Kwiiveki ezili-15 ezidlulileyo, mangaphi amatyeli osule umphezulu ngesibulali-ntsholongwane ngokuphithizela?Uloyiko lwe-COVID-19 lukhokelele izazinzulu ukuba zifunde ngeemveliso ezisekwe kwi-nanotechnology, ukusetyenziswa kweeathom ezimbalwa.Bajonge isisombululo sezinto zokugqoka ezinokuthi zibophe kwizinto eziphathekayo kunye nokukhusela ibhaktheriya (ibhaktheriya, iintsholongwane, i-fungi, iprotozoa) ixesha elide.
Ziipolymers ezisebenzisa isinyithi (ezifana nesilivere kunye nobhedu) okanye i-biomolecules (ezifana ne-immem extracts eyaziwayo ngomsebenzi wabo we-microbial) okanye i-cationic (okt charged positive) iipolymers kunye nokusetyenziswa kwexesha elide lemichiza yeekhemikhali (ezifana ne-ammonia kunye ne-nitrogen).) Ingubo yokukhusela yezinto eziphathekayo isetyenziswe ngokudibeneyo.I-compound inokutshizwa ngetsimbi, iglasi, umthi, ilitye, ilaphu, isikhumba kunye nezinye izinto, kwaye umphumo uhlala kwiveki enye ukuya kwiintsuku ze-90, kuxhomekeke kuhlobo lwendawo esetyenzisiweyo.
Ngaphambi kobhubhane, bekukho iimveliso ze-antibacterial, kodwa ngoku kugxilwe kwiintsholongwane.Ngokomzekelo, uNjingalwazi u-Ashwini Kumar Agrawal, intloko yeSebe le-Textile kunye neFiber Engineering ye-Indian Institute of Technology, eDelhi, iphuhlise i-N9 blue nano yesilivere ngo-2013, enekhono eliphezulu kakhulu lokubambisa kunye nokubulala ibhaktheriya kunezinye isinyithi kunye neepolymers. .Ngoku, uye wavavanya iipropathi ze-antiviral kwaye wahlengahlengisa ikhompawundi ukulwa ne-COVID-19.Wathi amazwe amaninzi, kuquka i-United States, i-China, kunye ne-Australia, baye bafaka izicelo zamalungelo awodwa abenzi beentlobo ezahlukeneyo zesilivere (etyheli kunye ne-brown) ukuseka ukungafani kwentsimbi ngokubhekiselele kucoceko lomphezulu."Nangona kunjalo, isilivere ye-N9 eluhlaza okwesibhakabhaka inelona xesha lide lokukhusela, elinokongezwa ngamaxesha ali-100."
Amaziko kulo lonke ilizwe (ngokukodwa i-IIT) akwizigaba ezahlukeneyo zokuphuhlisa ezi nanoparticles njengeengubo zomphezulu.Phambi kwemveliso esemthethweni nesemthethweni, wonke umntu ulindele ukuba intsholongwane iqinisekiswe ngamalingo entsimi.
Ngokufanelekileyo, isiqinisekiso esifunekayo sidinga ukudlula iilabhoratri ezivunywe ngurhulumente (ezifana ne-ICMR, CSIR, NABL okanye i-NIV), okwangoku zibandakanya kuphela kuphando lwechiza kunye nogonyo.
Ezinye iilabhoratri zabucala eIndiya okanye phesheya sele zivavanye iimveliso ezithile.Ngokomzekelo, i-Germcop, inkampani yokuqala ehlala eDelhi, sele iqalile ukusebenzisa iimveliso ze-antibacterial ezisekelwe emanzini ezenziwe e-United States kwaye ziqinisekiswe yi-EPA ngeenkonzo zokubulala iintsholongwane.Imveliso kuthiwa itshizwe kwisinyithi, i-non-metal, i-tile kunye ne-glass surfaces ukubonelela nge-120 kwiintsuku zokuqala ze-10.Ukukhuselwa kwemini, kwaye inezinga lokubulala le-99.9%.Umseki uGqr. Pankaj Goyal uthe imveliso ifanelekile kwiintsapho ezibeke bodwa abaguli abane-COVID.Uthetha neNkampani yezoThutho yaseDelhi ukuze abulale iintsholongwane ezili-1,000 zeebhasi.Nangona kunjalo, uvavanyo lwenziwe kwilabhoratri yabucala.
