Cov kws tshawb fawb ntawm University of Central Florida tau tsim cov tshuaj tua kab mob nanoparticle uas tuaj yeem tua cov kab mob txuas ntxiv mus txog 7 hnub - qhov kev tshawb pom uas yuav dhau los ua riam phom muaj zog tiv thaiv COVID-19 thiab lwm yam kab mob tshwm sim.
Cov kev tshawb fawb tau luam tawm lub lim tiam no hauv phau ntawv xov xwm ACS Nano ntawm American Chemical Society los ntawm ntau pab neeg ntawm cov kab mob thiab cov kws tshaj lij engineering los ntawm lub tsev kawm ntawv thiab tus thawj coj ntawm lub tuam txhab thev naus laus zis hauv Orlando.
Thaum ntxov ntawm kev kis tus kabmob kis thoob ntiaj teb, Christina Drake, tus kws qhia ntawv UCF thiab tus tsim ntawm Kismet Technologies, tau txais kev tshoov siab tom qab taug kev mus rau lub khw muag khoom noj los tsim cov tshuaj tua kab mob. Nyob ntawd, nws pom ib tug neeg ua hauj lwm txau tshuaj tua kab mob ntawm lub tub yees thiab ces tam sim ntawd so cov tshuaj tsuag.
Nws tau hais tias "Thaum pib kuv lub tswv yim yog los tsim cov tshuaj tua kab mob sai," tab sis peb tau tham nrog cov neeg siv khoom - xws li kws kho mob thiab kws kho hniav - kom paub seb cov tshuaj tua kab mob twg lawv xav tau tiag tiag. Rau lawv Qhov tseem ceeb tshaj plaws yog qhov uas kav ntev. Nws yuav txuas ntxiv tshuaj tua kab mob rau thaj chaw siab xws li lub qhov rooj thiab cov plag tsev rau lub sijhawm ntev tom qab thov. "
Drake tau koom tes nrog Dr. Sudipta Seal, UCF cov ntaub ntawv engineer thiab nanoscience kws tshaj lij, thiab Dr. Griff Parks, tus kws kho mob virologist, kws tshawb fawb tus thawj coj ntawm Tsev Kawm Ntawv Tshuaj, thiab Dean ntawm Burnett Tsev Kawm Ntawv ntawm Biomedical Sciences. Nrog kev pab nyiaj los ntawm National Science Foundation, Kismet Tech, thiab Florida High-Tech Corridor, cov kws tshawb fawb tau tsim cov tshuaj tua kab mob nanoparticle.
Nws cov khoom xyaw nquag yog ib qho kev tsim qauv nanostructure hu ua cerium oxide, paub txog nws cov khoom siv tshuaj tua kab mob antioxidant. Cerium oxide nanoparticles tau hloov kho nrog cov nyiaj me me kom ua rau lawv zoo dua tiv thaiv kab mob.
"Nws ua haujlwm hauv chemistry thiab tshuab," piav qhia Seal, uas tau kawm txog nanotechnology rau ntau tshaj 20 xyoo. “Nanoparticles emit electrons los oxidize tus kab mob thiab ua rau nws inactive. Mechanically, lawv kuj txuas lawv tus kheej mus rau tus kab mob thiab ua rau lub ntsej muag zoo li lub zais pa tawg. "
Feem ntau cov tshuaj tua kab mob los yog tshuaj tsuag yuav tshuaj tua kab mob hauv qhov chaw tsis pub dhau peb mus rau rau feeb tom qab siv, tab sis tsis muaj qhov seem seem. Qhov no txhais tau hais tias qhov saum npoo yuav tsum tau muab rov qab ua kom nws huv si kom tsis txhob kis tau ntau yam kab mob xws li COVID-19. Cov txheej txheem nanoparticle tswj nws lub peev xwm los ua kom tsis muaj kab mob thiab txuas ntxiv tua cov kab mob mus txog 7 hnub tom qab ib daim ntawv thov.
