Holst Centre and imec have demonstrated a single-chip electrochemical sensor for ethylene monitoring with a detection limit of 200-300ppb (parts per billion). Imec and Holst Centre’s solution enables small-size and low-cost ethylene detection systems applicable in the fruit distribution and retail sector. Ethylene is a gaseous plant hormone, produced by fruit, and responsible for the ripening of fruit. It is also sprayed in high concentrations (~1,000 ppm) in the warehouse, to force fruit to ...
