Resumo: Titanium, when kept at ambient atmosphere and room temperature, generates a thin and adherent oxide layer (TiO2) which promotes corrosion restance. Due to this characteristic, the anodizing of titanium has been studied for biomedical applications, but despite excellent biocompatibility, titanium prostheses can generate implant-associated infections. The literature describes the incorporation of silver nanofillers (AgNPs) on the titanium surface, increasing the material's antimicrobial activity and, consequently, reducing the occurrence of infections. Thus, the objective of this work was to identify the most suitable process for incorporation of silver nanofillers on the anodized titanium surface. In this sense, titanium samples were (i) anodized in aqueous citric acid containing silver nitrate (AgNO3), (ii) anodized in aqueous citric acid and subsequently immersed in an aqueous solution of Psidium guajava extract + AgNO3 and (iii) anodized in H2SO4 + H2O2 followed by sealing process conducted in solution containing Psidium guajava extract + AgNO3. Scanning Electron Microscopy (SEM) and Energy Dispersive Spectroscopy (EDS) analysis were performed to verify the efficiency of incorporation of the nanofillers by each method. The results showed to be possible incorporate AgNPs over titanium oxide through the process (i) anodization in citric acid + AgNO3 and (iii) anodization in H2SO4 + H2O2 and sealing in solution containing plant extract + AgNO3. Furthermore, potentiodynamic polarization and cytotoxicity trials were performed on samples from process (iii) and revealed that the incorporation of AgNP's improves the corrosion resistance and favors the antimicrobial effect of the sample’s surfaces.

Debido a esta característica, el anodizado del titanio ha sido estudiado para aplicaciones biomédicas. A pesar de tener una excelente biocompatibilidad, las prótesis de titanio pueden generar infecciones asociadas a los implantes. Los estudios muestran que al combinar nanorrellenos de plata (AgNP) con titanio, se amplifica la actividad antimicrobiana del material, lo que reduce la tasa de infecciones. El objetivo de este trabajo fue identificar el proceso más adecuado para la incorporación de nanorrellenos de plata en titanio anodizado. Para ello, las muestras de titanio fueron (i) anodizadas en ácido cítrico que contenía nitrato de plata (AgNO3), (ii) anodizadas en ácido cítrico y posteriormente sumergidas en una solución de extracto vegetal + AgNO3 y (iii) anodizadas en H2SO4 + H2O2 y selladas en solución que contiene extracto vegetal + AgNO3. Se realizaron análisis morfológicos por Microscopía Electrónica de Barrido (SEM) y análisis químicos semicuantitativos por Espectroscopía de Dispersión de Energía (EDS) para verificar la eficiencia de incorporación de los nanorrellenos de cada método. Los resultados mostraron que es posible incorporar AgNPs al óxido de titanio a través del proceso (i) anodización en ácido cítrico + AgNO3 y (iii) anodización en H2SO4 + H2O2 y sellado en solución que contiene extracto vegetal + AgNO3. Además, las pruebas de polarización potenciodinámica y citotoxicidad se realizaron solo en muestras del proceso (iii) y demostraron que la incorporación de plata mejora el desempeño anticorrosivo del titanio y favorece el efecto antimicrobiano de la superficie para las bacterias.O titânio quando mantido em temperatura e atmosfera ambiente, produz uma fina e aderente camada de óxido (TiO2) tornando resistente à corrosão. Por essa característica, a anodização do titânio vem sendo estudada para aplicações biomédicas. Apesar de possuírem excelente biocompatibilidade, as próteses de titânio podem gerar infecções associadas ao implante. Estudos mostram que aliando nanocargas de prata (AgNPs) ao titânio, a atividade antimicrobiana do material é ampliada, o que reduz a taxa de infecções. O objetivo do trabalho foi identificar o processo mais adequado para incorporação de nanocargas de prata em titânio anodizado. Para tanto, amostras de titânio foram (i) anodizadas em ácido cítrico contendo nitrato de prata (AgNO3), (ii) anodizadas em ácido cítrico e posteriormente imersas em solução de extrato vegetal + AgNO3 e (iii) anodizadas em H2SO4 + H2O2 e seladas em solução contendo extrato vegetal + AgNO3. Análises morfológicas por Microscopia Eletrônica de Varredura (MEV) e análises químicas semiquantitativas por Espectroscopia De Energia Dispersiva (EDS) foram realizadas para verificar a eficácia de incorporação das nanocargas de cada método. Os resultados mostraram que é possível incorporar AgNPs ao óxido de titânio por meio do processo (i) anodização em ácido cítrico + AgNO3 e (iii) anodização em H2SO4 + H2O2 e selagem em solução contendo extrato vegetal + AgNO3. Além disso, testes de polarização potenciodinâmica e de citotoxicidade foram realizados somente nas amostras do processo (iii) e mostraram que a incorporação de prata melhora o desempenho anticorrosivo do titânio e favorece o efeito antimicrobiano da superfície em bactérias.Research, Society and Development2022-05-18info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2969010.33448/rsd-v11i7.29690Research, Society and Development; Vol. 11 No. 7; e13711729690Research, Society and Development; Vol. 11 Núm. 7; e13711729690Research, Society and Development; v. 11 n. 7; e137117296902525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/29690/25712Copyright (c) 2022 Mariane Fernandes; Sandra Raquel Kunst; Fernando Dal Pont Morisso; Lauren Arrussul Carús; Ana Luiza Ziulkoski; Cláudia Trindade Oliveirahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessFernandes, MarianeKunst, Sandra RaquelMorisso, Fernando Dal Pont Carús, Lauren Arrussul Ziulkoski, Ana LuizaOliveira, Cláudia Trindade 2022-06-06T15:12:05Zoai:ojs.pkp.sfu.ca:article/29690Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:46:42.059684Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
