Design of chemical sensor arrays that can identify multiple analytesand complex mixtures has been attracting tremendous analysts’ interest. The pattern-based response obtained not from any single selective sensor but an assembly of cross-reactive sensors composes a unique fingerprint for each analyte. The excellent works of Anslyn Anzenbacher and Suslick have highlighted the recent shift in the application of chemical sensor arrays from single analytes to complex mixtures. Impressive examples include the identification of red wines black teas soft drinks toothpastes, beers and coffee grounds
