Special Issue Information
Dear Colleagues,
The concepts of electronic tongues (e-tongues) and electronic noses (e-noses) have developed rapidly in recent years due to their vast potential. They are based on electrochemical sensors combined with multivariate data analysis. The development of new analytical methods to characterize food is of vital importance for improving current quality and safety control systems. E-tongues and e-noses are holistic systems that provide global and qualitative information about samples. However, if the data matrix obtained by such multisensor systems is analyzed with adequate chemometric processing tools, descriptive or predictive information about specific parameters can be also extracted. Moreover, biosensors have been successfully implemented in these systems to develop bioelectronic devices. The electrochemical sensors used in these systems must incorporate appropriate electroactive and/or sensing materials that can interact with compounds of interest in the food industry. Some candidates for this task include conducting polymers, metal nanoparticles, metal oxide nanoparticles, porphyrins, phthalocyanines, and/or enzymes. In this context, nanotechnology can play an important role in manufacturing nanostructured sensors through various surface modification techniques.
This Special Issue focuses on recent research activities in the field of electronic tongues and noses for food analysis. Authors are encouraged to submit suitable articles/reviews addressing innovations in the field of electrochemical sensors/biosensors; novel electronic devices for food quality control; lab-on-chip devices; microsystems for food analysis; new electrocatalytic materials for sensing units; advanced fabrication processes based on nanotechnology; and in situ systems for food quality control, among other applications in foodstuff analysis.
