Scientists announce molecule-based ID tags
Scientists in the U.K. have manipulated molecules that are capable of basic logic operations and could become an alternative to RFID tags. Complex procedures have been put together to create a technique called molecular computational identification (MCID). Such molecules can be manipulated using a certain mix of chemicals and give of light as a result. Such light-based output makes the molecules the equivalent to RFID tags. The difference is that these tags are, of course, very small.
