Kiʻi hae: Hoʻohana ʻia ke kukui ultraviolet mai kahi kukui krypton chloride excimer e nā molekala e neʻe ana ma waena o nā mokuʻāina ikehu like ʻole. (Kumu: Linden Research Group)
Ua ʻike ʻia ka noiʻi hou mai ke Kulanui o Colorado Boulder ʻaʻole maikaʻi loa kekahi mau nalu o ke kukui ultraviolet (UV) i ka pepehi ʻana i ka maʻi i hoʻokumu ʻia ai ka COVID-19, akā ʻoi aku ka palekana o ka hoʻohana ʻana ma nā wahi ākea.
ʻO ke aʻo ʻana, i paʻi ʻia i kēia mahina ma ka puke moʻolelo Applied and Environmental Microbiology, ʻo ia ka loiloi piha mua o nā hopena o nā hawewe like ʻole o ke kukui ultraviolet ma SARS-CoV-2 a me nā maʻi hanu ʻē aʻe, me ka mea hoʻokahi wale nō ka palekana no nā meaola. ʻaʻole koi i nā lōʻihi nalu pili. Palekana.
Kapa nā mea kākau i kēia mau ʻike he "mea hoʻololi pāʻani" no ka hoʻohana ʻana i ke kukui UV e hiki ai ke alakaʻi i nā ʻōnaehana kūpono hou, palekana a maikaʻi hoʻi no ka hōʻemi ʻana i ka laha o nā maʻi ma nā wahi ākea ākea e like me nā mokulele a me nā wahi ʻaha mele.
"Ma kahi kokoke i nā pathogens a mākou i aʻo ai, ʻo kēia maʻi ka mea maʻalahi loa e pepehi me ke kukui ultraviolet," wahi a ka mea kākau kiʻekiʻe ʻo Carl Linden, ke kaukaʻi o ka ʻenekinia kaiapuni. "Pono ia i nā dosis haʻahaʻa loa. Hōʻike kēia i ka ʻenehana UV hiki ke lilo i hopena maikaʻi loa no ka pale ʻana i nā wahi ākea.
Hoʻopuka maoli ʻia nā kukuna Ultraviolet e ka lā, a ʻo ka hapa nui o nā ʻano he mea pōʻino i nā mea ola a me nā microorganism e like me nā maʻi maʻi. Hiki ke hoʻopili ʻia kēia kukui e ka genome o ke kino, e hoʻopaʻa ana i nā puʻupuʻu i loko a pale i ka hana hou ʻana. Eia nō naʻe, ua kānana ʻia kēia mau nalu ʻino mai ka Lā e ka papa ozone ma mua o ka hiki ʻana i ka ʻili honua.
ʻO kekahi mau huahana maʻamau, e like me nā kukui fluorescent, hoʻohana i nā kukui UV ergonomic, akā loaʻa kahi uhi kūloko o ka phosphorus keʻokeʻo e pale iā lākou mai nā kukuna UV.
"Ke wehe mākou i ka uhi, hiki iā mākou ke hoʻokuʻu i nā nalu i hiki ke hōʻino i ko mākou ʻili a me nā maka, akā hiki iā lākou ke pepehi i nā pathogens," wahi a Linden.
Ke hoʻohana nei nā halemai i ka ʻenehana UV e hoʻomaʻemaʻe i nā wahi ma nā wahi i noho ʻole ʻia a me ka hoʻohana ʻana i nā robots e hoʻohana i ke kukui UV ma waena o nā lumi hana a me nā lumi maʻi.
Hiki i nā hāmeʻa he nui ma ka mākeke i kēia lā ke hoʻohana i ke kukui UV e hoʻomaʻemaʻe i nā mea āpau mai ke kelepona hele a i nā hue wai. Akā ke hoʻomohala nei ka FDA a me EPA i nā protocol palekana. Mālama ʻo Linden i ka hoʻohana ʻana i nā mea hana pilikino a i ʻole "sterilizing" e hōʻike i nā kānaka i ke kukui ultraviolet.
Ua ʻōlelo ʻo ia he ʻokoʻa nā ʻike hou no ka mea ke hōʻike nei lākou i ka waena waena ma waena o ke kukui ultraviolet, kahi palekana no ke kanaka a me ka pōʻino i nā maʻi maʻi, ʻoi aku ka maʻi i kumu COVID-19.
Ma kēia noiʻi ʻana, ua hoʻohālikelike ʻo Linden a me kāna hui i nā lōʻihi hawewe like ʻole o ke kukui UV me ka hoʻohana ʻana i nā ala maʻamau i hoʻomohala ʻia ma ka ʻoihana UV.
