Vatsvagiri vepaYunivhesiti yeCentral Florida vakagadzira nanoparticle-based disinfectant inogona kuramba ichiuraya hutachiona pamusoro kwemazuva anosvika manomwe - kuwanikwa kunogona kuve chombo chine simba kurwisa COVID-19 nemamwe mavhairasi ari kubuda epathogenic.
Tsvagiridzo iyi yakaburitswa svondo rino mujenari ACS Nano yeAmerican Chemical Society neboka rakasiyana-siyana rehutachiona uye nyanzvi dzeinjiniya kubva kuyunivhesiti uye mukuru wekambani yehunyanzvi muOrlando.
Mumazuva ekutanga edenda, Christina Drake, alumnus weUCF uye muvambi weKismet Technologies, akafemerwa mushure merwendo rwekuenda kuchitoro kunogadzira mishonga inouraya utachiona. Ikoko, akaona mushandi achimwaya mushonga wekuuraya utachiona pamubato wefiriji achibva angopukuta pafiriji.
"Pakutanga pfungwa yangu yaive yekugadzira mushonga wekuuraya hutachiona unokurumidza kuita," akadaro, "asi takataura nevatengi - vakadai savanachiremba nemazino - kuti vaone kuti ndeipi mushonga wekuuraya utachiona wavaida chaizvo. Kwavari Chinhu chinonyanya kukosha ndicho chinogara. Icharamba ichiuraya utachiona nzvimbo dzakanyanya kubata senge mibato yemagonhi uye pasi kwenguva yakareba mushure mekushandisa. ”
Dr. Nemari kubva kuNational Science Foundation, Kismet Tech, uye Florida High-Tech Corridor, vaongorori vakagadzira nanoparticle yakagadzira disinfectant.
Chinhu chayo chinoshanda injinjiniya nanostructure inonzi cerium oxide, inozivikanwa nokuda kwekugadzirisa kwayo antioxidant zvinhu. Cerium oxide nanoparticles inogadziridzwa nechidimbu chesirivheri kuti iite kuti inyatso kurwisa utachiona.
"Inoshanda mukemesitiri nemuchina," anotsanangura kudaro Seal, ave achidzidza nanotechnology kwemakore anopfuura 20. "Nanoparticles inoburitsa maerekitironi kuti iwedzere hutachiona uye husashande. Semichina, vanozvibatanidza nehutachiona uye vanobvarura pasi sebharumu rinoputika. "
Mazhinji ekuuraya utachiona anopukuta kana kupfapfaidza anozouraya hutachiona mukati memaminitsi matatu kusvika matanhatu mushure mekushandisa, asi hapana chakasara. Izvi zvinoreva kuti pamusoro pacho panofanirwa kupukutwa kakawanda kuti igare yakachena kudzivirira kutapukirwa nehutachiona hwakawanda hwakaita seCOVID-19. Iyo nanoparticle kuumbwa inochengetedza kugona kwayo kusaita tupukanana uye inoenderera mberi nekuuraya hutachiona hwepamusoro kwemazuva anosvika manomwe mushure mekushandisa kamwe chete.
"Madisinfectants anoratidza basa rakakura rekurwisa hutachiona hwehutachiona hunomwe hwakasiyana," Parks akatsanangura, uye marabhoritari yake ine basa rekuyedza kurwisa hutachiona "duramazwi". "Haina kungoratidza antiviral zvivakwa kurwisa coronavirus uye rhinoviruses, asi zvakare yakaratidza kuti inoshanda kurwisa mamwe mavhairasi akasiyana ane akasiyana zvimiro uye zvakaomarara. Tinovimba kuti nekugona kunoshamisa uku kwekuuraya, mushonga uyu wekuuraya utachiona uchavewo chishandiso chinoshanda kurwisa mamwe mavhairasi ari kubuda. "
Masayendisiti anotenda kuti mhinduro iyi ichange iine simba guru pahutano hwehutano, kunyanya kuderedza kuitika kwezvirwere zvinowanikwa muchipatara-zvakadai se methicillin-resistant Staphylococcus aureus (MRSA), Pseudomonas aeruginosa uye Clostridium difficile -Izvi zvichakonzera zvirwere zvinokanganisa kupfuura chikamu chimwe muzvitatu chevarwere vakapinzwa muzvipatara zveUS.
