M'masabata 15 apitawa, ndi kangati mudapukuta pamwamba ndi mankhwala ophera tizilombo mopupuluma?Choopsa cha COVID-19 chapangitsa asayansi kuphunzira zinthu zochokera ku nanotechnology, kugwiritsa ntchito maatomu ochepa.Akuyang'ana njira yothetsera zokutira pamwamba zomwe zingagwirizane ndi zipangizo ndikuteteza mabakiteriya (mabakiteriya, mavairasi, bowa, protozoa) kwa nthawi yaitali.
Ndi ma polima omwe amagwiritsa ntchito zitsulo (monga siliva ndi mkuwa) kapena ma biomolecules (monga zotulutsa za immem zomwe zimadziwika ndi zochita zawo zazing'ono) kapena ma polima a cationic (oyimitsidwa bwino) omwe amagwiritsa ntchito mankhwala kwanthawi yayitali (monga ammonia ndi nayitrogeni).) Zotchingira zoteteza zakuthupi zomwe zimagwiritsidwa ntchito kuphatikiza.Pawiri akhoza sprayed pa zitsulo, galasi, matabwa, mwala, nsalu, zikopa ndi zipangizo zina, ndipo zotsatira kumatenga sabata imodzi kwa masiku 90, malingana ndi mtundu wa pamwamba ntchito.
Mliri usanachitike, panali mankhwala oletsa mabakiteriya, koma tsopano chidwi chasinthira ku ma virus.Mwachitsanzo, Pulofesa Ashwini Kumar Agrawal, wamkulu wa dipatimenti ya Textile and Fiber Engineering ku Indian Institute of Technology, Delhi, anapanga N9 blue nano silver mu 2013, yomwe ili ndi luso lapamwamba kwambiri logwira ndi kupha mabakiteriya kuposa zitsulo zina ndi ma polima. .Tsopano, adawunikanso mphamvu za antiviral ndikukonzanso gululo kuti amenyane ndi COVID-19.Ananenanso kuti mayiko ambiri, kuphatikizapo United States, China, ndi Australia, apempha ma patent amitundu yosiyanasiyana ya siliva (yachikasu ndi yofiirira) kuti akhazikitse zachilendo zachitsulo pankhani yaukhondo."Komabe, siliva wa N9 wabuluu uli ndi nthawi yayitali kwambiri yoteteza, yomwe imatha kuonjezedwa nthawi 100."
Mabungwe m'dziko lonselo (makamaka IIT) ali mu magawo osiyanasiyana opanga ma nanoparticles ngati zokutira pamwamba.Asanapangidwe mwalamulo komanso mwalamulo, aliyense akuyembekezera kuti kachilomboka katsimikizidwe kudzera m'mayesero am'munda.
Moyenera, chiphaso chofunikira chikuyenera kudutsa malo ovomerezeka ovomerezeka ndi boma (monga ICMR, CSIR, NABL kapena NIV), omwe pakali pano amangochita kafukufuku wamankhwala ndi katemera.
Ma laboratories ena achinsinsi ku India kapena kunja adayesa kale zinthu zina.Mwachitsanzo, Germcop, kampani yoyambira yomwe ili ku Delhi, yayamba kugwiritsa ntchito mankhwala oletsa mabakiteriya opangidwa ndi madzi opangidwa ku United States ndikuvomerezedwa ndi EPA pantchito zopha tizilombo.Mankhwalawa akuti amapopera pazitsulo, zopanda zitsulo, matailosi ndi galasi kuti apereke 120 m'masiku 10 oyambirira.Chitetezo cha tsiku, ndipo ali ndi chiwopsezo cha kupha 99.9%.Woyambitsa Dr. Pankaj Goyal adati mankhwalawa ndi oyenera mabanja omwe adzipatula odwala omwe ali ndi COVID.Amalankhula ndi Delhi Transport Company kuti aphe mabasi 1,000.Komabe, kuyezetsako kwachitika mu labotale yapadera.
Zitsanzo zochokera ku IIT Delhi zidatumizidwa ku labotale yoyesa ma microbiological ya MSL ku UK mu Epulo.Malipotiwa akuyembekezeredwa kuti chaka chino chisanathe.Pulofesa Agrawal adati: "Mayeso angapo a labotale atsimikizira kuti ntchitoyi ikugwira ntchito pamalo owuma, kuthamanga komanso kutalika kwa kupha kachilomboka, komanso ngati ilibe poizoni komanso yotetezeka kugwiritsa ntchito."
