Resumo: During the last decades, researchers have been growing the interest in surface treatment with an antimicrobial agent. Silver nanoparticles (AgNPs) are widely used in biomedical fields due to their potent antimicrobial activity. So, in this study was investigated silver particles (isles) coated on titanium surface for dental and orthopedic application. Silver particles coating process on titanium surface were performed via sputtering that is a plasma-assisted deposition technique with and titanium without treatment was applied as comparing standard. Plasma treatment parameters were optimized so that the result was not a thin film of Ag but dispersed particles of Ag on the Ti-cp surface. The alloy surfaces were investigated using scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS). In order to investigate antibacterial potential Staphylococcus aureus and Escherichia coli have been used at Agar diffusion assay. The results were analyzed by analysis of variance (ANOVA) in order to verify significant difference antimicrobial activity between samples that have shown no difference between the surfaces studied treatments. For silver deposition scattered particles (isles) over titanium surface for a 10-minute treatment, EDS revealed by silver clusters that the particles were not properly scattered onto surface, hence, the low effectiveness in antibacterial activity.

Las nanopartículas de plata (AgNP) se usan ampliamente en campos biomédicos debido a su potente actividad antimicrobiana. Entonces, en este estudio se investigaron partículas de plata (islas) recubiertas en superficie de titanio para aplicaciones dentales y ortopédicas. El proceso de recubrimiento de partículas de plata en la superficie de titanio se realizó mediante pulverización catódica, que es una técnica de deposición asistida por plasma y se aplicó titanio sin tratamiento como estándar de comparación. Los parámetros de tratamiento con plasma se optimizaron para que el resultado no fuera una película delgada de Ag sino partículas dispersas de Ag en la superficie de Ti-cp. Las superficies de aleación se investigaron mediante microscopía electrónica de barrido (MEB) y espectroscopía de rayos X de dispersión de energía (EDS). Con el fin de investigar el potencial antibacteriano, se han utilizado Staphylococcus aureus y Escherichia coli en el ensayo de difusión en agar. Los resultados se analizaron mediante análisis de varianza (ANOVA) para verificar la diferencia significativa de la actividad antimicrobiana entre las muestras que no mostraron diferencias entre los tratamientos de las superficies estudiadas. Para las partículas de plata dispersamente depositadas (islas) sobre la superficie de titanio para un tratamiento de 10 minutos, EDS reveló al presentar grupos de plata que las partículas no se dispersaron adecuadamente en la superficie, por lo tanto, la baja efectividad en la actividad antibacteriana.Nas últimas décadas, os pesquisadores têm aumentado o interesse no tratamento de superfície com um agente antimicrobiano. Nanopartículas de prata (AgNPs) são amplamente utilizadas em campos biomédicos devido à sua potente atividade antimicrobiana. Assim, neste estudo foram investigadas partículas de prata (ilhas) revestidas na superfície de titânio para aplicação odontológica e ortopédica. O processo de revestimento das partículas de prata na superfície do titânio foi realizado por pulverização, que é uma técnica de deposição assistida por plasma e o titânio sem tratamento foi aplicado como padrão de comparação. Os parâmetros de tratamento com plasma foram otimizados para que o resultado não fosse um filme fino de Ag, mas partículas dispersas de Ag na superfície do Ti-cp. As superfícies das ligas foram investigadas por microscopia eletrônica de varredura (MEV) e espectroscopia de raios X dispersiva em energia (EDS). Para investigar o potencial antibacteriano Staphylococcus aureus e Escherichia coli foram utilizados no ensaio de difusão em ágar. Os resultados foram analisados por análise de variância (ANOVA), a fim de verificar diferenças significativas na atividade antimicrobiana entre amostras que não mostraram diferença entre as superfícies estudadas. Para partículas de prata dispersamente depositadas (ilhas) sobre a superfície de titânio para tratamento de 10 minutos, o EDS revelou, ao apresentar aglomerados de prata, que as partículas não foram adequadamente dispersas na superfície, logo a baixa efetividade na atividade antibacteriana.Research, Society and Development2020-03-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/266210.33448/rsd-v9i4.2662Research, Society and Development; Vol. 9 No. 4; e27942662Research, Society and Development; Vol. 9 Núm. 4; e27942662Research, Society and Development; v. 9 n. 4; e279426622525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/2662/2269Copyright (c) 2020 Lucas Victor Benjamim Vasconcelos, Patrícia Capellato, Cláudia Eliana Bruno Marino, Gilbert Silva, Rodrigo Perito Cardoso, Kayam Zardo Hamdar, Daniela Sachsinfo:eu-repo/semantics/openAccessCapellato, PatríciaMarino, Cláudia Eliana BrunoSilva, GilbertVasconcelos, Lucas Victor BenjamimCardoso, Rodrigo PeritoHamdar, KayamSachs, Daniela2020-08-20T18:07:16Zoai:ojs.pkp.sfu.ca:article/2662Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:27:09.978631Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
