Bacteria Bearing Messages

Chemical Communications: Method permits encoding, decoding text messages with the use of living organisms
Department: Science & Technology
Keywords: steganography, bacteria

Aiming to enhance the interface between chemistry, biology, and information technology, a research team has developed a technique to encode messages in patterns of bacteria and reveal them through fluorescence.

“We think our technique can potentially be used for easy-to-read biological barcoding, as a deterrent to counterfeiting, or, of course, for secret communications,” says postdoc Manuel A. Palacios of Tufts University, first author of a paper describing the approach (Proc. Natl. Acad. Sci. USA, . . .
