UCF alum thiab ntau tus kws tshawb fawb tau siv nanotechnology los tsim cov tshuaj ntxuav no, uas tuaj yeem tiv taus xya tus kab mob mus txog 7 hnub.
Cov kws tshawb fawb UCF tau tsim cov tshuaj tua kab mob nanoparticle uas tuaj yeem tua cov kab mob txuas ntxiv mus txog 7 hnub-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.
Christina Drake '07PhD, tus tsim ntawm Kismet Technologies, tau txais kev tshoov siab los ntawm kev mus rau lub khw muag khoom noj thaum pib muaj kev sib kis thiab 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.
Dr. Greif Parks, tus kws kho mob virologist ntawm Tsev Kawm Ntawv Tshuaj, tau tsim cov tshuaj tua kab mob hauv kev koom tes nrog cov kws tsim khoom thiab cov neeg ua lag luam. Duab qhov chaw: University of Central Florida
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 nkag siab tias cov tshuaj tua kab mob twg lawv xav tau tiag tiag. Qhov tseem ceeb tshaj plaws rau lawv yog Nws yog qhov siv tau ntev, nws yuav txuas ntxiv tshuaj tua kab mob siab rau thaj chaw sib cuag xws li lub qhov rooj thiab hauv pem teb rau lub sijhawm ntev tom qab thov. "
Drake koom tes nrog Sudipta Seal, UCF cov ntaub ntawv engineer thiab nanoscience kws tshaj lij, thiab Griff Parks, tus kws kho mob virologist, kws tshawb fawb tus thawj coj ntawm Tsev Kawm Ntawv Tshuaj, thiab tus thawj coj 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.
Sudipta Seal yog UCF cov ntaub ntawv engineer thiab nanoscience kws tshaj lij uas tau kawm txog nanotechnology rau 20 xyoo dhau los. Duab qhov chaw: University of Central Florida
"Nws ua haujlwm hauv chemistry thiab mechanics," said 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 tawg, ib yam li tawg lub zais pa. "
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.
"Cov tshuaj tua kab mob no qhia tau hais tias muaj kev tiv thaiv kab mob zoo tiv thaiv xya tus kab mob sib txawv," said Parks, uas nws lub chaw soj nstuam yog lub luag haujlwm rau kev ntsuas tus qauv tiv thaiv tus kab mob "dictionary". "Nws tsis tsuas yog qhia txog cov tshuaj tiv thaiv kab mob tiv thaiv tus mob coronaviruses thiab rhinoviruses, tab sis kuj ua pov thawj tias nws muaj txiaj ntsig zoo tiv thaiv ntau yam kab mob nrog cov qauv sib txawv thiab qhov 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 kev kis kab mob hauv tsev kho mob, xws li methicillin-resistant Staphylococcus aureus (MRSA), Pseudomonas aeruginosa thiab Clostridium difficile —— Lawv cuam tshuam ntau dua ib ntawm 30. cov neeg mob tau mus rau hauv tsev kho mob 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.
"Peb tseem tab tom tshawb nrhiav kev txhim kho cov yeeb yaj kiab ib nrab mus tas li kom pom tias peb tuaj yeem npog thiab kaw cov tsev kho mob hauv tsev lossis lub qhov rooj tuav, thaj chaw uas yuav tsum tau tshuaj tua kab mob, lossis txawm tias thaj chaw muaj kev sib cuag thiab txuas mus ntxiv," Drake tau hais.

Lawv yuav tsum tsuas yog siv cov nyiaj colloidal thiab tsis yog lwm yam tsis tseeb. Nws yuav zoo dua tawm tsam txhua yam kab mob phem thiab tsis xav tau PhD lossis ntau lab ntawm hype thiab raug cai. nkaus xwb. Nws tsis tuaj yeem ua yam tsis muaj patents.
Peb muaj tus neeg saib xyuas kev tiv thaiv uas tuaj yeem khaws cov khoom siv tshuaj tua kab mob ntev txog 90 hnub thiab ua kom cov chaw mos muag tshuaj tua kab mob thoob plaws lub neej ntawm cov khoom. Nws muaj nyob rau ntau xyoo. Peb tau ua lag luam txij li xyoo 1978. Peb tsis yog Covid cowboys uas nyuam qhuav tshwm sim thaum Lub Peb Hlis 2020. Yog xav paub ntxiv, thov hu rau DSG Industrial Cleaning Systems hauv Kansas City, Missouri.
Colloidal nyiaj ua haujlwm los ntawm kev nres lub voj voog kev tsim tawm. Tsis muaj kev tiv thaiv. Nws yuav tsum tau siv dav hauv txhua qhov chaw. Kuv xav kom nws kuj nres MERSA. Kuv pom zoo tag nrho ntawm txhua yam uas tuaj yeem txhim kho nyiaj. Lwm qhov ua tau yog txhaj cov tub rog-qib superabsorbent nrog tshem tawm cov nyiaj. Cov khoom zoo li no yuav tsum muaj txiaj ntsig zoo.
