Smart labels help our food talk to us

Smart-cartons of milk; wine that tells you when it’s at the right temperature; and window panes that display the day’s weather are all closer to reality following newly revealed research at Trinity College.

The Science Foundation Ireland-funded Advanced Materials and BioEngineering Research (AMBER) Centre has announced that it has produced printed devices with 2-dimensional nanomaterials that “combine exciting electronic properties with the potential for low-cost production”.

The centre said that these “nanosheets” are flat nanoparticles that are a few nanometres thick but hundreds of nanometres wide.
