A crescente necessidade de produção agrícola e a tentativa de atenuar os impactos negativos do uso intensivo de pesticidas, são desafios atuais para a segurança alimentar e dos alimentos, levando à procura de soluções tecnológicas mais sustentáveis. Os compostos convencionais apresentarem um papel fundamental na proteção das culturas e no aumento da produtividade, mas a sua utilização excessiva associa-se a contaminação ambiental, à presença de resíduos nos alimentos e ao desenvolvimento de resistências por parte de pragas e agentes patogénicos. A nanotecnologia surgiu como área com elevado potencial, com novas abordagens para melhorar a produção agrícola, diminuir a contaminação ambiental e aumentar a segurança dos alimentos. Neste contexto, pretende-se compreender de que forma esta tecnologia pode contribuir para a promoção da salubridade e da segurança alimentar, explorando-se as suas principais aplicações na agricultura e na sinalização de resíduos de pesticidas, bem como uma análise dos benefícios e dos limites associados à sua utilização. Serão descritos os desafios científicos, regulamentares e industriais que restringem a implementação desta nova tecnologia. O presente trabalho consiste numa revisão narrativa sobre o papel da nanotecnologia na melhoria da segurança alimentar e dos alimentos, com particular ênfase na sua aplicação no controlo e na monitorização de pesticidas e uso em fertilizantes. Identificando-se o potencial desta tecnologia na promoção de sistemas agroalimentares mais eficientes, seguros e sustentáveis, provando-se, simultaneamente, a importância de uma investigação contínua e do desenvolvimento de estratégias regulamentares adequadas que assegurem uma integração segura, responsável e eficaz da nanotecnologia no setor agroalimentar.
The growing need for agricultural production and the attempt to mitigate the negative impacts of intensive pesticide use are current challenges for food security and food safety, leading to a search for more sustainable technological solutions. Conventional compounds play a key role in crop protection and increasing productivity, but their excessive use is associated with environmental contamination, the presence of residues in food, and the development of resistance by pests and pathogens. Nanotechnology has emerged as a field with high potential, offering new approaches to improve agricultural production, reduce environmental contamination and enhance food safety. In this context, the aim is to understand how this technology can contribute to promoting food safety and security, exploring its main applications in agriculture and in the detection of pesticide residues, as well as analyzing the benefits and limitations associated with its use. The scientific, regulatory and industrial challenges that restrict the implementation of this new technology will be described. This study consists of a narrative review of the role of nanotechnology in improving food safety and food security, with particular emphasis on its application in the control and monitoring of pesticides and its use in fertilizers. Identifying the potential of this technology to promote more efficient, safe and sustainable agri-food systems, whilst demonstrating the importance of ongoing research and the development of appropriate regulatory strategies to ensure the safe, responsible and effective integration of nanotechnology into the agri-food sector.
