Cov kws tshawb nrhiav los ntawm Tel Aviv University (TAU) tau ua pov thawj tias tus kabmob coronavirus tuaj yeem tua tau zoo, sai sai, thiab pheej yig siv cov duab hluav taws xob tua UV (UV-LEDs). Lawv ntseeg tias UV-LED technology tsis ntev yuav muaj kev lag luam ntiag tug thiab kev lag luam.
Nov yog thawj zaug kev kawm tshawb fawb txog ntawm kev ua haujlwm ntawm kev ua haujlwm ntawm kev ua kom zoo rau UV-LED qhov kev cuam tshuam ntawm kev sib txawv ntawm qhov ntev lossis nthwv ntawm cov kab mob los ntawm tsev neeg ntawm tus mob coronaviruses. Txoj kev tshawb no tau coj los ntawm xibfwb Hadas Mamane, Lub Tsev Haujlwm Saib Xyuas Ib Puag Ncig ntawm TAU' s Lub Tsev Kawm Ntawv ntawm Mechnical Engineering, Iby thiab Aladar Fleischman Kws Qhia Txuj Ci. Cov kab lus no tau luam tawm thaum Lub Kaum Ib Hlis 2020 qhov xwm ntawm Journal of Photochemistry thiab Photobiology B: Biology.
GG quot; Tag nrho lub ntiaj teb tam sim no tab tom nrhiav cov kev daws teeb meem zoo los tua cov kab mob coronavirus," hais tias xibfwb Mamane." Qhov teeb meem yog tias txhawm rau tua cov tsheb npav, tsheb ciav hlau, chav kis las, lossis dav hlau los ntawm kev txau tshuaj, koj xav tau lub zog ntawm lub cev, thiab txhawm rau kom cov tshuaj tsuag kom zoo, koj yuav tsum muab lub sijhawm tshuaj lom neeg los ua nto. Kev rho tawm kab mob raws li LED qij, txawm li cas los xij, tuaj yeem ntsia tau rau hauv lub tshuab tso pa thiab cua txias, piv txwv li, thiab ua kom tsis muaj pa tawm hauv huab cua thiab tom qab ntawd tawm mus rau hauv chav.
GG quot; Peb tshawb pom tias nws yooj yim heev los tua tus mob coronavirus siv cov qhov muag teeb uas tawg lub teeb ci ci rau UV," nws piav qhia." Peb tua cov kab mob siv pheej yig thiab yooj yim muaj LED qhov muag teev, uas siv hluav taws xob tsawg thiab tsis muaj cov kua hlau mercury zoo li cov qhov muag teeb li niaj zaus. Peb cov kev tshawb fawb muaj kev lag luam thiab kev coj ua hauv zej zog, muab qhov muaj peev xwm siv xws li cov qhov muag LED hauv txhua qhov chaw ntawm peb lub neej, nyab xeeb thiab sai."
Cov kws tshawb nrhiav tau soj ntsuam pom qhov zoo tshaj ntawm qhov yuag tua cov kab mob coronavirus thiab pom tias qhov ntev ntawm 285 nanometers (nm) yuav luag zoo rau kev tua tus kab mob ua rau yoj yoj ntawm 265 nm, xav tau tsawg dua ib nrab ntawm ib feeb kom rhuav tshem ntau dua 99.9% ntawm cov khaus laus nas vais lav. Qhov txiaj ntsig no tseem ceeb vim tias tus nqi ntawm 285 nm LED qij tau qis dua qis dua li ntawm 265 nm qhov muag teev, thiab cov qub kuj tseem npaj tau ntxiv.
Thaum kawg, raws li kev tshawb fawb nthuav dav, kev lag luam yuav tuaj yeem tsim kho qhov tsim nyog thiab teeb tsa cov qhov muag teev hauv cov tshuab lim lossis cua txias, lub tshuab nqus tsev, thiab lub tshuab ua dej, thiab thiaj li muaj peev xwm ua kom huv qhov chaw loj thiab thaj chaw. Professor Mamane ntseeg tias yuav thev naus laus zis rau kev siv kom ze rau yav pem suab.
Tseem ceeb kom nco ntsoov tias nws yog qhov txaus ntshai heev uas sim siv txoj hau kev tua kab mob sab hauv tsev. Yuav kom muaj txiaj ntsig zoo, ib qho system yuav tsum tau tsim kom ib tug neeg tsis ncaj qha mus rau lub teeb.
Hauv lub neej yav tom ntej, cov kws tshawb nrhiav yuav sim lawv cov kev sib txuas ntawm cov txheej txheem kev puas tsuaj thiab ntau lub tswv yim uas lawv nyuam qhuav tsim los ntawm kev sib xyaw ua kom puas cov kab mob thiab kev puas tsuaj rau ntawm ntau qhov chaw, huab cua, thiab dej.
Txoj kev tshawb no tau ua nrog kev koom tes nrog xibfwb Yoram Gerchman ntawm Oranim College; Dr. Michal Mandelboim, Tus Thawj Coj ntawm National Center rau Kab Mob Npaws thiab Kab mob ua pa ntawm Sheba Medical Center ntawm Tel HaShomer; thiab Nehemya Friedman los ntawm Tel Hashomer.