Parks piav qhia tias "Cov tshuaj tua kab mob ua kom pom cov tshuaj tiv thaiv kab mob zoo heev tiv thaiv xya tus kab mob," Parks piav qhia, thiab nws lub chaw kuaj mob yog lub luag haujlwm rau kev sim cov tshuaj tiv thaiv tus kab mob "dictionary". "Nws tsis tsuas yog pom cov tshuaj tiv thaiv kab mob tiv thaiv tus mob coronaviruses thiab rhinoviruses, tab sis kuj tau ua pov thawj tias muaj txiaj ntsig zoo tiv thaiv ntau yam kab mob nrog cov qauv sib txawv thiab nyuaj. Peb cia siab tias muaj peev xwm tua tau zoo, cov tshuaj tua kab mob no kuj tseem yuav dhau los ua cov cuab yeej siv tau zoo tiv thaiv lwm cov kab mob tshwm sim. "
Cov kws tshawb fawb ntseeg tias qhov kev daws teeb meem no yuav muaj kev cuam tshuam loj rau kev noj qab haus huv ib puag ncig, tshwj xeeb tshaj yog txo qhov tshwm sim ntawm cov kab mob hauv tsev kho mob-xws li methicillin-resistant Staphylococcus aureus (MRSA), Pseudomonas aeruginosa thiab Clostridium difficile -Cov no yuav ua rau cov kab mob uas cuam tshuam ntau dua. ib feem peb ntawm cov neeg mob tau mus rau hauv tsev kho mob hauv Asmeskas.
Tsis zoo li ntau cov tshuaj tua kab mob hauv kev lag luam, cov mis no tsis muaj cov tshuaj phem, uas qhia tau tias nws muaj kev nyab xeeb siv rau txhua qhov chaw. Raws li qhov yuav tsum tau ua ntawm US Environmental Protection Agency, kev tswj xyuas ntawm daim tawv nqaij thiab qhov muag ntawm tes tsis pom muaj teeb meem.
Drake tau hais tias "Muaj ntau yam tshuaj tua kab mob hauv tsev tam sim no muaj cov tshuaj uas tsim kev puas tsuaj rau lub cev tom qab kis tau dua," Drake tau hais. "Peb cov khoom siv nanoparticle-raws li yuav muaj kev nyab xeeb siab, uas yuav ua lub luag haujlwm tseem ceeb hauv kev txo tag nrho tib neeg raug tshuaj lom neeg."
Kev tshawb fawb ntxiv yog xav tau ua ntej cov khoom nkag mus rau hauv kev ua lag luam, yog vim li cas cov theem tom ntej ntawm kev tshawb fawb yuav tsom mus rau kev ua haujlwm ntawm cov tshuaj tua kab mob hauv kev siv tswv yim sab nraum lub chaw soj nstuam. Txoj haujlwm no yuav kawm seb cov tshuaj tua kab mob cuam tshuam li cas los ntawm lwm yam xws li kub lossis hnub ci. Pab neeg no tab tom tham nrog lub tsev kho mob hauv zos network los sim cov khoom hauv lawv cov chaw.
Drake tau hais ntxiv tias: "Peb tseem tab tom tshawb nrhiav kev tsim cov yeeb yaj kiab ib nrab mus tas li kom pom tias peb tuaj yeem npog thiab kaw cov plag tsev hauv tsev kho mob lossis lub qhov rooj tuav, thaj chaw uas yuav tsum tau tshuaj tua kab mob, lossis txawm tias thaj chaw uas muaj kev sib cuag thiab tsis tu ncua."
Seal tau koom nrog UCF lub Department of Materials Science thiab Engineering hauv 1997, uas yog ib feem ntawm UCF Tsev Kawm Ntawv ntawm Engineering thiab Computer Science. Nws ua haujlwm hauv tsev kawm ntawv kho mob thiab yog ib tus tswv cuab ntawm UCF prosthetic pab pawg Biionix. Nws yog yav dhau los tus thawj coj ntawm UCF Nano Science thiab Technology Center thiab Advanced Materials Processing and Analysis Center. Nws tau txais PhD hauv cov khoom siv engineering los ntawm University of Wisconsin, nrog me me hauv biochemistry, thiab yog tus kws tshawb fawb tom qab ntawm Lawrence Berkeley National Laboratory ntawm University of California, Berkeley.
Tom qab ua haujlwm ntawm Wake Forest School of Medicine rau 20 xyoo, Parkes tuaj rau UCF hauv 2014, uas nws tau ua tus xibfwb thiab tus thawj coj ntawm Lub Tsev Haujlwm Saib Xyuas Kev Noj Qab Haus Huv thiab Tshuaj Tiv Thaiv. Nws tau txais Ph.D. hauv biochemistry los ntawm University of Wisconsin thiab yog tus kws tshawb fawb ntawm American Cancer Society ntawm Northwestern University.
Cov kev tshawb fawb tau sau los ntawm Candace Fox, tus kws tshawb fawb tom qab UCF Tsev Kawm Ntawv Tshuaj, Craig Neal los ntawm UCF Lub Tsev Kawm Ntawv ntawm Engineering thiab Computer Science, thiab cov tub ntxhais kawm tiav Tamil Sakthivel, Udit Kumar, thiab Yifei Fu los ntawm UCF Tsev Kawm Ntawv ntawm Engineering thiab Computer Science .
