Aditive manufacturing promoting human health: development of sensors, biosensors and active/smart food packaging

Abstract

The present proposal for cooperation between groups from São Paulo and Rio Grande do Sul envisages the development of different advanced materials, nano and micro-structured that have antimicrobial properties, materials that have active substances in their constitution or smart materials, that is, that can react to external stimuli. These materials will be applied in the preparation of devices for food packaging, such as monoliths or labels using 3D technology for their preparation. These devices should interact with food in order to protect them from attacks by microorganisms causing deterioration and/or controlled release of substances such as drugs or antioxidants. In addition, these materials should respond to stimuli such as radiation, heat and pH, quickly and irreversibly. Therefore, such devices should protect food from deterioration by increasing shelf life, as well as indicate if storage and transport have occurred under appropriate conditions. The advancement of these innovative technologies to prepare devices to be applied in the areas of active packaging, smart packaging and electrochemical sensors, provides a response to the growing demands of modern society on human health, food and the environment. The proposal involves the training of qualified human resources that are essential for the development and constant absorption of new technologies. (AU)
