Although thin films of LnPc 2 have been investigated by our group as the sensing material for voltammetric electrodes in a variety of applications (Rodríguez-Méndez et al, 2008b;Rodríguez-Méndez et al, 2009), their capabilities as electron mediators have not yet been analysed.…”

“…Electrodes chemically modified can be an advantage because the electrocatalytic activity of a variety of modifiers (carbon nanotubes, porphyrins, phthalocyanines, etc.) can reduce the oxidation potential while increasing the intensity of the electrochemical response [18][19][20][21][22].…”

Tyrosinase-based biosensors containing a phthalocyanine as electron mediator have been prepared by two different methods. In the first approach, the enzyme and the electron mediator have been immobilized in carbon paste electrodes. In the second method, they have been introduced in an arachidic acid Langmuir-Blodgett nanostructured film that provides a biomimetic environment. The sensing properties of non-nanostructured and nanostructured biosensors towards catechol, catechin and phenol have been analyzed and compared. The enzyme retains the biocatalytic properties in both matrixes. However, the nanostructured biomimetic films show higher values of maximum reaction rates and lowest apparent Michaelis-Menten constants. In both types of sensors, the sensitivity follows the decreasing order catechol > catechin > phenol. The detection limits observed are in the range of 1.8-5.4 μM for Langmuir-Blodgett biosensors and 8.19-8.57 μM for carbon paste biosensors. In summary, it has been demonstrated that the Langmuir-Blodgett films provide a biomimetic environment and nanostructured biosensors show better performances in terms of kinetic, detection limit and stability.

“…Adapted from data in [43] low-cost and miniaturized sensing units with good sensitivity and repeatability. The capability of discrimination demonstrated by PCA and the capability of prediction of fish freshness calculated by partial least squares-discriminant analysis (PLS-DA) were similar in both cases [46].…”

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.
