An artificial nose system is able to recognise fatty acids that are associated with diseases
A South Korean research team has designed an artificial olfactory system capable of distinguishing short-chain fatty acids with 90 % reliability. These molecules serve as diagnostic biomarkers for diseases such as stomach cancer and halitosis, according to the authors, whose research is published in Science Advances. The system - consisting of human olfactory receptors, artificial synapses and an artificial neural network - is able to distinguish combinations of molecules, compared to current techniques that detect single molecules and single compounds.
