Resumo: | The COVID-19 pandemic, caused by the SARS-COV-2 virus, highlighted the need to develop safe and economically viable methods for carrying out disinfections on a commercial and domestic scale. Coronaviruses are more susceptible to UV-C radiation than fungi and bacteria and several studies related to the efficiency of UVC against the virus that causes COVID-19 have already been carried out using substitute microorganisms. Thus, this study sought to develop a device accessible to lay users for use in materials that cannot be subjected to conventional methods of eliminating microorganisms (chemical or thermal disinfection). This research proposed the production and validation of a portable UV-C emitting device for the disinfection of substrates susceptible to contamination by bacteria, fungi and pathogenic viruses. The device was developed from materials accessible to most companies and the population. Then, the device's efficiency was validated by exposing microbial cultures (Gram positive, negative bacteria and yeast) at different time intervals. The device was developed entirely from low-cost and accessible materials. All tested microorganisms (Candida albicans, Staphylococcus aureus and Escherichia coli) were removed from the culture medium in less than 20 min. exposure. The device developed in this study can be built by most companies and the population. The device proved to be effective in reducing the risk of contagion from different pathogenic microorganisms, suggesting its effectiveness against SARS-COV-2 that causes the COVID-19 pandemic. |

Los coronavirus son más susceptibles a la radiación UV-C que los hongos y las bacterias y ya se han realizado varios estudios relacionados con la eficiencia de los UVC frente al virus causante del COVID-19 utilizando microorganismos sustitutos. Así, este estudio buscó desarrollar un dispositivo accesible a usuarios no profesionales para su uso en materiales que no pueden ser sometidos a métodos convencionales de eliminación de microorganismos (desinfección química o térmica). Esta investigación propuso la producción y validación de un dispositivo emisor de radiación UV-C portátil para la desinfección de sustratos susceptibles de contaminación por bacterias, hongos y virus patógenos. El dispositivo se desarrolló a partir de materiales accesibles para la mayoría de las empresas y la población. Luego, se validó la eficiencia del dispositivo exponiendo cultivos microbianos (bacterias Gram positivas, negativas y levaduras) a diferentes intervalos de tiempo. El dispositivo fue desarrollado completamente a partir de materiales accesibles y de bajo costo. Todos los microorganismos analizados (Candida albicans, Staphylococcus aureus y Escherichia coli) se eliminaron del medio de cultivo en menos de 20 min. exposición. El dispositivo desarrollado en este estudio puede ser construido por la mayoría de las empresas y la población. El dispositivo demostró ser efectivo para reducir el riesgo de contagio de diferentes microrganismos patógenos, lo que sugiere su efectividad contra el SARS-COV-2 que causa la pandemia de COVID-19.A Pandemia COVID-19, causada pelo vírus SARS-COV-2, evidenciou a necessidade de desenvolvimento de métodos seguros e economicamente viáveis para a realização de desinfecções em escala comercial e doméstica. Os coronavírus são mais suscetíveis à radiação UV-C do que fungos e bactérias e diversos estudos relacionados à eficiência da UVC contra o vírus causador da COVID-19 já foram realizados utilizando micro-organismos substitutos. Desta forma, este estudo buscou o desenvolvimento de um dispositivo acessível a usuários leigos para utilização em materiais que não podem ser submetidos a métodos convencionais de eliminação de micro-organismos (desinfecção química ou térmica). Esta pesquisa propôs a produção e validação de um dispositivo emissor de radiação UV-C portátil para a desinfeção de substratos suscetíveis a contaminação por bactérias, fungos e vírus patogênicos. O dispositivo foi desenvolvido a partir de materiais acessíveis a grande parte das empresas e população. Em seguida foi realizada a validação da eficiência do dispositivo através da exposição de culturas microbianas (bactéria Gram positiva, negativa e levedura) em diferentes intervalos de tempo. O dispositivo foi desenvolvido plenamente a partir de materiais de baixo custo e acessíveis. Todos os micro-organismos testados (Candida albicans, Staphylococcus aureus e Escherichia coli) foram eliminados do meio de cultura com menos de 20 min. de exposição. O dispositivo desenvolvido neste estudo pode ser construído por boa parte das empresas e população. O dispositivo se mostrou eficaz para reduzir o risco de contágio de diferentes micro-organismos patogênicos, sugerindo sua efetividade contra SARS- COV-2 causador da pandemia COVID-19.Research, Society and Development2021-05-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1581710.33448/rsd-v10i6.15817Research, Society and Development; Vol. 10 No. 6; e31310615817Research, Society and Development; Vol. 10 Núm. 6; e31310615817Research, Society and Development; v. 10 n. 6; e313106158172525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/15817/14122Copyright (c) 2021 Alexsandro Silvestre da Rocha; Cláudia Adriana da Silva; Regina Lélis de Souza; Nilo Maurício Sotomayor Choque; Denisia Brito Soares; Eskálath Morganna Silva Ferreira; Mirelle Ribeiro Araújo; Juliana Fonseca Moreira da Silva; Raphael Sanzio Pimentahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessRocha, Alexsandro Silvestre da Silva, Cláudia Adriana da Souza, Regina Lélis de Choque, Nilo Maurício Sotomayor Soares, Denisia Brito Ferreira, Eskálath Morganna Silva Araújo, Mirelle Ribeiro Silva, Juliana Fonseca Moreira da Pimenta, Raphael Sanzio 2021-06-10T22:51:46Zoai:ojs.pkp.sfu.ca:article/15817Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:36:33.666405Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
