Israeli Researchers Develop 'Bionic Nose' To Sniff Out Signs of Cancer
Both cancer cells and the chemicals used to make bombs can foil detection because they appear in trace amounts too small for conventional detection techniques.
But now, scientists at Tel Aviv University have engineered a molecule that can magnify weak traces of "hidden" molecules into something we can detect and see.
Using molecular techniques in nanotechnology, Professor Doron Shabat of TAU's Raymond and Beverly Sackler School of Chemistry has engineered new molecules that have the power to identify targets - such as biomarkers in cancer, materials in explosives, or pollutants in water - even when present in miniscule amounts.
Professor Shabat's invention, like a bionic nose, can "sniff out" these trace molecules and amplify them tenfold, making them noticeable for doctors and crimefighters.
Shabat, a bioorganic chemist, plans to develop the technology so that it amplifies signals millions and billions times stronger than they are.
"We are developing a molecular system that amplifies certain events," said Shabat. "That way, we'll be able to respond faster to medical, security and environmental threats. In effect, our device can amplify just about any chemical system that has a certain kind of reactivity," he added.
