Ua iloa uma e le Faalapotopotoga o le Soifua Maloloina a le Lalolagi ma le US Centers for Disease Control o aerosol o le auala autu lea mo le faasalalauina o le COVID-19 virus. Aerosols o ni vaega laiti o le vai po'o isi mea e mafai ona tumau pea i luga o le ea mo se taimi umi, laiti e ulu i totonu o le manava.
E faamatuu atu e tagata aerosol pe a manava, tale, tautala, alalaga pe pepese. O nei aerosol e mafai fo'i ona iai le siama pe a a'afia ile COVID-19. O le manavaina o le tele o coronavirus aerosol e mafai ona maʻi ai se tagata. E ala i le manaʻomia o tagata e fai matapulepule, faʻaleleia le faʻaleleia o le ea i totonu ma le faʻamamaina o le ea, faʻaitiitia le faʻaalia o le tagata lava ia ma faʻaitiitia le aofaʻi o aerosol i le siosiomaga o mea ia e ave i ai le faamuamua mo le taofiofia o le sosolo o le COVID-19 aerosol.
O su'esu'ega i fa'ama'i fou fa'ama'i e mata'utia, ma e seasea maua i totonu o fale su'esu'e e maualuga le maualuga o le biosafety. O suʻesuʻega uma e oʻo mai i le taimi nei i matapulepule poʻo le faʻamamaina lelei i le taimi o le faʻamaʻi na faʻaaogaina isi mea e manatu e faʻataʻitaʻia le tele ma amioga a le SARS-CoV-2 aerosol. O le suʻesuʻega fou e faʻaleleia i lena, suʻega aerosolized saline solutions ma aerosol o loʻo iai le coronavirus mai le aiga lava e tasi ma le siama e mafua ai le COVID-19 ae naʻo le afaina o isumu.
Yun Shen and George Washington University colleague Danmeng Shuai created a nanofiber filter that delivers a high voltage through a drop of polyvinylidene fluoride liquid to a spinning thread about 300 nanometers in diameter—about 167 times thinner than a human hair . This process created pores just a few micrometers in diameter on the nanofibers’ surface, helping them capture 99.9 percent of coronavirus aerosols.
O le gaosiga o metotia, e taʻua o le electrospinning, e taugofie ma e mafai ona faʻaaogaina e faʻateleina ai le faʻaogaina o nanofiber filiga mo mea e puipuia ai le tagata lava ia ma faʻaogaina o le ea. O le fa'aogaina o le eletise e tu'u ai fo'i se tau eletise i luga o nanofibers, lea e fa'aleleia atili ai lo latou gafatia e pu'eina aerosol, ma o lona porosity maualuga e fa'afaigofie ai ona manava a'o ofuina se fa'amama nanofiber electrospun.
“Electrospinning technology can facilitate the design and manufacture of masks and air filters,” said Prof. Yun Shen. “Using electrospinning technology to develop new types of masks and air filters has good filtration performance, economic feasibility and scalability. Being able to meet the demand for masks and air filters in the field is very promising.”
