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 ultraviolet (UV) rau lub teeb ci (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 ntau zaus ntawm cov kab mob los ntawm tsev neeg ntawm tus mob coronaviruses. Txoj kev tshawb no tau coj los ntawm xibfwb Hadas Mamane, Tus Thawj Tuav Haujlwm ntawm Engineering Engineering ntawm TAU' s Lub Tsev Kawm Ntawv ntawm Mechnical Engineering, Iby thiab Aladar Fleischman Kws Ua Haujlwm ntawm Engineering. Cov ntawv xov xwm tau luam tawm thaum Lub Kaum Ib Hlis 2020 qhov teeb meem ntawm theJournal ntawm Photochemistry thiab Photobiology B: Biology.
& 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 cev muaj zog, thiab txhawm rau kom cov tshuaj tsuag kom zoo, koj yuav tsum muab lub sijhawm tshuaj rau ua rau saum npoo. 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.
& quot; Peb tshawb pom tias nws yooj yim heev rau tua tus mob coronavirus siv cov qhov muag teeb uas tawg lub teeb ci ultraviolet," nws piav qhia." Peb tua cov kab mob siv hluav taws xob uas siv hluav taws xob pheej yig dua thiab muaj qhov muag pom tau, uas siv hluav taws xob tsawg thiab tsis muaj cov kua hlau mercury zoo li cov qhov muag teev tseg. 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 sim qhov zoo tshaj nthwv dej rau tua tus kabmob (coronavirus) thiab pom tias qhov ntev ntawm 285 nanometers (nm) yuav luag zoo rau kev tua tus kabmob zoo li lub yoj ntawm 265 nm, xav tau tsawg tshaj li 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 kev tiv thaiv kev puas tsuaj thiab ntau lub tswv yim lawv nyuam qhuav tsim los ntawm kev sib xyaw ua kom puas ncaj qha thiab tsis ncaj rau cov kab mob thiab kab mob 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 ntawm Kab Mob Npaws thiab Kab mob ua pa ntawm Sheba Medical Center ntawm Tel HaShomer; thiab Nehemya Friedman los ntawm Tel Hashomer.
