads "dry" or "wet." In a breath alcohol test intended for police offices, suspects breathe onto tiny cards that either show a green automobile or a red X, establishing whether a person is sober enough to drive.
