To distinguish between a wide range of volatile compounds and their possible mixtures, high-dimensional data represents the extreme variability of space chemical properties. That is why the olfactory system uses hundreds of receptors. Diverse chemical arrays solve both the third and fourth problems: stronger interactions lead to greater sensitivity (and with disposable arrays, "poisoning" arrays is no longer a problem), and diverse interactions Significantly increase the differentiation power of arrays (as a result of increasing array data dimensions). Here we look at colorimetric sensor arrays and their analysis, which overcomes many of the weaknesses of previous electronic nose methods. These arrays, from a variety of chemically responsive colors, create a hybrid pattern of color changes that report the local chemical environment. For example, they produce a unique molecular fingerprint for each given analyte or mixture of analytes. For colorimetric sensors, two structural features are necessary to design the molecular structure: functionality for chemical interaction with analytes and chromophore for coupling with this interaction.
