Development of colorimetric devices, obtained by functionalizing different solid substrates with dyes that change their color in the presence of a particular analyte or a class of contaminants. Chemometric multivariate analysis is applied for the data treatment. Several applications have been developed and are constantly evolving for monitoring the freshness of protein foods. Devices for the recognition of volatile analytes for environmental applications are under development.
