Ua hoʻomohala nā mea noiʻi ma ke Kulanui o Central Florida i kahi disinfectant e pili ana i ka nanoparticle e hiki ke hoʻomau i ka pepehi ʻana i nā maʻi ma ka ʻili a hiki i 7 mau lā - kahi ʻike e lilo i mea kaua ikaika e kūʻē iā COVID-19 a me nā maʻi maʻi pathogenic e kū mai ana.
Ua paʻi ʻia ka noiʻi i kēia pule ma ka puke pai ʻo ACS Nano o ka American Chemical Society e kahi hui multidisciplinary o nā virus a me nā loea loea mai ke kulanui a me ke poʻo o kahi hui ʻenehana ma Orlando.
I nā lā mua o ka maʻi maʻi, ua hoʻoikaika ʻia ʻo Christina Drake, kahi haumāna UCF a me ka mea hoʻokumu o Kismet Technologies, ma hope o kahi huakaʻi i ka hale kūʻai e hoʻomohala i nā disinfectants. Ma laila, ʻike ʻo ia i kahi limahana e pīpī ana i ka disinfectant ma luna o ka pahu friji a laila holoi koke i ka ʻehu.
"I ka wā mua, ʻo koʻu manaʻo e hoʻomohala i kahi disinfectant wikiwiki," i ʻōlelo ai ʻo ia, "akā ua kamaʻilio mākou me nā mea kūʻai aku - e like me nā kauka a me nā niho niho - e ʻike i ka disinfectant a lākou i makemake ai. No lākou ʻO ka mea nui ka mea mau loa. E hoʻomau ia i ka disinfect i nā wahi pili kiʻekiʻe e like me nā lima puka a me nā papahele no ka manawa lōʻihi ma hope o ka noi.
Ua hui pū ʻo Drake me Dr. Sudipta Seal, he mea ʻenekinia mea UCF a me ka loea nanoscience, a me Kauka Griff Parks, he virologist, hoa noiʻi dean o ke Kula Lapaʻau, a me Dean o ka Burnett School of Biomedical Science. Me ke kālā mai ka National Science Foundation, Kismet Tech, a me ka Florida High-Tech Corridor, ua hana nā mea noiʻi i kahi disinfectant nanoparticle engineered.
ʻO kāna mea hana he nanostructure engineered i kapa ʻia ʻo cerium oxide, i ʻike ʻia no kāna mau waiwai antioxidant regenerative. Hoʻololi ʻia nā nanoparticles Cerium oxide me kahi kālā liʻiliʻi i mea e ʻoi aku ka maikaʻi o nā pathogens.
"Ke hana nei ia ma ka kemika a me ka mīkini," wehewehe ʻo Seal, ka mea i aʻo i ka nanotechnology no nā makahiki he 20. "Hoʻopuka nā nanoparticles i nā electrons e hoʻoneʻe i ka maʻi a hana ʻole ia. Ma ka mīkini, hoʻopili pū lākou iā lākou iho i ka maʻi maʻi a uhaʻi i ka ʻili e like me ka baluna pahū.
ʻO ka hapa nui o nā holoi disinfectant a i ʻole nā ʻōpala e disinfect i ka ʻili i loko o ʻekolu a ʻeono mau minuke ma hope o ka hoʻohana ʻana, akā ʻaʻohe hopena i koe. ʻO ia ke kumu e holoi pinepine ʻia ka ʻili i ka maʻemaʻe e pale aku i ka maʻi me nā maʻi he nui e like me COVID-19. Mālama ka nanoparticle formulation i kona hiki ke hoʻopau i nā microorganism a hoʻomau i ka disinfect i ka ʻili a hiki i 7 mau lā ma hope o kahi noi hoʻokahi.
"Hōʻike nā disinfectants i ka hana antiviral maikaʻi e kūʻē i ʻehiku mau maʻi maʻi like ʻole," wehewehe ʻo Parks, a ʻo kāna keʻena keʻena ke kuleana no ka hoʻāʻo ʻana i ke kūʻē ʻana o ka huaʻōlelo i ka huaʻōlelo "palapalapala". "ʻAʻole ia i hōʻike wale i nā waiwai antiviral e kūʻē i nā coronaviruses a me nā rhinoviruses, akā ua hōʻike pū ʻia hoʻi i ka hopena e kūʻē i nā maʻi like ʻole me nā ʻano like ʻole a me nā paʻakikī. Manaʻo mākou me kēia mana kupaianaha e pepehi, e lilo kēia disinfectant i mea hana pono loa e kūʻē i nā maʻi ʻē aʻe.
