Qhov tshwm sim ntawm COVID-19 kis thoob qhov txhia chaw tau ua rau muaj kev paub ntau ntxiv txog kev nyiam huv ntawm tus kheej thiab kev ua kom tsis muaj menyuam. Kev zam kom tsis txhob muaj kev hem thawj tuaj yeem ua rau muaj kev ntxhov siab heev-ua rau ntau tus, ua rau peb nrhiav txhua yam txhais tau tias kom muaj kev nyab xeeb ntawm peb tus kheej thiab peb cov neeg hlub. Txawm hais tias kev huv huv ntawm tus kheej yog qhov tseem ceeb, cov cuab yeej thiab thev naus laus zis ntxiv dab tsi tuaj yeem ua haujlwm los ua kom tsis muaj menyuam thiab tshem tawm cov kab mob hauv peb lub tsev?
Ultraviolet illumination tau muag rau cov neeg siv khoom raws li txoj hauv kev kom tsis muaj menyuam thiab tua kab mob. Muab cov ntaub ntawv tsis txaus ntseeg nyob rau lub hlis tsis ntev los no thiab ntau pawg neeg tsis tuaj yeem ncav cuag kev pom zoo, koj tuaj yeem muaj kev tsis ntseeg txog kev lees paub txog kev tswj hwm tus kabmob coronavirus. Yog li ntawd, peb tau muab tso ua ke cov ntaub ntawv hauv qab no rau hauv cov ntawv sau luv luv los qhia koj txog hom tshwj xeeb ntawmUV LEDshaum rau kev siv tshuaj tua kab mob, kom tsis muaj menyuam, thiab tshuaj tua kab mob.
Peb Pawg ntawm Ultraviolet Lub Teeb
Zoo ib yam li pom lub teeb,UV teebencompasses ib tug dav spectrum ntawm wavelengths. Qhov tseem ceeb specification yog ntsuas nyob rau hauv nanometers (nm), nrog ultraviolet tso zis los ntawm wavelengths ntawm 100nm thiab 400nm. Lub teeb ultraviolet tau muab faib ua peb pawg thawj, uas muab qhov tshwj xeeb ntawm hom UV lub teeb, vim nws cov khoom sib txawv raws li wavelength.
UV -A: 315-400 nm
UV -B: 280-315 nm
UV -C: 100-280 nm
Cov teeb pom kev ultraviolet feem ntau pom nyob rau hauv UV-Ib spectrum thiab feem ntau raug xaiv ua "blacklights." Qhov no yog qhov tsawg tshaj plaws ntawm ultraviolet lub teeb, siv rau lub hom phiaj xws li UV curing thiab blacklight painting.
UV-B muaj lub wavelength luv dua thiab yog li muaj zog tshaj UV-A. Ob leeg UV-A thiab UV-B pom nyob rau hauv ntuj tshav ntuj; Txawm li cas los xij, UV-B yog lub luag haujlwm tseem ceeb ntawm lub hnub ci. Ob leeg UV-A thiab UV-B LEDs muaj kev txwv loj hauv lawv lub peev xwm los ua kom tsis muaj menyuam thiab tshem tawm cov kab mob thiab kab mob.
UV-C yog ntu ntawm cov spectrum kom mloog zoo rau thaum tsim kom tsis muaj menyuam uas siv ultraviolet LEDs. Ntev wavelengths nyob rau hauv lub 100-280nm spectrum yog nyiam, nrog rau cov tshwj xeeb tshaj yog nyob rau hauv lub 200-280nm ntau tej zaum kuj raug xaiv raws li Germicidal UV (GUV). Nyob rau hauv sib piv rau UV-A thiab UV-B, UV-C wavelengths yog obstructed los yog absorbed los ntawm ozone txheej thiab cua, tiv thaiv lawv los ntawm kev mus txog lub ntiaj teb nto. UV-C yog lub teeb zoo tshaj plaws rau kev tshem tawm cov kab mob, txawm hais tias nws ua rau muaj kev phom sij loj rau tib neeg kev noj qab haus huv. Thaum tsis muaj ib txoj hauv kev los siv cov hluav taws xob ntuj UV-C, peb yuav tsum nrhiav qhov chaw tsim khoom ntawm UV-C lub teeb.
