Sustainable materials for the design of forefront printed (bio)sensors applied in agrifood sector

The search for sustainability has now become a duty for all those entities, nations or people who intend to combat poverty in the world, safeguard the environment and bridge the gap of disparities that unfortunately still exist between underdeveloped countries and medium-high developed nations. The agrifood sector plays an important role in this vision, and the development of sustainable analytical devices at low cost and easy to use for everyone, suitable for being adopted by those countries whose technological development does not allow them to take up expensive and sophisticated laboratory techniques, may constitute a contribution towards achieving the objectives listed above. In this review we illustrate some examples of electrochemical devices realized utilizing sustainable materials, such as paper, as support for disposable and reagent-free (bio)sensors applied to the monitoring of food quality and safety. We also mention the first applications of new carbonaceous materials obtained from the recycling of agrifood waste products, which promise interesting features for electrochemical applications.
