“…An array of 5 graphite-epoxy voltammetric sensors made with different modifiers added to the bulk mixture were selected according with previous study in our laboratory with wines ( Figure 1) [5]. Four of them were modified by adding components as nanoparticles of copper, platinum or conducting polymer in powder like polyaniline and polypyrrole (Sigma-Aldrich, St. Louis, USA) -one component per sensor [22][23][24][25].…”

“…including mass, optic, electrical or electrochemical transduction (Baldwin, Bai, Plotto, & Dea, 2011;Haddi et al, 2014;Riul, Dantas, Miyazaki, & Oliveira, 2010;Rodríguez-M endez, Medina, De Saja, Apetrei, & Muñoz, 2012;Sghaier, Barhoumi, Maaref, Siadat, & JaffrezicRenault, 2009;Sliwinska, Wisniewska, Dymerski, Namiesnik, & Wardencki, 2014;Smyth & Cozzolino, 2013). Arrays of electrochemical sensors have been successfully used to discriminate between wines with different organoleptic characteristics Cet o, Apetrei, Del Valle, & Rodríguez-M endez, 2014;Cet o et al, 2012;Gay et al, 2010;Gil-S anchez et al, 2011;Guti errez, Moreno-Bar on, Pividori, Alegret, & Del Valle, 2010;Parra, Hernando, Rodríguez-M endez, & De Saja, 2004;Rodríguez-M endez et al, 2014;Zeravik, Hlavacek, Lacina, & Skl adal, 2009) or grapes of different qualities (Guti errez et al, 2011;Moreno i Codinachs et al, 2008). It has also been established that arrays combining sensors and biosensors can be advantageous, as they bring together both the benefits of classical arrays of electrochemical sensors (which provide global information about the sample) with the specificity of the enzymeesubstrate reaction typical of biosensors Moreno i Codinachs et al, 2008).…”

“…For two DWT-based feature extraction methods, we chose Daubechies 1 (Harr) wavelet as the wavelet basis due to its simplicity and wide application in DWT analysis. Considering high dimensionalities of raw responses and extracted features, we implement PCA transformation for the results of feature extraction methods mentioned above to visualize their distributions [31,32]. We used red markers to denote the beverages belonging to each liquor type: beer (block), spirit (asterisk), and red wine (pentagram), while the sample distributions of black tea, maofeng tea, pu'er tea, and oolong tea are shown in black color by a triangle, asterisk, block, and circle, respectively.…”
