Emavikini angu-15 adlule, usule kangaki indawo ngesibulala-magciwane ngokuphithizela?Isici sokwesaba i-COVID-19 siholele ososayensi ukuthi bafunde imikhiqizo esekelwe ku-nanotechnology, ukusetshenziswa kwama-athomu ambalwa.Bafuna isisombululo sezingubo ezingaphezulu ezingabambisana nezinto futhi zivikele amagciwane (amabhaktheriya, amagciwane, isikhunta, i-protozoa) isikhathi eside.
Zingama-polymer asebenzisa izinsimbi (njengesiliva nethusi) noma ama-biomolecules (njengezinto ezikhishwe ze-immem ezaziwa ngomsebenzi wawo we-microbial) noma ama-polymers e-cationic (okungukuthi ashajwe kahle) asebenzisa izinhlanganisela zamakhemikhali isikhathi eside (njenge-ammonia ne-nitrogen).) Indwangu yokuvikela esetshenziswayo ihlangene.I-compound ingafuthwa ngensimbi, ingilazi, izinkuni, itshe, indwangu, isikhumba nezinye izinto, futhi umphumela uthatha isonto elilodwa kuya ezinsukwini ezingu-90, kuye ngokuthi uhlobo lwendawo esetshenzisiwe.
Ngaphambi kwalolu bhubhane, bekunemikhiqizo elwa namagciwane, kepha manje sekugxilwe kumagciwane.Isibonelo, uSolwazi Ashwini Kumar Agrawal, inhloko yoMnyango Wezindwangu kanye Nefiber Engineering we-Indian Institute of Technology, eDelhi, usungule isiliva le-N9 blue nano ngo-2013, elinekhono eliphezulu kakhulu lokucupha nokubulala amagciwane kunezinye izinsimbi nama-polymers. .Manje, usehlole izakhiwo ze-antiviral futhi wenza kabusha i-compound ukuze ilwe ne-COVID-19.Uthe amazwe amaningi, okuhlanganisa i-United States, i-China, ne-Australia, afake izicelo zobunikazi bezinhlobo ezahlukene zesiliva (ophuzi nonsuqu) ukuze kutholakale ukuthi insimbi ihlukile ngokwenhlanzeko."Kodwa-ke, i-N9 blue silver inesikhathi eside sokuvikela esisebenzayo, esinganyuka izikhathi eziyi-100."
Izikhungo ezweni lonke (ikakhulukazi i-IIT) zisezigabeni ezihlukene zokuthuthukisa lawa ma-nanoparticles njengama-surface coatings.Ngaphambi kokukhiqizwa ngobuningi okusemthethweni nokusemthethweni, wonke umuntu ulindele ukuthi leli gciwane liqinisekiswe ngokuhlolwa kwenkundla.
Ngokufanelekile, isitifiketi esidingekayo sidinga ukudlula amalabhorethri agunyazwe uhulumeni (njenge-ICMR, CSIR, NABL noma i-NIV), okwamanje ezibandakanya kuphela ocwaningweni lwezidakamizwa nomgomo.
Amanye amalabhorethri azimele e-India noma phesheya aseyihlolile imikhiqizo ethile.Isibonelo, i-Germcop, inkampani eqalayo eseDelhi, isiqalile ukusebenzisa imikhiqizo elwa namagciwane esekelwe emanzini eyenziwe e-United States futhi yaqinisekiswa yi-EPA ngezinsizakalo zokubulala amagciwane.Umkhiqizo kuthiwa uzofuthwa endaweni yensimbi, engeyona eyensimbi, ethayela nasezingilazini ukuze unikeze okungafika ku-120 ezinsukwini eziyi-10 zokuqala.Ukuvikelwa kosuku, futhi kunezinga lokubulala lika-99.9%.Umsunguli uDkt. Pankaj Goyal uthe umkhiqizo ulungele imindeni ehlukanise iziguli ezine-COVID.Ukhuluma neDelhi Transport Company ukuze abulale amagciwane amabhasi ayi-1,000.Nokho, ukuhlolwa kwenziwe elabhorethri ezimele.
