Hauv 15 lub lis piam dhau los, koj tau so pes tsawg zaus nrog cov tshuaj tua kab mob frantically?Qhov kev ntshai ntawm COVID-19 tau coj cov kws tshawb fawb los kawm cov khoom lag luam raws li nanotechnology, kev siv ob peb lub atoms.Lawv tab tom nrhiav kev daws teeb meem rau cov txheej txheem saum npoo uas tuaj yeem txuas rau cov ntaub ntawv thiab tiv thaiv kab mob (cov kab mob, kab mob, fungi, protozoa) tau ntev.
Lawv yog cov polymers uas siv cov hlau (xws li nyiaj thiab tooj liab) los yog biomolecules (xws li immem extracts paub rau lawv cov microbial kev ua si) los yog cationic (xws li zoo them) polymers nrog rau lub sij hawm ntev siv cov tshuaj sib txuas (xws li ammonia thiab nitrogen).) Cov khoom siv tiv thaiv txheej siv ua ke.Cov khoom sib xyaw tuaj yeem txau rau ntawm cov hlau, iav, ntoo, pob zeb, ntaub, tawv thiab lwm yam ntaub ntawv, thiab cov nyhuv yuav kav ntev li ib lub lis piam mus rau 90 hnub, nyob ntawm seb hom siv nto.
Ua ntej muaj kev sib kis, muaj cov khoom siv tshuaj tua kab mob, tab sis tam sim no lub hom phiaj tau hloov mus rau cov kab mob.Piv txwv li, xibfwb Ashwini Kumar Agrawal, tus thawj coj ntawm Textile thiab Fiber Engineering Department ntawm Indian Institute of Technology, Delhi, tau tsim N9 xiav nano nyiaj hauv xyoo 2013, uas muaj peev xwm ntau dua los cuab thiab tua cov kab mob ntau dua li lwm cov hlau thiab polymers. .Tam sim no, nws tau soj ntsuam cov cuab yeej tiv thaiv kab mob thiab hloov kho qhov sib xyaw kom tiv thaiv COVID-19.Nws tau hais tias ntau lub tebchaws, suav nrog Tebchaws Meskas, Tuam Tshoj, thiab Australia, tau thov rau patents rau ntau hom nyiaj (daj thiab xim av) los tsim kom muaj qhov tshwj xeeb ntawm cov hlau nyob rau hauv cov nqe lus ntawm kev tu cev."Txawm li cas los xij, N9 xiav nyiaj muaj lub sijhawm tiv thaiv ntev tshaj plaws, uas tuaj yeem nce ntxiv 100 npaug."
Cov tsev kawm ntawv thoob plaws lub tebchaws (tshwj xeeb yog IIT) yog nyob rau theem sib txawv ntawm kev tsim cov nanoparticles no ua cov txheej txheej saum npoo.Ua ntej kev tsim khoom raug cai thiab raug cai, txhua tus tab tom tos tus kab mob no kom paub tseeb los ntawm kev sim ua haujlwm.
Qhov zoo tshaj plaws, daim ntawv pov thawj xav tau yuav tsum dhau los ntawm tsoomfwv cov chaw kuaj mob (xws li ICMR, CSIR, NABL lossis NIV), uas tam sim no tsuas yog koom nrog kev tshawb fawb tshuaj thiab tshuaj tiv thaiv.
Qee lub chaw kuaj mob ntiag tug hauv Is Nrias teb lossis txawv teb chaws tau sim qee yam khoom.Piv txwv li, Germcop, lub tuam txhab pib ua lag luam nyob hauv Delhi, tau pib siv cov khoom siv tshuaj tua kab mob hauv dej hauv Tebchaws Meskas thiab tau lees paub los ntawm EPA rau kev pabcuam tshuaj tua kab mob.Cov khoom lag luam tau hais tias yuav tsum tau txau rau ntawm cov hlau, tsis yog hlau, pobzeb thiab iav qhov chaw kom txog li 120 zaug hauv thawj 10 hnub.Kev tiv thaiv hnub, thiab muaj kev tua tus nqi ntawm 99.9%.Tus tsim Dr. Pankaj Goyal tau hais tias cov khoom lag luam tsim nyog rau cov tsev neeg uas tau cais cov neeg mob COVID-zoo.Nws tab tom tham nrog Delhi Thauj Tuam Txhab kom tua kab mob 1,000 lub tsheb npav.Txawm li cas los xij, qhov kev sim no tau ua nyob rau hauv ib lub chaw kuaj mob ntiag tug.
Cov qauv ntawm IIT Delhi raug xa mus rau MSL microbiological kuaj kuaj hauv UK thaum lub Plaub Hlis.Cov ntawv ceeb toom no tsuas yog xav tau ua ntej kawg ntawm lub xyoo no.Xib fwb Agrawal tau hais tias: "Ib qhov kev sim tshuaj ntsuam xyuas yuav ua kom paub tseeb tias qhov ua tau zoo ntawm cov khoom sib xyaw hauv lub xeev qhuav, qhov nrawm thiab lub sijhawm ntawm kev tua tus kab mob txuas ntxiv, thiab seb nws puas tsis muaj tshuaj lom thiab siv tau zoo."
Txawm hais tias xibfwb Agrawal's N9 Blue Silver belongs rau Nano Lub Hom Phiaj project tau txais nyiaj los ntawm Ministry of Science thiab Technology ntawm tsoomfwv Indian, lwm txoj haujlwm tau txais nyiaj los ntawm IIT Madras thiab tau txais nyiaj los ntawm National Defense Research thiab Development Organization tau tsim rau cov khoom siv PPE, qhov ncauj qhov ntswg, thiab cov neeg ua haujlwm kho mob thawj zaug.Siv hnab looj tes.Cov txheej lim dej submicron plua plav hauv huab cua.Txawm li cas los xij, nws daim ntawv thov tiag tiag yuav tsum tau mus kuaj xyuas, yog li nws yuav tsum tau daws.
