ʻO ka World Health Organization a me ka US Centers for Disease Control e ʻike ʻo nā aerosol ke kumu mua no ka hoʻolaha ʻana o ka maʻi COVID-19. ʻO nā aerosol nā ʻāpana liʻiliʻi o ka wai a i ʻole nā mea ʻē aʻe e hiki ke hoʻomau i ka lewa no ka manawa lōʻihi, liʻiliʻi e komo i ka ʻōnaehana hanu.
Hoʻokuʻu ka poʻe i nā aerosol ke hanu lākou, ʻuʻu, kamaʻilio, hoʻōho a hīmeni paha. Hiki i kēia mau aerosol ke loaʻa i ka maʻi inā loaʻa lākou i ka COVID-19. ʻO ka hanu ʻana i ka nui o nā aerosol coronavirus hiki ke maʻi i ke kanaka. Ma ka koi ʻana i ka poʻe e ʻaʻahu i nā masks, ka hoʻomaikaʻi ʻana i ka ea o loko a me nā ʻōnaehana kānana ea, ka hōʻemi ʻana i ka ʻike pilikino a me ka hōʻemi ʻana i ka nui o nā aerosol i ke kaiapuni nā mea nui no ka pale ʻana i ka hoʻolaha ʻana o COVID-19 aerosol.
He mea weliweli ka noiʻi ʻana i nā maʻi maʻi hou, a he mea kakaʻikahi i loko o nā hale hana me nā pae kiʻekiʻe o ka biosafety. ʻO nā haʻawina āpau a hiki i kēia lā ma nā masks a i ʻole ka hoʻomaʻamaʻa kānana i ka wā maʻi maʻi i hoʻohana i nā mea ʻē aʻe i manaʻo ʻia e hoʻohālike i ka nui a me ke ʻano o nā aerosol SARS-CoV-2. Ke hoʻomaikaʻi nei ka noiʻi hou i kēlā, e hoʻāʻo ana i nā hopena saline aerosolized a me nā aerosol i loaʻa i ka coronavirus mai ka ʻohana like me ka maʻi i hoʻokumu ʻia ai ka COVID-19 akā hoʻopilikia wale i nā ʻiole.
Ua hana ʻo Yun Shen lāua ʻo George Washington University hoahana ʻo Danmeng Shuai i kānana nanofiber e hāʻawi ana i ka uila kiʻekiʻe ma o kahi kulu o ka wai polyvinylidene fluoride i ke kaula wili e pili ana i 300 nanometers ke anawaena—ma kahi o 167 manawa ʻoi aku ka lahilahi ma mua o ka lauoho kanaka. Ua hana kēia kaʻina hana i nā pores he mau micrometers wale nō ke anawaena ma ka ʻili o nā nanofibers, e kōkua ana iā lākou e hopu i ka 99.9 pakeneka o nā aerosol coronavirus.
ʻO keʻano hana hana, i kapaʻia he electrospinning, he kumukūʻai kūpono a hiki ke hoʻohanaʻia no ka hana nuiʻana i nā kānana nanofiber no nā mea pale pono'ī a me nā pūnaewele kānana ea. Ke waiho nei ka Electrospinning i kahi hoʻoili electrostatic ma nā nanofibers, kahi e hoʻonui ai i ko lākou hiki ke hopu i nā aerosol, a ʻo kona porosity kiʻekiʻe e maʻalahi ke hanu ʻoiai ke kau ʻana i kahi kānana nanofiber electrospun.
"Hiki i ka ʻenehana electrospinning ke maʻalahi i ka hoʻolālā a me ka hana ʻana i nā masks a me nā kānana ea," wahi a Prof. Yun Shen. "ʻO ka hoʻohana ʻana i ka ʻenehana electrospinning e hoʻomohala i nā ʻano hou o nā masks a me nā kānana ea he hana kānana maikaʻi, hiki ke hoʻokele waiwai a me ka scalability. ʻO ka hiki ke hoʻokō i nā koi no nā masks a me nā kānana ea ma ke kula.
