Named after scientists from the Department of Nanostructured, Fibrous and Composite Materials. artificial intelligence St. Meosa from the St. Petersburg State University of Industrial Technologies and Design (SPbGUPTD) has developed an adsorbent bactericidal material based on carbon fiber and gold and silver nanoparticles. The material will be used in the production of filters for ventilation systems installed in hospitals to combat hospital-acquired infections. The Ministry of Education and Science of the Russian Federation told socialbites.ca about this.
Today, carbon filters are used in ventilation systems as well as HEPA filters, which are a type of high-efficiency air filter. However, colonies of viruses and bacteria can grow on the surface of HEPA filters, resulting in the release of a larger amount of pathogens at the outlet, and the use of carbon granules for placement in the filter device is undesirable. The material proposed by scientists from St. Petersburg solves both problems: it is more convenient to use, and due to its sorption properties, colonies of pathogens do not grow on it.
“Since carbon fiber is an absorbent material, we plan to use it as a filter in ventilation systems in hospitals. Contaminants contaminate the fiber and form new chemical compounds with activated carbon as they remain on the filter. We have developed a technology that allows us to create carbon fiber filters that retain not only pollutants, but also viruses and bacteria, which is extremely important to solve the problem of death from hospital-acquired infections,” the assistant of the Department of Nanostructured, Fibrous and Composite Materials told socialbites.ca. artificial intelligence Meosa SPbGUPTD Nadezhda Uvarova.
Carbon fiber supplied to Russia from Belarus is used to create a new material. Scientists from the University of Industrial Technology and Design managed to add gold and silver nanoparticles to carbon fiber. It should be added that gold is used in such small quantities that it does not increase the cost of the material.
“Silver is cytotoxic, meaning it is toxic to the cells of some human organs. Therefore, the Russian Academy of Sciences St. We are conducting an experiment of adding gold to the material, for which we have been able to prove its bactericidal properties thanks to the method of the St. Petersburg Federal Research Center. “We found that gold in nanoparticles is bactericidal but does not destroy body cells,” Uvarova added.
