“…Esse interesse não é apenas acadêmico, mas fortemente perseguido por setores que empregam alta tecnologia, como a indústria automobilística, 1 farmacêutica, 2 eletrônica, 3 aeroespacial, 4 de embalagens, 5 entre outras. 6,7 Um dos melhores exemplos do sinergismo entre descobertas científicas e desenvolvimento tecnológico empregando materiais nanoestruturados foi visto com a indústria de fabricação de equipamentos eletrônicos. De fato, a descoberta de novos materiais semicondutores permitiu a produção de chips cada vez menores, criando dispositivos com alto nível de miniaturização.…”

The growing interest of researchers in the development of nanomaterials can be measured by the large number of articles and patents that have been published in recent years. In particular, inorganic, organic or even hybrid nanoparticles of different sizes and shapes are already synthesized in a very controlled manner and without very elaborated experimental conditions. However, despite the advances, much work remains to be done on the use of nanoparticles as building blocks for the generation of new nanostructured materials and devices. Actual manipulation of nanoparticles for the construction of a particular device has many limits and usually requires high cost and high technology equipment. However, a promising strategy that can lead to the formation of nanostructured arrangements in a very controlled manner is based on nanoparticle self-assembly processes. Directed particle self-assembly can be described as a planned, controlled and organized aggregation of the particles to obtain a specific particles arrangement or device. Self-assembling material not only serves to generate a structure itself, but also to achieve unique chemical and physical properties in the material that arise only due to the arrangement and interactions between the nanoparticulates. Due to the importance of this subject for the development of nanotechnology products, this article shows, through a broad and generalized approach, some of the most common methods found in the specialized literature about self-assembling of metallic nanoparticles. O crescente interesse de pesquisadores no desenvolvimento de nanomateriais pode ser medido pelo grande número de artigos e patentes que vêm sendo publicados nos últimos anos. Particularmente, nanopartículas inorgânicas, orgânicas ou mesmo híbridas, das mais variadas formas e tamanhos, já são sintetizadas de maneira bastante controlada e sem condições experimentais muito elaboradas. Entretanto, apesar dos avanços, ainda há muito trabalho por ser realizado quanto ao emprego de nanopartículas como blocos de construção para a geração de novos materiais e dispositivos nanoestruturados. A real manipulação de nanopartículas para a construção de um determinado dispositivo apresenta muitos limites e geralmente requer equipamentos de elevado custo e alta tecnologia. Contudo, uma estratégia promissora que pode levar à formação de arranjos nanoestruturados de maneira bastante controlada baseia-se em processos de automontagem de nanopartículas. A automontagem planejada de partículas pode ser descrita com uma agregação planificada, controlada e organizada das mesmas para a obtenção de um arranjo ou dispositivo. O material obtido por automontagem não serve apenas para a geração de uma estrutura em si, mas também para alcançar propriedades químicas e físicas singulares no material que se manifestam apenas devido ao arranjo e a interação entre seus componentes nanoparticulados. Devido à importância desse tema para o desenvolvimento de produtos nanotecnológicos, este artigo de revisão mostra, através de uma abordagem ...

Background: Foods that promote health benefits are being increasingly used. Innovative techniques, such as nanotechnology, have been used to improve functional properties, sensory characteristics, or the conservation of foods. Objective: The objective of this study was to identify the technological domain of patents for tomato products with or without nanotechnology and elucidate the technological advances associated with the recent use of tomatoes as a natural food dye in the food industry by exploring patent documents. Methods and Results: The search was conducted using the Espacenet and INPI databases. There was an increase in patent document applications employing nanotechnology in 2013, with a peak between 2017 and 2018. China is the lead country in the number of patent applications. In Brazil, the patent applications are variable, and the food industry is most involved in studies on tomatoes as a natural food dye. Most patent deposits using nanotechnology were from companies, and the main sources of the patent application were the food and pharmaceutical industries. Conclusion: There is an increasing trend for the use of tomatoes as natural food dyes, produced with or without nanotechnology, and number of patents filed yearly. New technologies are being developed in several application areas.
