Artificial ‘nose’ can sniff out damaged fruit and spoiled meat

Although smell has historically played an important role in the fight against diseases such as the plague and tuberculosis, the human nose is generally not sensitive enough to be used as a reliable diagnostic tool. However, a new artificial “nose” inspired by our sense of smell could now make it possible to detect undiagnosed disease, hazardous gases, and food that is starting to spoil. And it is all made possible with technology that already exists. Although smell has historically played an important role in the fight against diseases such as the plague and tuberculosis, the human nose is generally not sensitive enough to be used as a reliable diagnostic tool.
