Artificial noses are an attempt to create a synthetic system that can replicate the sense of smell. Practical applications of artificial noses include drug detection, bomb detection and possibly even disease detection. Although no artificial noses have yet been produced, research developments have moved the artificial nose closer to reality.Breitbart: MIT scientists move closer to 'artificial noses' (September 29, 2008)
