15kii toddobaad ee la soo dhaafay, immisa jeer ayaad dusha jeermiska ku tirtirtay si waali ah?Sababta cabsida COVID-19 ayaa keentay saynisyahano inay daraasad ku sameeyaan alaabada ku saleysan nanotechnology, adeegsiga dhowr atom.Waxay raadinayaan xal loogu talagalay dahaarka dusha sare ee ku xidhi kara alaabta oo ilaalin kara bakteeriyada (bakteeriyada, fayrasyada, fungi, protozoa) muddo dheer.
Waa polymers isticmaala biraha (sida qalinka iyo naxaasta) ama biomolecules (sida soosaarayaasha immem ee loo yaqaan waxqabadkooda microbial) ama cationic (ie si togan loo dallaco) polymers leh isticmaalka muddada-dheer ee xeryahooda kiimikada (sida ammonia iyo nitrogen).) Dahaarka ilaalinta walxaha loo isticmaalo isku-darka.Xarunta waxaa lagu buufin karaa birta, dhalooyinka, alwaax, dhagax, dhar, maqaar iyo walxo kale, saameyntu waxay socotaa hal usbuuc ilaa 90 maalmood, iyadoo ku xiran nooca dusha loo isticmaalo.
Faafida ka hor, waxaa jiray alaabo jeermis-dileyaal ah, laakiin hadda diiradda ayaa loo rogay fayrasyada.Tusaale ahaan, Professor Ashwini Kumar Agrawal, oo madax ka ah Waaxda Injineerka Dharka iyo Fiber Engineering ee Machadka Teknolojiyadda Hindiya, Delhi, wuxuu sameeyay N9 buluug nano qalin ah 2013, kaasoo awood aad u sarreeya u leh inuu dabinno oo dilo bakteeriyada marka loo eego biraha iyo polymers kale. .Hadda, wuxuu qiimeeyay guryaha ka hortagga fayraska wuxuuna dib u habeyn ku sameeyay xarunta si loola dagaallamo COVID-19.Waxa uu sheegay in dalal badan, oo ay ku jiraan Maraykanka, Shiinaha, iyo Australia, ay codsadeen patents noocyada kala duwan ee qalin (jaalle iyo brown) si loo ogaado gaar ah ee birta ee dhinaca nadaafadda dusha."Si kastaba ha ahaatee, N9 qalin buluug ah ayaa leh wakhtiga ilaalinta ugu waxtarka badan, kaas oo lagu kordhin karo 100 jeer."
Machadyada dalka oo dhan (gaar ahaan IIT) waxay ku jiraan heerar kala duwan oo ay ku horumarinayaan nanoparticles sida dahaarka dusha sare.Kahor soo saarista tirada guud ee sharciga iyo sharciga ah, qof kastaa wuxuu sugayaa in fayraska lagu xaqiijiyo tijaabooyin gudaha ah.
Fikrad ahaan, shahaadada loo baahan yahay waxay u baahan tahay inay ku gudubto shaybaarada ay dawladdu ogolaatay (sida ICMR, CSIR, NABL ama NIV), kuwaas oo hadda ku hawlan oo kaliya cilmi-baarista daroogada iyo tallaalka.
Qaar ka mid ah shaybaarada gaarka loo leeyahay ee Hindiya ama dibadda ayaa mar hore tijaabiyay alaabada qaarkood.Tusaale ahaan, Germcop, oo ah shirkad bilow ah oo ku taal Delhi, waxay bilowday inay isticmaasho badeecooyinka bakteeriyada biyaha ku salaysan ee lagu sameeyay Maraykanka oo ay shahaado EPA u siisay adeegyada jeermiska.Alaabta ayaa la sheegay in lagu buufiyo biraha, kuwa aan birta ahayn, tile iyo dusha muraayadaha si loo helo ilaa 120 10 maalmood ee ugu horreeya.Ilaalinta maalinta, oo leh heerka dilaaga 99.9%.Aasaasaha Dr. Pankaj Goyal wuxuu sheegay in alaabtu ay ku habboon tahay qoysaska go'doomiyey bukaannada qaba COVID-positive.Waxay kala hadlaysaa Shirkadda Gaadiidka Delhi inay jeermiska ka saarto 1,000 bas.Si kastaba ha ahaatee, baaritaanka waxaa lagu sameeyay shaybaar gaar ah.
Shaybaarada IIT Delhi waxaa loo diray shaybaadhka baadhista microbiological MSL ee UK bishii Abriil.Warbixinnadan ayaa la filayaa ka hor dhammaadka sanadkan.Professor Agrawal wuxuu yiri: "Tijaabooyin shaybaar oo taxane ah ayaa xaqiijin doona waxtarka xarunta xaalad qalalan, xawaaraha iyo muddada sii socoshada dilka fayraska, iyo haddii aysan ahayn mid sun ah oo ammaan ah in la isticmaalo."
In kasta oo Professor Agrawal's N9 Blue Silver uu iska leeyahay mashruuca Nano Mission ee ay maalgelisay Wasaaradda Sayniska iyo Tignoolajiyada ee dawladda Hindiya, mashruuc kale oo ay maalgelisay IIT Madras oo ay maalgelisay Ururka Cilmi-baarista iyo Horumarinta Difaaca Qaranka ayaa loo sameeyay qalabyada PPE, waji-xidhka, iyo shaqaalaha caafimaadka ee safka hore.galoofyada la isticmaalo.Dahaarka ayaa shaandheeya qaybaha boodhka submicron ee hawada ku jira.Si kastaba ha ahaatee, codsigeeda dhabta ah waa in la mariyaa tijaabada goobta, markaa waxay u baahan tahay in la xalliyo.
