Abstract
The development of self-disinfectant devices is highly needed to prevent and control infections, mainly caused by virus. In the past years, coronaviruses have been a threat to humanity, causing severe epidemics of respiratory infections such as severe acute respiratory syndrome (SARS), in 2003, and Middle East respiratory syndrome (MERS) in 2012, and presently the SARS-CoV2 is causing the COVID-19 pandemic. Previous studies have demonstrated that surface contamination play a significant role in the spreading of viruses. These studies demonstrated that the production of highly reactive species by copper alloys contributes to rapid elimination of viruses. Nanostructured materials such as semiconductors TiO2, Co3O4 CuO, NiO, and TiO2, and silver nanoparticles can decrease the virus viability on the surfaces when associated with polymers and textiles, especially in conditions of light exposure. In addition, graphene oxide is rising as a promising material for inactivation of viruses due to its capacity of destroying the viral envelope and capsid. The virucidal property of these materials can be enhanced by increasing their functionalization with photosensitizers. The present mini-review brings subsidies for the development of new advanced self-disinfectant materials that can be used in the manufacture of gloves, masks, and a variety of other devices.
Highlights
Basic aspects about viral infection and structure are important to develop nanostructured materials for rapid elimination of viral particles that contaminate surfaces.The disease COVID-19 New zoonotic respiratory viruses have emerged in humans in recent years
The results demonstrated that enveloped viruses were less resistant than the naked viruses
In addition to the development of anti-viral medicines and vaccines, the combat of viral infections should include the production of self-disinfecting materials
Summary
Basic aspects about viral infection and structure are important to develop nanostructured materials for rapid elimination of viral particles that contaminate surfaces.The disease COVID-19 New zoonotic respiratory viruses have emerged in humans in recent years. In 2003, in Guangdong Province, China, a highly pathogenic coronavirus caused severe acute respiratory syndrome (SARS) in more than 8,000 people in 37 different countries with 10% mortality. In this case, a higher percentage of mortality (~ 40%), was observed that resulted from the virus capacity to promote extrapulmonary diseases and the release of viral progeny from apical and basolateral respiratory cell surfaces (Warnes et al 2015). In late November 2019, cases of novel pneumonia (COVID-19) in Wuhan, Hubei province, China, (Andersen et al 2020, Jiang et al 2020) were reported, and the disease spread rapidly throughout the world and attained the status of the pandemic as declared by the World Health Organization (WHO) at 11 March 2020. There is no evidence that SARS-CoV-2 results from a genetic manipulation in the laboratory of
