Resumo: In the last decades, there has been an increase in interest in studies in the field of nanotechnology. These are due to the several advantages and applications that nanomaterials have. Along with advances in research involving nanotechnology, there is a concern with the control of bacteria, fungi, and viruses harmful to human health. A very clear and current example is the Pandemic (COVID-19) that the world is experiencing, which highlights the importance of controlling microorganisms in the atmosphere, water, and soils. Among the several materials that have the antimicrobial capacity, are silver and titanium dioxide. In this context, this work aimed to synthesize and characterize Ag/TiO2 nanocomposites by physical-chemical techniques and evaluate them against their antimicrobial power against E.coli microorganisms. S. aureus and C.albicans. Silver nanoparticles were dispersed over a matrix of titanium dioxide, which showed antimicrobial power between 62 and 71%, demonstrating to be a material with great potential to be used in water and air purifying products.

Juntamente com o avanço nas pesquisas envolvendo a nanotecnologia, está a preocupação com o controle de bactérias, fungos e vírus danosos à saúde humana. Um exemplo bastante claro e atual é a Pandemia (COVID-19) que o mundo está vivenciando, a qual ressalta a importância do controle de microorganismos existentes na atmosfera, água e solos. Dentre os inúmeros materiais que apresentam capacidade antimicrobiana, estão a prata e o dióxido de titânio. Nesse contexto, este trabalho teve como proposta sintetizar e caracterizar nanocompósitos de Ag/TiO2 por técnicas físico-químicas e avaliá-los em relação ao poder antimicrobiano frente aos microrganismos E.coli. S. aureus e C.albicans. Formaram-se nanopartículas de prata dispersas sobre uma matriz de dióxido de titânio, os quais apresentaram poder antimicrobiano entre 62 e 71% demonstrando ser um material com um grande potencial para ser utilizado em produtos purificadores de água e/ou ar.Universidade Federal de Viçosa - UFV2020-12-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/jcec/article/view/1160910.18540/jcecvl6iss5pp0682-0687The Journal of Engineering and Exact Sciences; Vol. 6 No. 5 (2020); 0682-0687The Journal of Engineering and Exact Sciences; Vol. 6 Núm. 5 (2020); 0682-0687The Journal of Engineering and Exact Sciences; v. 6 n. 5 (2020); 0682-06872527-1075reponame:Revista de Engenharia Química e Químicainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/jcec/article/view/11609/6401Copyright (c) 2020 The Journal of Engineering and Exact Scienceshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSousa, Maria Elisa Berriel de Remiro, Paula de Freitas Rosa Bernardo, AndreAguiar, Mônica Lopes2021-05-31T12:54:03Zoai:ojs.periodicos.ufv.br:article/11609Revistahttp://www.seer.ufv.br/seer/rbeq2/index.php/req2/indexONGhttps://periodicos.ufv.br/jcec/oaijcec.journal@ufv.br||req2@ufv.br2446-94162446-9416opendoar:2021-05-31T12:54:03Revista de Engenharia Química e Química - Universidade Federal de Viçosa (UFV)false
