Biomimetic Nose by Microcrystals and Oriented Films of Luminescent Metal Organic Frameworks

ii The development of artificial noses are mainly for the quality control in food processing, detection and diagnosis in medicine and detection of drugs, explosives and dangerous or illegal substances. Artificial noses are keen by the food, pharmaceutical, TNT and beverage industry and any other trade in which monitoring for control quality of products is essential. We tried to mimic the working principles of a mammalian nose. The brain recognized the ―fingerprint ‖ an ensemble of signals (coming from all the glomeruli) and not a single response from one specific cell. Similarly, the artificial nose was made by an array of sensors instead of a single sensor, and the analysis of a composite fingerprint instead of separate individual signals. In this study, the metal organic frameworks displayed outstanding advantages of the capability of adsorption and guest-dependent luminescent property, thus exhibiting potential sensing application as the biomimetic nose. Normally, a