Mechanisms of UV-C in Virus Inactivation
Rau kev ua kom tsis muaj menyuam thiab kev siv tshuaj tua kab mob, UV-C LEDs yuav tsum tau siv, vim tias luv luv wavelengths muaj qhov cuam tshuam loj tshaj plaws rau DNA thiab RNA ntawm cov kab mob.
DNA thiab RNA? Nws zoo li chav kawm Science, puas yog?
Nov yog cov ntsiab lus luv luv ntawm UV-C LEDs hloov DNA thiab RNA, uas yog qhov tseem ceeb rau lub neej, suav nrog cov kab mob thiab kab mob (cov kab mob, kab mob, thiab lwm yam). Thaum tsis muaj cov khoom siv caj ces, tus kab mob yuav tsis muaj peev xwm ntawm kev yug me nyuam, yog li tshem tawm cov kab mob sib kis.
Deoxyribonucleic Acid Helix
DNA thiab RNA yog tsim los ntawm tsib nucleobases nyob rau hauv tag nrho. Thawj peb lub nucleobases tam sim no hauv DNA thiab RNA yog Cytosine (C), Guanine (G), thiab Adenine (A). Qhov kawg ob yog qhov tshwj xeeb tshaj plaws, qhia tias Thymine (T) tshwj xeeb rau DNA, thaum Uracil hloov Thymine hauv RNA helix.
Cov kev tshawb fawb qhia tias raug rauUV -Cwavelengths ua rau thymine thiab uracil molecules nqus ultraviolet hluav taws xob thiab dhau los ua cov tshuaj hloov pauv. Qhov kev hloov pauv no rhuav tshem cov hlwb los ntawm kev ua kom muaj kev puas tsuaj thiab inhibits cov kab mob kev loj hlob. Txoj kev no zoo tshaj plaws nyob ib ncig ntawm 265 nanometers. Ntev wavelengths, xws li cov nyob rau hauv UV-A thiab UV-B, pom kev nqus tsis zoo thiab yog li tsis muaj txiaj ntsig rau kev ua kom tsis muaj menyuam.
Lo lus nug hnub no yog…
Puas yog UV-C LEDs tshem tawm COVID-19 tus kabmob coronavirus?
Laboratory testing about the new coronavirus (SARS{0}}CoV-2) andUV-C LEDsyog txwv; Txawm li cas los xij, kev tshawb fawb yav dhau los ntawm cov kab mob ua ntej tau ua rau ntau tus neeg lees paub nws cov txiaj ntsig. Ib qho kev sib tw tseem ceeb yog tias UV-C yog nqus tau los ntawm huab cua, xav tau tias UV-C qhov chaw muaj lub zog txaus kom ncav cuag lawv lub hom phiaj ntawm qhov deb.
Thaum lub Plaub Hlis, Seoul Viosys tau pom qhov lawv lees paub yog thawj 99.9% kev ua kom tsis muaj menyuam ntawm SARS-CoV-2 tus kab mob los ntawmUV-C LEDs. Cov kev sim no tau ua nrog kev koom tes nrog cov kws tshaj lij los ntawm pab pawg hauv Kauslim University. Cov kev sim tau pom tias Violed UV-C LED modules tuaj yeem tshem tawm 99.9 feem pua ntawm SARS-CoV-2 tus kab mob nrog tsuas yog 30-thib ob ntawm qhov deb ntawm 3 cm. Tu siab, lawv tsis tau nthuav tawm tus naj npawb ntawmLEDssiv los ua qhov no.
