A UCF alum uye vaongorori vakati wandei vakashandisa nanotechnology kugadzira iyi yekuchenesa, inogona kuramba mavhairasi manomwe kwemazuva manomwe.
Vatsvagiri veUCF vakagadzira nanoparticle-based disinfectant inogona kuramba ichiuraya mavhairasi pamusoro kwemazuva anosvika manomwe - kuwanikwa uku 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.
Christina Drake '07PhD, muvambi weKismet Technologies, akafemerwa nerwendo rwekuenda kuchitoro chegirosari pakutanga kwedenda uye akagadzira mushonga wekuuraya hutachiona. 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 vakaita savanachiremba nemazino kuti vanzwisise kuti ndeipi mushonga wekuuraya utachiona wavanoda chaizvo. Chinonyanya kukosha kwavari chinhu chinogara kwenguva refu, chicharamba chichiuraya nzvimbo dzepamusoro dzakadai sezvibato zvegonhi uye pasi kwenguva yakareba mushure mekushandisa. "
Drake anoshanda naSudipta Seal, injiniya yeUCF uye nyanzvi yesainzi, naGriff Parks, chiremba wehutachiona, dhipatimendi wekutsvagisa weChikoro cheMishonga, uye mukuru weBurnett Chikoro cheBiomedical Sayenzi. Nemari kubva kuNational Science Foundation, Kismet Tech, uye Florida High-Tech Corridor, vatsvakurudzi vakagadzira nanoparticle engineered 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 mune zvese chemistry nemuchina," akadaro Seal, anga achidzidza nanotechnology kwemakore anopfuura makumi maviri. "Nanoparticles inoburitsa maerekitironi kuti iwedzere hutachiona uye husashande. Nemichina, vanozvibatanidza nehutachiona uye vanobvarura pasi, sekunge kuputika kwebharumu. "
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.
"Mushonga wekuuraya utachiona uyu unoratidza basa rakakura rekurwisa hutachiona hwehutachiona hunomwe hwakasiyana," akadaro Parks, ane marabhoritari ane basa rekuyedza kurwisa hutachiona "duramazwi". "Iyo haingoratidzi antiviral zvivakwa kurwisa coronavirus uye rhinoviruses, asi zvakare inoratidza kuti inoshanda kurwisa akasiyana emamwe mavhairasi 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 ichave nekukanganisa kwakakosha nharaunda yehutano, kunyanya kuderedza kuitika kwezvirwere zvinowanikwa muchipatara, senge methicillin-resistant Staphylococcus aureus (MRSA), Pseudomonas aeruginosa neClostridium difficile—— Zvinokanganisa zvinopfuura chimwe mu30 varwere vakagamuchirwa kuzvipatara zveAmerica.
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.
"Tiri kuongororawo kuvandudzwa kwefirimu rekare kuti tione kana tichikwanisa kuvhara uye kuvhara pasi pechipatara kana zvibatiso zvemusuwo, nzvimbo dzinoda kuuraya utachiona, kana kunyange nzvimbo dzinoshanda uye dzinoenderera mberi," Drake akadaro.
Seal akabatana neUCF's Dhipatimendi reZvinhu Sainzi neUinjiniya muna 1997, inova chikamu cheUCF Chikoro cheUinjiniya uye Computer Science. Prosthesis. 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.
Chidzidzo ichi chakanyorwa pamwe chete naCandace Fox, muongorori wepashure muChikoro cheMishonga, uye Craig Neal kubva kuChikoro cheUinjiniya uye Computer Science. Tamil Sakthivel, Udit Kumar, uye Yifei Fu, vadzidzi vakapedza kudzidza paChikoro cheUinjiniya neComputer Science, zvakare vanyori-vamwe.
