Vese World Health Organisation neUS Centers for Disease Control vanobvuma kuti aerosols ndiyo nzira yekutanga yekupararira kwehutachiona hweCOVID-19. Aerosols zvimedu zvidiki zvemvura kana zvimwe zvinhu zvinogona kuramba zvakaturikwa mumhepo kwenguva yakareba, zvidiki zvekupinda mukati mekufema.
Vanhu vanoburitsa aerosol pavanofema, kukosora, kutaura, kupopota kana kuimba. Aya maaerosols anogona zvakare kuve nehutachiona kana akabatwa neCCIDID-19. Kufemba huwandu hwakakwana hwekoronavirus aerosols kunogona kurwarisa munhu. Nekuda kuti vanhu vapfeke masiki, kuvandudza kufefetedza kwemukati uye mafirita emhepo, kudzikisira kuratidzwa kwevanhu uye kudzikisa huwandu hwese hwema aerosols munharaunda ndizvo zvekutanga kudzikamisa kupararira kweCOVID-19 aerosols.
Tsvagiridzo yehutachiona hutsva hunotapukira ine njodzi, uye haiwanzo kuwanikwa mumarabhoritari ane mazinga epamusoro ekuchengetedza zvipenyu. Zvidzidzo zvese kusvika parizvino pamasiki kana kusefa zvakanaka panguva yedenda zvakashandisa zvimwe zvinhu zvinofungidzirwa kutevedzera saizi uye maitiro eSARS-CoV-2 aerosols. Chidzidzo chitsva ichi chinonatsiridza pane izvo, kuyedza aerosolized saline mhinduro uye aerosols ine coronavirus kubva kumhuri imwechete sehutachiona hunokonzera COVID-19 asi hunongobata mbeva.
Yun Shen nemumwe waaishanda naye kuGeorge Washington University Danmeng Shuai vakagadzira nanofiber sefa inopa simba repamusoro kuburikidza nedonhwe repolyvinylidene fluoride fluid kusvika kune shinda inotenderera dhayamita 300 nanometers — kutetepa zvakapetwa ka167 pane bvudzi remunhu. Maitiro aya akagadzira pores angori mashoma mamicrometer mudhayamita pane nanofibers 'pamusoro, achivabatsira kutora 99.9 muzana yekoronavirus aerosols.
Iyo nzira yekugadzira, inozivikanwa se electrospinning, inodhura-inoshanda uye inogona kushandiswa kuburitsa-nanofiber mafirita emidziyo yekudzivirira uye mafirita emhepo. Electrospinning inosiyawo electrostatic charge pane nanofibers, iyo inosimudzira kugona kwavo kubata aerosols, uye yakakwirira porosity inoita kuti zvive nyore kufema paunenge wakapfeka electrospun nanofiber sefa.
"Electrospinning tekinoroji inogona kufambisa dhizaini nekugadzirwa kwemasiki uye mafirita emhepo," akadaro Prof. Yun Shen. "Kushandisa tekinoroji yemagetsi kugadzira mhando nyowani dzemasiki uye mafirita emhepo ane kusefa kwakanaka, kugona kwehupfumi uye scalability. Kukwanisa kuzadzisa kudiwa kwemask uye mafirita emhepo mumunda kunovimbisa."
