Is the food on the shelf really that what is written on the label? Its DNA would give it away, but the DNA barcoding technology, which can be used for this purpose, is labor-intensive. Now, in the journal Angewandte Chemie, Italian scientists have introduced a simplified assay coined NanoTracer. Combining DNA barcoding with nanotechnology, it requires neither expensive tools nor extremely skilled personnel, but just the naked eye to identify a color change.