Manaʻo nā kānaka ʻepekema he hopena koʻikoʻi kēia hopena i ka nohona olakino, ʻoi aku ka hōʻemi ʻana i ka nui o nā maʻi i loaʻa i ka haukapila-e like me ka methicillin-resistant Staphylococcus aureus (MRSA), Pseudomonas aeruginosa a me Clostridium difficile - ʻO kēia ka mea e hoʻoulu ai i nā maʻi e pili ana i nā maʻi ʻoi aku ma mua o hoʻokahi hapakolu o nā maʻi i hoʻokomo i nā haukapila US.
ʻAʻole like me nā disinfectants pāʻoihana, ʻaʻole i loaʻa i kēia ʻano nā mea kemika pōʻino, e hōʻike ana he palekana ia e hoʻohana ma luna o kekahi ʻili. E like me nā koi o ka US Environmental Protection Agency, ʻaʻole i hōʻike ʻia nā hoʻokolohua hoʻoponopono i ka ʻili a me ka huhū o ka maka.
"ʻO ka hapa nui o nā disinfectants o ka hale i loaʻa i kēia manawa i nā kemika i hōʻino i ke kino ma hope o ka hoʻolaha pinepine ʻana," wahi a Drake. "ʻO kā mākou mau huahana nanoparticle e loaʻa i kahi kiʻekiʻe o ka palekana, kahi e hana nui ai i ka hōʻemi ʻana i ka ʻike kanaka āpau i nā kemika."
Pono ka noiʻi hou aʻe ma mua o ke komo ʻana o nā huahana i ka mākeke, ʻo ia ke kumu e nānā ai ka pae aʻe o ka noiʻi i ka hana o nā disinfectants i nā noi kūpono ma waho o ka hale hana. E aʻo ana kēia hana i ka hopena o nā disinfectants e nā mea o waho e like me ka mahana a i ʻole ka lā. Ke kamaʻilio nei ka hui me ka pūnaewele haukapila kūloko e hoʻāʻo i ka huahana i kā lākou mau hale.
Ua hoʻohui ʻo Drake: "Ke ʻimi nei mākou i ka hoʻomohala ʻana i kahi kiʻiʻoniʻoni semi-permanent e ʻike inā hiki iā mākou ke uhi a hoʻopaʻa i nā papahele o ka haukapila a i ʻole nā lima puka, nā wahi e pono ai ke hoʻomaʻemaʻe ʻia, a i ʻole nā wahi e hoʻomau mau nei i ka pilina."
Ua komo ʻo Seal i ke Keʻena ʻepekema a me ʻenekinia o UCF i ka makahiki 1997, he ʻāpana ia o ke kula ʻo UCF o ka ʻenekinia a me ka ʻepekema kamepiula. Ke lawelawe nei ʻo ia ma ke kula olakino a he lālā ʻo ia o ka hui prosthetic UCF Biionix. ʻO ia ka luna mua o ka UCF Nano Science and Technology Center a Advanced Materials Processing and Analysis Center. Ua loaʻa iā ia kahi PhD i ka ʻenekinia waiwai mai ke Kulanui o Wisconsin, me kahi keiki liʻiliʻi i ka biochemistry, a he mea noiʻi postdoctoral ma Lawrence Berkeley National Laboratory ma ke Kulanui o Kaleponi, Berkeley.
Ma hope o kāna hana ʻana ma ke kula ʻo Wake Forest School of Medicine no 20 mau makahiki, ua hele ʻo Parkes i UCF ma 2014, kahi i lawelawe ai ʻo ia ma ke ʻano he polopeka a me ke poʻo o ke Keʻena ʻo Microbiology a me Immunology. Ua loaʻa iā ia kahi Ph.D. i ka biochemistry mai ke Kulanui o Wisconsin a he mea noiʻi ia o ka American Cancer Society ma Northwestern University.
Ua kākau pū ʻia ka noiʻi e Candace Fox, he mea noiʻi postdoctoral mai UCF School of Medicine, Craig Neal mai UCF School of Engineering and Computer Science, a me nā haumāna puka kula Tamil Sakthivel, Udit Kumar, a me Yifei Fu mai UCF School of Engineering and Computer Science. .
Nā mea i hāʻawi ʻia e ke Kulanui o Central Florida. Na Christine Senior ka hana kumu. Nānā: Hiki ke hoʻoponopono ʻia ka ʻike e like me ke ʻano a me ka lōʻihi.
E kiʻi i ka nūhou ʻepekema hou loa ma o ka leka uila manuahi a ScienceDaily, i hōʻano hou ʻia i kēlā me kēia lā a me kēlā me kēia pule. A i ʻole e nānā i ka hānai nūhou hou i kēlā me kēia hola i kāu mea heluhelu RSS:
E haʻi mai iā mākou i kou manaʻo no ScienceDaily-aloha mākou i nā manaʻo maikaʻi a maikaʻi ʻole. Aia kekahi pilikia i ka hoʻohana ʻana i kēia pūnaewele? pilikia?
