Qhov kev tshwm sim tsis ntev los no ntawm COVID-19 tau ua rau muaj kev tshawb nrhiav loj rau cov kev daws teeb meem uas tuaj yeem tiv thaiv kev kis tus kabmob tuag - los ntawm cov kws tshawb fawb thiab cov kws tshawb fawb tau cog lus los nrhiav kev daws teebmeem, rau cov tuam txhab thiab cov neeg siv khoom nrhiav cov ntaub ntawv ntseeg tau. Nyob rau lub sijhawm tsis paub tseeb no, ntau tus tab tom nrhiav cov ntaub ntawv nyob ib puag ncig cov thev naus laus zis uas tuaj yeem siv los tawm tsam tus kabmob. Ib txoj hauv kev ua pov thawj yog siv lub teeb UV.

Kev cuam tshuam DNA ntawm cov kab mob nrog UV teeb
UVC lub teeb yog ib qho kev siv tshuab ua kom tsis muaj menyuam uas tau pom tias ua rau muaj ntau yam kab mob, suav nrog- tab sis tsis txwv rau- MRSA, C. diff, E. Coli thiab Pseudomonas. Nyob rau hauv daim ntawv thov UVC lub zog yog absorbed los ntawm nucleic acids nyob rau hauv lub RNA thiab DNA, ua rau covalent daim ntawv cog lus uas, ntawm txoj cai koob, yuav ua rau cov kab mob tsis tuaj yeem rov tsim dua thiab kis tau. Qhov zoo tshaj plaws kev siv tshuaj tua kab mob tshwm sim nrog lub ncov ntawm 260 nm txog 270 nm, qhov zoo tshaj plaws taw tes ntawm DNA absorbs UV zog.

Tau ntau xyoo, UV mercury teeb tau suav tias yog qhov kev xaiv zoo tshaj plaws. Txawm li cas los xij, cov teeb muaj ntau qhov kev txwv, suav nrog kev ua haujlwm qis ntawm lub tub yees txias, kev tsim kho tsis yooj yim, lub sijhawm sov so ntev, kev pheej hmoo ntawm mercury raug, thiab txwv UV emittance ntawm 254nm. Hauv kev sib piv, UV lub teeb-emitting diodes (UVC LEDs) tuaj yeem teeb tsa kom tawm ntawm qhov zoo tshaj plaws ntawm cov kab mob kis kab mob thiab muab cov tshuaj tua kab mob ntseeg tau raws li qhov xav tau yam tsis muaj kev txwv uas cuam tshuam cov teeb mercury.

Qhov kev daws teeb meem zoo hauv kev sim rau COVID-19 kev ua tau zoo
Kev siv UVC LED thev naus laus zis ntawm qhov chaw ua rau muaj kev ntseeg siab, nrawm, raws li kev thov tshuaj tua kab mob rau cov khoom siv me me rau nruab nrab, xws li laptops, xov tooj, keyboards, tsom iav, cov yawm sij thiab cov khoom siv kho mob. Nws tiv thaiv kev kis tus kab mob microbes mus rau thaj chaw muaj kev cuam tshuam loj heev, suav nrog cov tsev kho mob hauv tsev kho mob, chav kuaj thiab chav huv.

Klaran UVC LEDs tsis tau tsuas yog ua pov thawj zoo tiv thaiv cov kab mob loj, xws li C. diff thiab Methicillin-Resistant Staphylococcus Aureus (MRSA), tab sis kuj muaj peev xwm ua tiav qhov txo qis ntawm cov kab mob thiab cov kab mob hauv vib nas this.

Thaum cov kev tshawb fawb tau lees paub tias UVC lub teeb tuaj yeem ua tau zoo rau kev tawm tsam SARS-COV cov kev tshawb fawb ntxiv yog xav tau los txiav txim siab thiab lees paub cov koob tshuaj tshwj xeeb uas yuav tsum tau ua kom tsis txhob siv COVID-19 ntawm ntau qhov chaw thiab cov khoom siv.