Ngakhale Pulofesa Agrawal wa N9 Blue Silver ndi wa projekiti ya Nano Mission yothandizidwa ndi Unduna wa Sayansi ndi Ukadaulo wa boma la India, pulojekiti ina yothandizidwa ndi IIT Madras komanso yothandizidwa ndi National Defense Research and Development Organisation yapangidwira zida za PPE, masks, ndi ogwira ntchito zachipatala oyamba.Magolovesi ogwiritsidwa ntchito.Chophimbacho chimasefa tinthu tating'onoting'ono tomwe timakhala mumlengalenga.Komabe, ntchito yake yeniyeni iyenera kuyesedwa m'munda, chifukwa chake iyenera kuthetsedwa.
Titha, koma m'kupita kwanthawi, sizosankha zabwino kwa ife kapena chilengedwe.Dr. Rohini Sridhar, Chief Operating Officer wa Apollo Hospital ku Madurai, adanena kuti mpaka pano, mankhwala ophera tizilombo toyambitsa matenda omwe amagwiritsidwa ntchito m'malo opezeka anthu ambiri monga zipatala ndi zipatala ali ndi mowa, phosphate kapena hypochlorite solutions, zomwe nthawi zambiri Zimadziwika kuti bleach yapakhomo."Mayankho awa amasiya kugwira ntchito chifukwa cha nthunzi mwachangu komanso kuwola akakhala ndi kuwala kwa ultraviolet (monga dzuwa), zomwe zimapangitsa kuti padziko lapansi pakhale tizilombo toyambitsa matenda kangapo patsiku."
Malinga ndi kupezeka kwa sitima yapamadzi ya Diamond Princess, coronavirus imatha kukhala masiku 17 pamtunda, kotero ukadaulo watsopano wopha tizilombo watulukira.Pamene zokutira zolimbana ndi ma virus zikuyesedwa m'maiko angapo, miyezi itatu yapitayo, asayansi ochokera ku Haifa Institute of Technology ku Israel adati adapanga ma polima oletsa ma virus omwe amatha kupha coronavirus popanda kuchepetsa.
Ofufuza ku Hong Kong University of Science and Technology apanganso zokutira zatsopano zotchedwa MAP-1, zomwe zimatha kupha mabakiteriya ambiri ndi ma virus-kuphatikiza ma coronaviruses-kwa masiku 90.
Pulofesa Agrawal adati kuyambira mliri womaliza wa SARS, mayiko ambiri akhala akugwira ntchito yopanga ma polima osamva kutentha omwe amayankha kukhudza kapena kuipitsa madontho.Zambiri mwazinthuzi zasinthidwa panthawi ya mliri wapano ndipo zimagulitsidwa pansi pa mayina osiyanasiyana ku Japan, Singapore ndi United States.Komabe, zoteteza pamwamba zomwe zikupezeka pamsika wapadziko lonse lapansi ndizotsina.
*Dongosolo lathu lolembetsa pa digito pakadali pano silimaphatikizirapo e-paper, puzzles, iPhone, mapulogalamu am'manja a iPad ndi zida zosindikizidwa.Dongosolo lathu likhoza kukulitsa luso lanu lowerenga.
Munthawi zovuta zino, takhala tikukupatsirani zidziwitso zaposachedwa zokhudzana ndi zomwe zikuchitika ku India ndi dziko lapansi, zomwe zikugwirizana kwambiri ndi thanzi lathu, moyo wathu komanso moyo wathu.Pofuna kufalitsa nkhani zomwe zili zokomera anthu, tawonjezera kuchuluka kwa zolemba zaulere ndikuwonjezera nthawi yoyeserera kwaulere.Komabe, tili ndi zofunikira kwa ogwiritsa ntchito omwe angalembetse: chonde teroni.Ngakhale kuti timalimbana ndi nkhani zabodza komanso zabodza komanso tikuyenda ndi nthawi, tifunika kuyika ndalama zambiri posonkhanitsa nkhani.Ndife odzipereka kupereka nkhani zapamwamba popanda kukhudzidwa ndi zofuna zathu komanso mabodza andale.
Thandizo lanu pa utolankhani wathu ndilofunika kwambiri.Uku ndikuthandizira kwa atolankhani pazowona ndi chilungamo.Zimatithandiza kuyenderana ndi nthawi.
Chihindu nthawi zonse chimayimira utolankhani mokomera anthu.Panthawi yovutayi, kupeza chidziwitso chomwe chikugwirizana kwambiri ndi thanzi lathu ndi thanzi lathu, miyoyo yathu ndi moyo wathu zimakhala zofunika kwambiri.Monga olembetsa, simungopindula ndi ntchito yathu, komanso woyilimbikitsa.
Tikubwerezanso apa kuti gulu lathu la atolankhani, olemba makope, ofufuza zenizeni, okonza mapulani ndi ojambula azitsimikizira kuti apereka nkhani zapamwamba kwambiri popanda kuyambitsa zokonda zawo komanso mabodza andale.