"Manaʻo mākou e hui pū mākou a hana i nā ʻōlelo maopopo e pili ana i ka nui o ka hoʻolaha ʻana o UV e pono ai e pepehi iā SARS-CoV-2," wahi a Linden. "Makemake mākou e hōʻoia inā ʻoe e hoʻohana i ka kukui UV e hakakā i ka maʻi, e kūleʻa ʻoe ". ʻO ka hoʻopaʻa ʻana e pale i ke olakino kanaka a me ka ʻili kanaka a pepehi i kēia mau pathogens.
Loaʻa nā manawa kūpono e hana i kēlā mau hana e like me ka hana ʻana me SARS-CoV-2 e koi i nā kūlana palekana koʻikoʻi. No laila ʻo Linden lāua ʻo Ben Ma, he hoa postdoctoral ma ka hui ʻo Linden, i hui pū me ka virologist Charles Gerba o ke Kulanui o Arizona i loko o kahi hale hana i laikini ʻia e aʻo i ka maʻi a me kāna mau ʻano.
Ua ʻike ka poʻe noiʻi ʻoiai ʻoi aku ka maʻalahi o nā maʻi maʻi i ke kukui ultraviolet, ʻoi aku ka maikaʻi o kekahi lōʻihi-ultraviolet wavelength (222 nanometers). Hana ʻia kēia hawewe e nā kukui krypton chloride excimer, i hoʻoikaika ʻia e nā molekala e neʻe ana ma waena o nā mokuʻāina ikehu like ʻole a he ikehu kiʻekiʻe loa. No laila, hiki iā ia ke hōʻeha hou aku i nā protein viral a me nā waikawa nucleic ma mua o nā mea hana UV-C ʻē aʻe a paʻa ʻia e nā papa waho o ka ʻili a me nā maka o ke kanaka, ʻo ia hoʻi, ʻaʻohe ona hopena olakino. pepehi i ka ma'i ma'i.
Hiki i nā kukuna UV o nā lō'ihi like 'ole (ana 'ia ma nā nanometers) ke komo i nā papa like 'ole o ka 'ili. ʻOi aku ka hohonu o kēia mau nalu nalu i loko o ka ʻili, ʻoi aku ka nui o ka pōʻino. (Ke kumu kiʻi: "Far UV: Ka Moku'āina o kēia manawa" i paʻi ʻia e ka International Ultraviolet Radiation Association ma 2021)
Mai ka hoʻomaka ʻana o ke kenekulia 20, ua hoʻohana nui ʻia nā ʻano like ʻole o ka radiation UV e hoʻomaʻemaʻe i ka wai, ka ea, a me nā ʻili. I ka hoʻomaka ʻana o ka makahiki 1940, ua hoʻohana ʻia ia e hōʻemi i ka laha ʻana o ka maʻi maʻi i loko o nā halemai a me nā lumi papa ma o ka hoʻomālamalama ʻana i ke kaupaku e hoʻomaʻemaʻe i ka ea e holo ana i loko o ka lumi. I kēia lā, hoʻohana ʻia ʻaʻole i loko o nā halemai wale nō, akā i kekahi mau halepaku ākea a ma nā mokulele i ka wā ʻaʻohe kanaka a puni.
I loko o kahi pepa keʻokeʻo i paʻi hou ʻia e ka International Ultraviolet Society, Far-UV Radiation: Current State of Knowledge (me ka noiʻi hou), ʻo Linden a me nā hoa kākau e hoʻopaʻapaʻa nei e hiki ke hoʻohana ʻia kēia lōʻihi hawewe mamao loa-UV me ka hoʻomaikaʻi ʻana i ka ventila, ke komo ʻana. ʻO nā masks a me ka hoʻopaʻa ʻana he mau hana koʻikoʻi e hoʻēmi i nā hopena o nā maʻi maʻi o kēia manawa a me ka wā e hiki mai ana.
Hiki ke ho'āla a hoʻopau ʻia nā ʻōnaehana Linden Imagine ma nā wahi pani e hoʻomaʻemaʻe mau i ka ea a me nā ʻili, a i ʻole e hana i nā pale ʻike ʻole mau ma waena o nā kumu a me nā haumāna, nā malihini a me nā limahana mālama, a me nā poʻe ma nā wahi kahi hiki ʻole ke mālama ʻia ka hele ʻana o ka nohona.
Hiki i ka disinfection UV ke hoʻokūkū i nā hopena maikaʻi o ka hoʻomaikaʻi ʻana i ka ea o loko, no ka mea hiki iā ia ke hāʻawi i ka pale like me ka hoʻonui ʻana i ka nui o nā loli ea i kēlā me kēia hola i loko o kahi lumi. ʻO ka hoʻokomo ʻana i nā kukui UV ʻoi aku ka liʻiliʻi ma mua o ka hoʻomaikaʻi ʻana i kāu ʻōnaehana HVAC holoʻokoʻa.
"Aia kahi manawa ma aneʻi e mālama i ke kālā a me ka ikaika ʻoiai e pale ana i ke olakino lehulehu. He mea hoihoi loa ia,” wahi a Linden.