Amasampula avela ku-IIT Delhi athunyelwa elabhorethri yokuhlola i-MSL microbiological e-UK ngo-Ephreli.Le mibiko ilindeleke kuphela ngaphambi kokuphela kwalo nyaka.USolwazi u-Agrawal uthe: "Uchungechunge lokuhlolwa kwaselabhorethri luzoqinisekisa ukusebenza kahle kwenhlanganisela esimweni esomile, isivinini kanye nesikhathi sokuqhubeka kokubulawa kwaleli gciwane, nokuthi ayinabo yini ubuthi futhi iphephile ukuyisebenzisa."
Yize iN9 Blue Silver kaProfessor Agrawal iyingxenye yephrojekthi yeNano Mission exhaswe nguMnyango Wezesayensi Nobuchwepheshe kahulumeni waseNdiya, omunye umsebenzi oxhaswe yi-IIT Madras futhi oxhaswe yiNational Defence Research and Development Organisation yakhelwe izinsiza ze-PPE, imaski, kanye nabasebenzi bezokwelapha bomugqa wokuqala.Amagilavu ​​asetshenzisiwe.I-coating ihlunga izinhlayiya zothuli ezingaphansi kwe-submicron emoyeni.Kodwa-ke, ukusetshenziswa kwayo kwangempela kufanele kuhlolwe endaweni, ngakho-ke kudinga ukuxazululwa.
Singakwazi, kodwa ngokuhamba kwesikhathi, akuzona izinqumo ezinempilo kithi noma imvelo.UDkt. Rohini Sridhar, oyiChief Operating Officer yesibhedlela i-Apollo eMadurai, uthe kuze kube manje, izibulala-magciwane ezivamile ezisetshenziswa ezindaweni zomphakathi ezinabantu abaningi njengezibhedlela nemitholampilo ziqukethe izixazululo zotshwala, i-phosphate noma i-hypochlorite, evame ukubizwa ngokuthi i-bleach yasendlini.“Lezi zixazululo zilahlekelwa ukusebenza kwazo ngenxa yokuhwamuka ngokushesha futhi zibole lapho zivezwe ekukhanyeni kwe-ultraviolet (njengelanga), okwenza kudingeke ukuthi indawo engaphezulu ibulawe amagciwane izikhathi eziningi ngosuku.”
Ngokusho kokutholwa komkhumbi wokuhamba nge-Diamond Princess, i-coronavirus ingahlala izinsuku eziyi-17 ngaphezulu, ngakho-ke sekuvele ubuchwepheshe obusha bokubulala amagciwane.Ngenkathi izimbotshana ezilwa namagciwane zihlolwa emitholampilo emazweni amaningi, ezinyangeni ezintathu ezedlule, ososayensi be-Haifa Institute of Technology kwa-Israel bathi benze ama-polymers alwa namagciwane angabulala i-coronavirus ngaphandle kokuyehlisa.
Abaphenyi baseHong Kong University of Science and Technology baphinde benza i-antibacterial coating entsha ebizwa ngokuthi i-MAP-1, engabulala amagciwane amaningi namagciwane-kuhlanganise nama-coronavirus-izinsuku ezingafika kwezingama-90.
USolwazi u-Agrawal uthe selokhu kwaba nobhubhane lokugcina lwe-SARS, amazwe amaningi abesebenzela ukuthuthukisa ama-polymers angezwani nokushisa asabela ekungcoleni kokuthinta noma kwamaconsi.Eziningi zalezi zakhiwo zishintshiwe phakathi nobhubhane olukhona futhi zithengiswa ngaphansi kwamagama emikhiqizo ehlukene eJapan, Singapore nase-United States.Kodwa-ke, ama-ejenti okuvikela angaphezulu atholakalayo njengamanje emakethe yamazwe ngamazwe ayaphinwa.
