Mumavhiki gumi nemashanu adarika, kangani pawakapukuta pasi nejekiseni uchipengereka?Iyo COVID-19 kutya chinhu chatungamira masayendisiti kudzidza zvigadzirwa zvakavakirwa pananotechnology, mashandisirwo emaatomu mashoma.Vari kutsvaga mhinduro yehuputi hwepamusoro hunogona kusungira kune zvinhu uye kudzivirira mabhakitiriya (bhakitiriya, mavhairasi, fungi, protozoa) kwenguva yakareba.
Iwo mapolymer anoshandisa simbi (senge sirivheri nemhangura) kana biomolecules (senge immem zvinyorwa zvinozivikanwa nekuita kwavo kwemicrobial) kana cationic (kureva inochajiswa zvakanaka) mapolymer ane kushandiswa kwenguva refu kwemakemikari emusanganiswa (seammonia nenitrogen).) Material protective coating inoshandiswa pamwe chete.Mushonga wacho unogona kupfapfaidzwa pasimbi, girazi, huni, dombo, jira, dehwe uye zvimwe zvinhu, uye mhedzisiro yacho inotora kubva vhiki imwe kusvika kumazuva makumi mapfumbamwe, zvichienderana nerudzi rwenzvimbo inoshandiswa.
Pamberi pedenda, pakanga paine zvigadzirwa zveantibacterial, asi iko zvino tarisiro yachinja kune mavhairasi.Semuyenzaniso, Muzvinafundo Ashwini Kumar Agrawal, mukuru weDhipatimendi reTextile neFiber Engineering yeIndia Institute of Technology, Delhi, akagadzira N9 yeblue nano sirivheri muna 2013, ine hunyanzvi hwekuteya nekuuraya mabhakitiriya kupfuura mamwe masimbi nemapolima. .Ikozvino, akaongorora maantiviral zvivakwa uye akagadziridza komisheni kurwisa COVID-19.Akataura kuti nyika zhinji, kusanganisira United States, China, neAustralia, dzakanyorera patents emhando dzakasiyana dzesirivheri (yero nebrown) kuti igadzirise kusarudzika kwesimbi maererano nehutsanana hwepamusoro."Zvisinei, N9 yebhuruu sirivha ine nguva yakareba yekudzivirira inoshanda, inogona kuwedzerwa nezana."
Masangano munyika yose (kunyanya IIT) ari mumatanho akasiyana ekugadzira aya nanoparticles semachira epamusoro.Pasati pave nemutemo uye zviri pamutemo kugadzirwa kwemazhinji, munhu wese akamirira kuti hutachiona huonekwe kuburikidza nemiedzo yemumunda.
Sezvineiwo, chitupa chinodiwa chinoda kupfuudza marabhoritari akatenderwa nehurumende (akadai seICMR, CSIR, NABL kana NIV), ayo parizvino ari kungopinda mutsvakurudzo yemishonga uye yekudzivirira.
Mamwe marabhoritari akazvimirira muIndia kana kunze kwenyika akatoedza zvimwe zvigadzirwa.Semuenzaniso, Germcop, kambani yekutanga-up iri muDelhi, yatanga kushandisa mvura-based antibacterial products yakagadzirwa muUnited States uye yakasimbiswa neEPA yemabasa ekuuraya utachiona.Chigadzirwa ichi chinonzi chakapfapfaidzwa pasimbi, isiri-simbi, mataira uye magirazi epamusoro kuti ape anosvika zana nemakumi maviri mumazuva gumi ekutanga.Kudzivirirwa kwezuva, uye ine mwero wekuuraya we99.9%.Muvambi Dr. Pankaj Goyal vakati chigadzirwa chakakodzera mhuri dzakazviparadzanisa nevarwere vane COVID-positive.Ari kutaura neDelhi Transport Company kuti abvise utachiona mabhazi chiuru.Nekudaro, bvunzo iyi yakaitwa murabhoritari yakazvimirira.
Iwo masampuli kubva kuIIT Delhi akatumirwa kuMSL microbiological yekuongorora marabhoritari muUK muna Kubvumbi.Mashoko aya anotarisirwa chete gore rino risati rapera.Muzvinafundo Agrawal akati: "Nhevedzano yebvunzo dzemurabhoritari inosimbisa kushanda kwekomboni munzvimbo yakaoma, kumhanya uye nguva yekuenderera mberi kwekuuraya hutachiona, uye kuti haina chepfu uye yakachengeteka kushandisa."
Kunyangwe Muzvinafundo Agrawal's N9 Blue Silver ari weNano Mission chirongwa chinotsigirwa neBazi reSainzi neTekinoroji yehurumende yeIndia, chimwe chirongwa chakatsigirwa neIIT Madras uye chakatsigirwa neNational Defense Research and Development Organisation chakagadzirirwa maPPE kits, masiki, uye vekutanga vekurapa vashandi.Magirovhosi anoshandiswa.Iyo yekuputira inosefa submicron huruva zvidimbu mumhepo.Nekudaro, iko kushanda kwayo chaiko kunofanirwa kuongororwa mumunda, saka inoda kugadziriswa.
Tinogona, asi nekufamba kwenguva, hazvisi sarudzo dzakanaka kwatiri kana zvakatipoteredza.Dr. Rohini Sridhar, Chief Operating Officer weApollo Hospital muMadurai, vakati kusvika pari zvino, mishonga inouraya utachiona inoshandiswa munzvimbo dzine vanhu vakawanda sezvipatara nemakiriniki dzine doro, phosphate kana hypochlorite solutions, izvo zvinowanzozivikanwa semumba bleach."Mishonga iyi inorasikirwa nebasa rayo nekuda kwekukurumidza kubuda uye kuora kana yakavhenekerwa nechiedza cheultraviolet (sezuva), izvo zvinoda kuuraya utachiona hwepamusoro kakawanda pazuva."
Zvinoenderana nekuwanikwa kwechikepe cheDiamond Princess cruise, coronavirus inogona kugara mazuva gumi nemanomwe pamusoro, saka tekinoroji nyowani yekuuraya hutachiona yabuda.Apo maantiviral coatings anga achiongororwa kukiriniki munyika dzinoverengeka, mwedzi mitatu yadarika, masayendisiti kubva kuHaifa Institute of Technology muIsrael akati akagadzira antiviral polima anogona kuuraya coronavirus pasina kuideredza.
Vatsvagiri vekuHong Kong University yeScience neTekinoroji vakagadzirawo nyowani antibacterial coating inonzi MAP-1, inogona kuuraya mabhakitiriya mazhinji nehutachiona-kusanganisira coronaviruses-kwemazuva anosvika makumi mapfumbamwe.
Muzvinafundo Agrawal vakati kubva pakaitika denda rekupedzisira reSARS, nyika zhinji dzave kushanda mukugadzira mapolymer anobata kupisa anopindura kubata kana kudonha kusvibiswa.Mazhinji eaya magadzirirwo akagadziridzwa panguva yedenda riripo uye anotengeswa pasi pemazita akasiyana emhando muJapan, Singapore neUnited States.Nekudaro, iwo ekudzivirira epamusoro anowanikwa pamusika wepasirese ari pinchable.