Kusiyana nemishonga yakawanda yekuuraya utachiona, iyi fomula haina makemikari anokuvadza, ayo anoratidza kuti akachengeteka kushandisa pane chero nzvimbo. Zvinoenderana nezvinodiwa neUS Environmental Protection Agency, bvunzo dzekudzora paganda uye kushatirwa kwesero reziso hakuna kuratidza kukuvadza.
"Mazhinji emishonga ekuuraya utachiona emumba aripo parizvino ane makemikari anokuvadza muviri mushure mekuratidzwa kakawanda," akadaro Drake. "Zvigadzirwa zvedu zvenanoparticle-based zvichave nepamusoro pekuchengetedza, izvo zvichaita basa rakakosha mukuderedza kuratidzwa kwevanhu kumakemikari."
Kutsvagisa kwakawanda kunodiwa zvigadzirwa zvisati zvapinda mumusika, ndosaka chikamu chinotevera chekutsvagisa chichatarisa pakuita kwemishonga inouraya utachiona mukushandisa zvinoshanda kunze kwerabhoritari. Iri basa richadzidza kuti mishonga yekuuraya utachiona inobatwa sei nezvinhu zvekunze senge tembiricha kana chiedza chezuva. Chikwata chiri munhaurirano nenetiweki yezvipatara zvemuno kuti vaedze chigadzirwa muzvivakwa zvavo.
Drake akawedzera kuti: "Tiri kuongororawo kugadzirwa kwefirimu rekare kuti tione kana tichikwanisa kuvhara nekuvhara pasi pechipatara kana mabatiro emagonhi, nzvimbo dzinoda kuuraya utachiona, kana kunyange nzvimbo dzinogara dzichisangana."
Seal akabatana neUCF's Dhipatimendi reZvinhu Sainzi neUinjiniya muna 1997, inova chikamu cheUCF Chikoro cheUinjiniya uye Computer Science. Anoshanda muchikoro chekurapa uye inhengo yeUCF prosthetic boka Biionix. Ndiye aimbova director weUCF Nano Science and Technology Center uye Advanced Materials Processing and Analysis Center. Akawana PhD muinjiniya yemidziyo kubva kuYunivhesiti yeWisconsin, aine mudiki mune biochemistry, uye muongorori wepashure paLawrence Berkeley National Laboratory paYunivhesiti yeCalifornia, Berkeley.
Mushure mekushanda paWake Forest School of Medicine kwemakore makumi maviri, Parkes akauya kuUCF mu2014, kwaakashanda sepurofesa uye mukuru weDhipatimendi reMicrobiology uye Immunology. Akagamuchira Ph.D. mune biochemistry kubva kuYunivhesiti yeWisconsin uye muongorori weAmerican Cancer Society kuNorthwestern University.
Tsvagiridzo iyi yakanyorwa pamwe naCandace Fox, muongorori wepashure kubva kuUCF Chikoro cheMishonga, Craig Neal kubva kuUCF Chikoro cheUinjiniya neComputer Science, uye vadzidzi vakapedza kudzidza Tamil Sakthivel, Udit Kumar, uye Yifei Fu kubva kuUCF Chikoro cheUinjiniya uye Computer Science. .
Zvishandiso zvinopihwa neYunivhesiti yeCentral Florida. Basa rekutanga rakanyorwa naChristine Senior. Cherechedza: Zviri mukati zvinogona kugadziriswa maererano nemaitiro uye urefu.
