Setšoantšo sa banner: Lebone la ultraviolet le tsoang leboneng la krypton chloride excimer le tsamaisoa ke limolek'hule tse tsamaeang pakeng tsa libaka tse fapaneng tsa matla.(Mohloli: Sehlopha sa Lipatlisiso sa Linden)
Patlisiso e ncha e tsoang Univesithing ea Colorado Boulder e fumane hore maqhubu a mang a khanya ea ultraviolet (UV) ha a sebetse feela ho bolaea vaerase e bakang COVID-19, empa hape a bolokehile ho sebelisoa libakeng tsa sechaba.
Boithuto bona, bo phatlalalitsoeng khoeling ena koranteng ea Applied and Environmental Microbiology, ke tlhahlobo ea pele e felletseng ea litlamorao tsa maqhubu a fapaneng a khanya ea ultraviolet ho SARS-CoV-2 le livaerase tse ling tsa phefumoloho, ho kenyeletsoa eona feela e bolokehileng bakeng sa likokoana-hloko. ha e hloke ho kopana le wavelengths.Sireletsa.
Bangoli ba bitsa liphuputso tsena "ho fetola lipapali" bakeng sa tšebeliso ea lebone la UV le ka lebisang lits'ebetsong tse ncha tse theko e tlaase, tse sireletsehileng le tse sebetsang bakeng sa ho fokotsa ho ata ha livaerase libakeng tse phetheselang tsa sechaba tse kang boema-fofane le libaka tsa konsarete.
Mongoli e moholo Carl Linden, moprofesa oa boenjiniere ba tikoloho, o itse: “Ho hoo e ka bang likokoana-hloko tsohle tseo re ithutileng tsona, kokoana-hloko ena ke e ’ngoe ea tse kotsi ka ho fetisisa ho li bolaea ka khanya ea ultraviolet."E hloka litekanyetso tse tlase haholo.Sena se bontša hore theknoloji ea UV e ka ba tharollo e ntle haholo bakeng sa ho sireletsa libaka tsa sechaba. ”
Mahlaseli a ultraviolet ka tlhaho a ntšoa ke letsatsi, ’me mefuta e mengata e kotsi ho lintho tse phelang hammoho le likokoana-hloko tse kang likokoana-hloko.Leseli lena le ka monngoa ke liphatsa tsa lefutso tsa ntho e phelang, la tlama mafito ho lona le ho le thibela hore le se ke la ikatisa.Leha ho le joalo, maqhubu ana a kotsi a tsoang Letsatsing a sefshoa ke lera la ozone pele a fihla holim’a Lefatše.
Lihlahisoa tse ling tse tloaelehileng, tse kang mabone a fluorescent, li sebelisa mahlaseli a ergonomic UV, empa li na le lesela le ka hare la phosphorus e tšoeu e li sireletsang mahlaseling a UV.
"Ha re tlosa ho roala, re ka ntša maqhubu a maqhubu a ka bang kotsi letlalong le mahlo a rona, empa a ka boela a bolaea likokoana-hloko," ho boletse Linden.
Lipetlele li se li ntse li sebelisa theknoloji ea UV ho bolaea likokoana-hloko libakeng tse se nang batho le ho sebelisa liroboto ho sebelisa mabone a UV lipakeng tsa likamore tsa ho buoa le tsa bakuli.
Lisebelisoa tse ngata tse 'marakeng kajeno li ka sebelisa leseli la UV ho hloekisa ntho e' ngoe le e 'ngoe ho tloha ho liselefouno ho ea ho libotlolo tsa metsi.Empa FDA le EPA li ntse li theha liprothokholo tsa polokeho.Linden o hlokomelisa khahlanong le ho sebelisa thepa leha e le efe ea botho kapa ea "sterilizing" e pepesetsang batho leseli la ultraviolet.
A re liphetho tse ncha li ikhethile hobane li emela sebaka se mahareng lipakeng tsa lebone la ultraviolet, le bolokehileng ho batho ebile le kotsi ho livaerase, haholo vaerase e bakang COVID-19.
Thutong ena, Linden le sehlopha sa hae ba ile ba bapisa maqhubu a fapaneng a maqhubu a leseli la UV ba sebelisa mekhoa e tloaelehileng e ntlafalitsoeng indastering eohle ea UV.
