“…Per example, in the paper by Crew et al [69], the cross response of six genetically modified AChEs (B03, B04, B65, B131, B394 and B421) was evaluated against six organophosphate pesticides. Figure 24 shows pictorially the different patterns of inhibition presented by each AChE enzyme evaluated, clearly displaying the different patterns by each pesticide and announcing that the resolution of pesticide mixtures is possible.…”

This chapter presents recent advances concerning work with electronic tongues that employ electrochemical biosensors, that is, bioelectronic tongues. (Bio)electronic tongues represent a new methodological use of (bio)sensors; they start by the use of biosensor arrays and assume the coupling of the obtained complex response with advanced chemometric data treatment; the goal is improving performance of existing sensors. Most of the bioelectronic tongues reported employ enzyme biosensors, essentially based on potentiometric or voltammetric/ amperometric transduction. This report is organized considering the different forms to incorporate biosensors, i.e. considering the number of biosensors in the array, the number of different enzymes used, if the determination is aimed to substrates or inhibitors, etc. Significant applications in real problem-solving, mainly in the food and clinical or environmental fields, are commented.

“…Como consequência, têm mostrado alta versatilidade de aplicações, tanto na forma de eletrodo convencional, quanto na forma de eletrodo modificado. [21][22][23][24][25][26][27][28][29][30][31][32][33] Ademais, dependendo da aplicação, esses eletrodos podem ser empregados muitas vezes, barateando ainda mais o custo das determinações analíticas.…”

“…A rapid, reliable, economical and portable analytical system will be of great benefit in the detection and prevention of OPs contamination. A biosensor array based on six acetylcholinesterase enzymes coupled with a novel automated instrument incorporating a neural network program has been reported by Hart et al [44] . The biosensor array and the instrument is illustrated in Figure 12.…”
