Resumo
O interesse em materiais que apresentam propriedades microbicidas têm crescido, visto que tais produtos têm sido importantes em diversos cenários, incluindo contextos industriais, clínicos e agrícolas. O mesmo ocorre com a nanotecnologia, devido ao potencial de nanopartículas em diferentes contextos. Metais, como por exemplo o cobre, que apresentam propriedades microbicidas, podem agir tanto separadamente, quanto juntos, constituindo as denominadas ligas metálicas, contribuindo na contenção da propagação de doenças, inclusive infecciosas, tais como a COVID-19. A utilização de nanoligas metálicas compostas por nanopartículas metálicas com atividade antimicrobiana, pode contribuir para a redução da taxa de infecção por microrganismos patógenos presentes em superfícies e materiais de amplo uso em diferentes ambientes. O objetivo deste trabalho foi avaliar a atividade antimicrobiana de nanopartículas à base de cobre (Cu) e óxido de cobre (CuO) frente a diferentes patógenos, além de propor suas possíveis aplicações. Ensaios microbiológicos foram realizados com as nanopartículas sintetizadas. Os ensaios microbiológicos demonstraram resultados atraentes quanto ao potencial microbicida dos materiais avaliados, indicando inibição de crescimento microbiano, e confirmando seu possível uso como agente microbicida.
The interest in materials that exhibit microbicidal properties has grown, since these materials have been important in various scenarios, including in industrial, clinical and agricultural contexts. The same occurs with nanotechnology, due to the potential of nanoparticles in different contexts. Metals such as copper that have antimicrobial properties, can act both separately and together constituting the so-called metallic alloys, helping to contain the spread of diseases, including infectious ones, such as COVID-19. The use of metallic nanoalloys composed of metallic nanoparticles with microbicidal activity can contribute to reducing the rate of infection by pathogenic microorganisms present on wide use materials and surfaces in different environments. The aim of this work was to evaluate the antimicrobial activity of copper (Cu) and copper oxide (CuO)-based nanoparticles against different pathogens, in addition to proposing their possible applications. Microbiological tests were carried out with copper-based nanoparticles. The microbiological tests demonstrated attractive results regarding the microbicidal potential of the nanoparticles evaluated, indicating inhibition of microbial growth, and confirming their possible use as a microbicidal agent in nanoalloys.