"Re nahana hore ha re bokaneng 'me re etse lipolelo tse hlakileng mabapi le palo ea mahlaseli a kotsi a hlokahalang ho bolaea SARS-CoV-2," Linden o itse."Re batla ho etsa bonnete ba hore haeba u sebelisa lebone la UV ho loantša lefu lena, u tla atleha".Tekanyo ea ho sireletsa bophelo ba batho le letlalo la motho le ho bolaea likokoana-hloko tsena. ”
Menyetla ea ho etsa mosebetsi o joalo ha e fumanehe kaha ho sebetsa le SARS-CoV-2 ho hloka litekanyetso tse thata haholo tsa polokeho.Kahoo Linden le Ben Ma, eo e neng e le seithuti sa postdoctoral sehlopheng sa Linden, ba ile ba ikopanya le setsebi sa vaerase Charles Gerba oa Univesithi ea Arizona laboratoring e nang le tumello ea ho ithuta ka vaerase le mefuta ea eona.
Bafuputsi ba fumane hore le ha livaerase ka kakaretso li le bonolo haholo ho khanya ea ultraviolet, leqhubu le itseng la ultraviolet (222 nanometers) le sebetsa haholo.Leqhubu lena la maqhubu le entsoe ke mabone a krypton chloride excimer, a tsamaisoang ke limolek'hule tse tsamaeang pakeng tsa libaka tse fapaneng tsa matla 'me li na le matla a phahameng haholo.Ka hona, e khona ho baka tšenyo e kholo ho liprotheine tsa vaerase le li-nucleic acid ho feta lisebelisoa tse ling tsa UV-C mme e koetsoe ke likarolo tse kantle tsa letlalo le mahlo a motho, ho bolelang hore ha e na litlamorao tse kotsi tsa bophelo bo botle.e bolaea kokoana-hloko.
Mahlaseli a UV a bolelele bo sa tšoaneng (a lekantsoeng mona ka li-nanometer) a ka phunyeletsa letlalong.Ha maqhubu ana a teba a kenella letlalong, a baka tšenyo e eketsehileng.(Mohloli oa setšoantšo: "UV e Hole: Boemo ba Hona Joale ba Tsebo" e phatlalalitsoeng ke International Ultraviolet Radiation Association ka 2021)
Ho tloha mathoasong a lekholo la bo20 la lilemo, mefuta e sa tšoaneng ea mahlaseli a kotsi e ’nile ea sebelisoa haholo ho bolaea metsi, moea le bokaholimo.Khale koana lilemong tsa bo-1940, e ne e sebelisetsoa ho fokotsa ho ata ha lefuba lipetlele le liphaposing tsa borutelo ka ho khantša siling ho bolaea likokoana-hloko moea o potolohang ka phaposing.Kajeno ha e sebelisoe lipetlele feela, empa hape le matlong a mang a sechaba le ka lifofane ha ho se motho.
Ka pampiri e tšoeu e sa tsoa hatisoa ke International Ultraviolet Society, Far-UV Radiation: Boemo ba Hona Joale ba Tsebo (hammoho le lipatlisiso tse ncha), Linden le bangoli-'moho ba pheha khang ea hore sebaka sena se sireletsehileng sa maqhubu a mahlaseli a kotsi a UV se ka sebelisoa hammoho le moea o ntlafetseng, o apereng. limaske le ente ke mehato ea bohlokoa ea ho fokotsa litlamorao tsa mafu a seoa a hajoale le a kamoso.
Sistimi ea Linden Imagine e ka buloa le ho tima libakeng tse koetsoeng ho hloekisa moea le libaka khafetsa, kapa ho theha litšitiso tse sa bonahaleng lipakeng tsa lefapha la thuto ea matsoho le baithuti, baeti le basebetsi ba tlhokomelo, le batho ba libakeng tseo sebaka sa sechaba se ke keng sa hlokomeloa.

"Ho na le monyetla mona oa ho boloka chelete le matla ha u ntse u sireletsa bophelo bo botle ba sechaba.Ehlile e a thahasellisa, ”ho boletse Linden.