Waan awoodnaa, laakiin mustaqbalka fog, maahan doorashooyin caafimaad qaba anaga iyo deegaankaba.Dr. Rohini Sridhar, oo ah madaxa hawlgelinta ee cisbitaalka Apollo ee Madurai, ayaa sheegay in ilaa hadda, jeermis-dileyaasha caadiga ah ee lagu isticmaalo meelaha dadku ku badan yahay sida isbitaallada iyo rugaha caafimaadka ay ka kooban yihiin alkohol, fosfat ama hypochlorite xalal, kuwaas oo inta badan loo yaqaanno biliijka guriga."Xallalkani waxay luminayaan shaqadooda sababtoo ah uumiga degdega ah waxayna qurmayaan marka ay la kulmaan iftiinka ultraviolet (sida qorraxda), taas oo u baahan in jeermi-dilista dusha sare ee dhowr jeer maalintii."
Marka loo eego helitaanka markabka dheeman Princess, coronavirus-ku wuxuu sii jiri karaa ilaa 17 maalmood oogada sare, markaa tignoolajiyad cusub oo jeermiska ayaa soo baxday.Markii daaha ka-hortagga fayraska ay ku socdeen baaris caafimaad dalal dhowr ah, saddex bilood ka hor, saynisyahano ka socda Machadka Teknolojiyadda Haifa ee Israa'iil waxay sheegteen inay sameeyeen polymers-ka-hortagga fayraska oo dili kara coronavirus-ka iyada oo aan la dhimin.
Cilmi-baarayaal ka tirsan jaamacadda Hong Kong ee Sayniska iyo Teknolojiyadda ayaa sidoo kale sameeyay daahan cusub oo bakteeriyada bakteeriyada loo yaqaan MAP-1, kaas oo dili kara bakteeriyada iyo fayrasyada badankood-oo ay ku jiraan coronaviruses-ilaa 90 maalmood.
Professor Agrawal wuxuu sheegay in tan iyo markii ugu dambeysay ee faafitaanka SARS, dalal badan ay ka shaqeynayeen sidii ay u horumarin lahaayeen polymers-kuleelka kuwaas oo ka jawaabaya wasakhowga taabashada ama dhibicda.Qaar badan oo ka mid ah qaababkan ayaa wax laga beddelay intii lagu jiray aafada hadda jirta waxaana lagu iibiyaa magacyo summadeed oo kala duwan oo ku yaal Japan, Singapore iyo Mareykanka.Si kastaba ha ahaatee, wakiilada ilaalinta dusha sare ee hadda laga heli karo suuqa caalamiga ah waa la qanjaruufo.
*Qorshahayagu isdiiwaangelinta dhijitaalka ah hadda kuma jiraan waraaqo elektaroonik ah, xujooyin is-dhaafsi ah, iPhone, iPad apps mobile iyo agab daabacan.Qorshahayagu wuxuu wanaajin karaa khibradaada akhriska.
Xiliyadan adag waxaan idin soo gudbinaynay xogtii ugu danbeeysay ee ku saabsan isbadalada ka jira India iyo aduunka kuwaaso si dhow ula xiriira caafimaadkeena iyo fayoobideena, nolosheena iyo maciishadaba.Si aan u baahinno wararka danta guud ku jira, waxaanu kordhinay qoraalada wax akhriska xorta ah, waxaanu kordhinay mudada tijaabada xorta ah.Si kastaba ha ahaatee, waxaan u haynaa shuruudo isticmaalayaasha isdiiwaangelin kara: fadlan sidaas samee.In kasta oo aan la macaamilno macluumaadka beenta ah iyo macluumaadka beenta ah oo aan la soconno waqtiyada, waxaan u baahanahay inaan dhaqaale badan gelino hawlaha ururinta wararka.Waxaa naga go’an inaan bixino warar tayo sare leh oo aan saameyn ku yeelan dano gaar ah iyo dacaayad siyaasadeed.
Taageerada aad u haysaan saxafiyiinta waa mid aad u qiimo badan.Tani waa taageerada saxaafadda ee runta iyo xaqa.Waxay naga caawisaa inaan la jaanqaadno waqtiyada.
Hinduuga ayaa had iyo jeer u taagan saxaafadda danaha guud.Waqtigan adag, helitaanka macluumaadka si dhow ula xiriira caafimaadkeena iyo fayoqabkeena, nolosheena iyo nolosheena ayaa noqonaysa mid aad muhiim u ah.Macmiil ahaan, ma tihid kaliya ka faa'iidaystaha shaqadeena, laakiin sidoo kale dhiirrigeliyeheeda.
Waxaan sidoo kale halkan ku celinaynaa in kooxdayada suxufiyiinta, nuqul-qorayaasha, xaqiiqooyinka hubinta, naqshadeeyayaasha iyo sawir qaadayaashu ay dammaanad qaadi doonaan inay bixiyaan warar tayo sare leh iyagoon keenin dano gaar ah iyo dacaayad siyaasadeed.
