Abstract:
Human’s olfactory system has a large number of receptors that respond only to a limited number of molecules. Since human noses are subject to fatigue, inconsistency and lack the sensitivity to low-concentration molecules, scientists have developed the Electronic nose (E-nose). E-nose is a device that identifies the specific components of volatiles and analyzes the chemical makeup to identify them. Regarding the applications of this device, they include, but not limited to, detection of odors specific to diseases for medical diagnosis and are used for the detection of gas leaks for environmental protection. An E-nose consists of both, a mechanism for chemical detection through an array of electronic sensors and mechanism for pattern recognition like that of the neural network. As for chemical detection and relating to the previous work of our fellow colleagues and major development of the E-nose by scientists at Tufts University, our E-nose developed here consists of a Biosensor, which is a protein extracted from animals and a labeling component that is a chemical dye that is suitable compatible to the protein used. As for the electronic part of the prototype that is responsible for the detection of color change of the dye during the interaction with the odors, it is made up of an application programmed for this specific purpose that ensures proper detection of RGB (red, green and blue) value color change. Several trials were, and will be, further performed to validate the interaction between Biosensors and odor samples, in both liquid and solid phases.