Peb tuaj yeem ua tau, tab sis nyob rau lub sijhawm ntev, lawv tsis yog kev xaiv noj qab haus huv rau peb lossis ib puag ncig.Dr. Rohini Sridhar, Tus Thawj Saib Xyuas Kev Ua Haujlwm ntawm Apollo Tsev Kho Mob hauv Madurai, tau hais tias txog tam sim no, cov tshuaj tua kab mob uas siv rau hauv cov chaw pej xeem siab xws li tsev kho mob thiab tsev kho mob muaj cawv, phosphate lossis hypochlorite cov tshuaj, uas feem ntau hu ua tshuaj bleach hauv tsev."Cov kev daws teeb meem no poob lawv txoj haujlwm vim yog evaporation sai thiab decompose thaum raug ultraviolet lub teeb (xws li lub hnub), uas yuav tsum tau tua kab mob ntawm qhov chaw ntau zaus hauv ib hnub."
Raws li kev tshawb pom ntawm Pob Zeb Diamond Princess nkoj nkoj, tus mob coronavirus tuaj yeem nyob ntev txog 17 hnub ntawm qhov chaw, yog li cov cuab yeej tshuaj tua kab mob tshiab tau tshwm sim.Thaum cov tshuaj tiv thaiv kab mob tau raug kuaj xyuas hauv ntau lub tebchaws, peb lub hlis dhau los, cov kws tshawb fawb los ntawm Haifa Institute of Technology hauv Ixayees tau thov kom tau tsim cov tshuaj tiv thaiv kab mob uas tuaj yeem tua tus kabmob coronavirus yam tsis tau txo qis.
Cov kws tshawb fawb ntawm Hong Kong University of Science thiab Technology kuj tau tsim cov tshuaj tiv thaiv kab mob tshiab hu ua MAP-1, uas tuaj yeem tua cov kab mob feem ntau thiab cov kab mob-xws li tus mob coronaviruses-rau 90 hnub.
Xib fwb Agrawal tau hais tias txij li kev kis tus kabmob SARS zaum kawg, ntau lub tebchaws tau ua haujlwm los tsim cov khoom siv hluav taws xob kub-sensitive polymers uas teb rau kev kov lossis dej paug.Ntau yam ntawm cov qauv no tau hloov kho thaum lub sijhawm muaj kev sib kis thoob ntiaj teb thiab raug muag raws li cov npe sib txawv hauv Nyiv, Singapore thiab Tebchaws Meskas.Txawm li cas los xij, cov tshuaj tiv thaiv saum npoo tam sim no muaj nyob rau hauv kev ua lag luam thoob ntiaj teb yog pinchable.
* Peb cov phiaj xwm kev tso npe digital tam sim no tsis suav nrog e-daim ntawv, cov lus sib dhos sib dhos, iPhone, iPad mobile apps thiab cov ntaub ntawv luam tawm.Peb txoj kev npaj tuaj yeem txhim kho koj txoj kev nyeem ntawv.
Nyob rau lub sijhawm nyuaj no, peb tau muab cov ntaub ntawv tshiab tshaj plaws rau koj txog kev txhim kho hauv Is Nrias teb thiab lub ntiaj teb, uas cuam tshuam nrog peb txoj kev noj qab haus huv thiab kev noj qab haus huv, peb lub neej thiab kev ua neej nyob.Txhawm rau kom nthuav dav cov xov xwm uas yog nyob rau hauv cov pej xeem nyiam, peb tau nce tus naj npawb ntawm cov ntawv nyeem dawb thiab txuas ntxiv lub sijhawm sim dawb.Txawm li cas los xij, peb muaj cov cai rau cov neeg siv uas tuaj yeem sau npe: thov ua li ntawd.Thaum peb cuam tshuam nrog cov ntaub ntawv tsis tseeb thiab cov ntaub ntawv tsis tseeb thiab ua raws li lub sijhawm, peb yuav tsum tau nqis peev ntau ntxiv hauv kev tshaj tawm xov xwm.Peb tau cog lus tias yuav muab cov xov xwm zoo tshaj plaws yam tsis muaj kev cuam tshuam los ntawm kev txaus siab thiab kev tshaj tawm nom tswv.
Koj qhov kev txhawb nqa rau peb kev sau xov xwm yog qhov tseem ceeb heev.Qhov no yog kev txhawb nqa ntawm cov xovxwm kom muaj tseeb thiab ncaj ncees.Nws pab peb ua kom nrawm nrog lub sijhawm.
Hinduism yeej ib txwm sawv cev rau kev sau xov xwm hauv pej xeem nyiam.Lub sijhawm nyuaj no, kev nkag mus rau cov ntaub ntawv uas cuam tshuam nrog peb txoj kev noj qab haus huv thiab kev noj qab haus huv, peb lub neej thiab kev noj qab haus huv tseem ceeb dua.Raws li ib tus neeg siv khoom, koj tsis yog tsuas yog cov neeg tau txais txiaj ntsig ntawm peb txoj haujlwm, tab sis kuj yog tus txhawb nqa.
Peb kuj rov hais dua ntawm no tias peb pab neeg ntawm cov neeg sau xov xwm, cov kws sau ntawv, cov neeg tshawb xyuas qhov tseeb, cov kws tsim qauv thiab cov kws yees duab yuav lav muab cov xov xwm zoo yam tsis ua rau muaj kev txaus siab thiab kev tshaj tawm nom tswv.
