Tagging pathogens with synthetic DNA 'barcodes'

e is spread on a sheet of absorbent paper and made visible to the naked eye. Or the color can be observed directly through a fluorescent light microscope, which is useful in situations where the geographic distribution of the target molecules is important, Luo said.

For convenience, a computer can convert the subtle differences in light intensity between, say 4G1R and 3G1R, into "pseudo colors," perhaps making one appear as orange and the other as pink, to make the difference clear to a human eye.

The researchers point out that the nanobarcode detection system does not require complex preparation of a sample and can be applied to living cells. The technology could be used in genomic research, clinical diagnosis, drug testing, environmental monitoring and monitoring for biological terrorism, they suggest.

Further details on "tree-shaped" DNA appear in a paper in Nature Materials (Vol. 3, Pg. 38-42, 2004).
