“…They rely on the concept of global selectivity, according to which the measurements yield a ''finger print'' of the liquid or vapor under study. Several kinds of sensing elements and detection methods have been studied for e-noses and mainly e-tongues [45,51,[57][58][59][60][61][62], which allow applicability in fields as food [57,[62][63][64][65][66], wines [67], water [68] and pharmaceutical analysis [66]. The importance of the e-tongues and e-noses to biosensing stems from the possible extension through the incorporation of sensing units capable of molecular recognition [69][70][71][72].…”

An overview is provided of the various methods for analyzing biosensing data, with emphasis on information visualization approaches such as multidimensional projection techniques. Emphasis is placed on the importance of data analysis methods, with a description of traditional techniques, including the advantages and limitations of linear and non-linear methods to generate layouts that emphasize similarity/dissimilarity relationships among data instances. Particularly important are recent methods that allow processing high-dimensional data, thus taking full advantage of the capabilities of modern equipment. In this area, now referred to as e-science, the choice of appropriate data analysis methods is crucial to enhance the sensitivity and selectivity of sensors and biosensors. Two types of systems deserving attention in this context are electronic noses and electronic tongues, which are made of sensor arrays whose electrical or electrochemical responses are combined to provide “finger print” information for aromas and tastes. Examples will also be given of unprecedented detection of tropical diseases, made possible with the use of multidimensional projection techniques. Furthermore, ways of using these techniques along with other information visualization methods to optimize biosensors will be discussed.

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).…”

a b s t r a c tDisposable screen-printed sensors have been modified with enzymes and used to form a bioelectronic tongue dedicated to the discrimination between different grape varieties. The multisensory system combined serigraphied electrodes modified with carbon, platinum, gold, graphene, Prussian blue and nickel oxide nanoparticles (M-SPE) covered with glucose oxidase (M-GOX-SPE) or tyrosinase (M-Tyr-SPE).The M-GOX-SPE and M-Tyr-SPE sensors produced a variety of responses due to the different behavior of the electron mediators of the six screen-printed materials used for the electro-catalysis of the glucose and phenols by means of glucose oxidase and tyrosinase.This variety of responses, together with the capability of the sensors to detect glucose or phenols, allowed the bioelectronic tongue developed here to discriminate between the juices obtained from different varieties of grape.Partial least-squares (PLS-1) multivariate calibration of electrochemical data has been successfully applied to the simultaneous determination of glucose and polyphenols in musts.The discrimination capability shown by this array of cheap and single-use sensors was similar to that found in other complex bioelectronic tongues. The lower price, ease of use and portability of the modified screen-printed electrode system makes the bioelectronic tongue developed here an alternative tool that can be used in situ in the vineyard block.

“…These systems usually display 49 comparative/qualitative rather than quantitative information. Several research groups have developed 50 gas multisensor systems to determine the aroma of wine using electronic noses based on metal oxides, 51 such as SnO 2 Following our interest in the design of electronic tongues and noses [19] we report on the use 67 of a combined system for the analysis of the spoilage of wine when in contact with air. The system 68 consists of a potentiometric electronic tongue and a humid electronic nose.…”

ElsevierGil Sánchez, L.; Soto Camino, J.; Martínez Mañez, R.; García Breijo, E.; Ibáñez Civera, FJ.; Llobet Valero, E. (2011). A novel humid electronic nose combined with an electronic tongue for assessing deterioration of wine. Sensors and Actuators A: Physical. 171 (2) Abstract: We report herein the use of a combined system for the analysis of the spoilage of wine 16 when in contact with air. The system consists of a potentiometric electronic tongue and a humid 17 electronic nose. The potentiometric electronic tongue was built with thick-film serigraphic techniques 18 using commercially available resistances and conductors for hybrid electronic circuits; i.e. Ag, Au, 19 Cu, Ru, AgCl, and C. The humid electronic nose was designed in order to detect vapours that emanate 20 from the wine and are apprehended by a moist environment. The humid nose was constructed using a 21 piece of thin cloth sewn, damped with distilled water, forming five hollows of the right size to 22 introduce the electrodes. In this particular case four electrodes were used for the humid electronic 23 nose: a glass electrode, aluminium (Al), graphite and platinum (Pt) wires and an Ag-AgCl reference 24 electrode. The humid electronic nose together with the potentiometric electronic tongue were used for 25 the evaluation of the evolution in the course of time of wine samples. Additionally to the analysis 26 performed by the tongue and nose, the spoilage of the wines was followed via a simple determination 27 of the titratable (total) acidity. 28