Iisampulu ezivela kwi-IIT Delhi zathunyelwa kwi-MSL microbiological test laboratory e-UK ngo-Epreli.Ezi ngxelo zilindeleke kuphela phambi kokuphela kwalo nyaka.Unjingalwazi u-Agrawal uthe: "Uthotho lovavanyo lwaselabhoratri luya kuqinisekisa ukusebenza kwekhompawundi kwindawo eyomileyo, isantya kunye nexesha lokuqhubeka kokubulawa kwale ntsholongwane, nokuba ayinayo ityhefu kwaye ikhuselekile ukuyisebenzisa."
Nangona uNjingalwazi Agrawal's N9 Blue Silver ikwiprojekthi yeNano Mission exhaswa ngemali nguMphathiswa wezeNzululwazi kunye neTekhnoloji kurhulumente waseIndiya, enye iprojekthi exhaswa ngemali yi-IIT Madras kwaye ixhaswa ngemali nguMbutho woPhando lwezoKhuselo kunye noPhuhliso lweSizwe luye lwaphuhliswa kwiikhithi zePPE, iimaski, kunye nabasebenzi bonyango lokuqala.Iiglavu ezisetyenzisiweyo.I-coating ihluza amasuntswana othuli lwe-submicron emoyeni.Nangona kunjalo, usetyenziso lwayo lokwenyani kufuneka luvavanywe kwintsimi, ngoko kufuneka lusonjululwe.
Singakwazi, kodwa ekuhambeni kwexesha, ayilokhetho olunempilo kuthi okanye okusingqongileyo.UGqr. Rohini Sridhar, iGosa eliPhezulu leSibhedlele sase-Apollo eMadurai, uthe ukuza kuthi ga ngoku, i-disinfectants eqhelekileyo esetyenziswa kwiindawo zoluntu ezixineneyo ezifana nezibhedlele kunye neekliniki ziqulethe izisombululo zotywala, i-phosphate okanye i-hypochlorite, edla ngokubizwa ngokuba yi-bleach yasekhaya."Ezi zisombululo zilahlekelwa ngumsebenzi wazo ngenxa yokuphuma komphunga okukhawulezayo kwaye zibole xa zibekwe kukukhanya kwe-ultraviolet (njengelanga), nto leyo efuna ukubulawa kweentsholongwane kumphezulu izihlandlo ezininzi ngemini."
Ngokufunyaniswa kwenqanawa yokuhamba ngenqanawa yeDiamond Princess, i-coronavirus inokuhlala ukuya kuthi ga kwiintsuku ezili-17 kumphezulu, ngenxa yoko kuye kwavela itekhnoloji entsha yokubulala iintsholongwane.Xa i-antiviral coatings yayiphantsi kovavanyo lweklinikhi kumazwe aliqela, kwiinyanga ezintathu ezidlulileyo, izazinzulu ezivela kwi-Haifa Institute of Technology kwa-Israyeli zabanga ukuba zenze iipolymers ezinokuthi zibulale i-coronavirus ngaphandle kokuyinciphisa.
Abaphandi kwiYunivesithi yaseHong Kong yeSayensi kunye neTekhnoloji baye baphuhlisa i-antibacterial coating entsha ebizwa ngokuba yi-MAP-1, enokubulala iibhaktheriya ezininzi kunye neentsholongwane-kubandakanya ii-coronavirus-ukuya kuthi ga kwiintsuku ezingama-90.
Unjingalwazi u-Agrawal uthe ukusukela okokugqibela ubhubhani we-SARS, amazwe amaninzi ebesebenza ekuphuhliseni iipolymers ezingeva lubushushu eziphendula ekuchukunyisweni okanye kungcoliseko lwamathontsi.Uninzi lwezi zinto zenziwe zalungiswa ngexesha lobhubhane kwaye zithengiswa phantsi kwamagama eemveliso ezahlukeneyo eJapan, eSingapore naseUnited States.Nangona kunjalo, ii-arhente zokukhusela umphezulu ezikhoyo ngoku kwimarike yamazwe ngamazwe ziyaphina.
