"Magic material" graphene e ka sebelisoa ho lemoha COVID-19 ka potlako le ka nepo
Ho latela litlaleho tsa mecha ea litaba ea kantle ho naha, bafuputsi Univesithing ea Illinois e Chicago ba atlehile ho sebelisa graphene, e leng e 'ngoe ea lisebelisoa tse matla le tse tšesaane tse tsejoang, ho bona vaerase ea sars-cov-2 litekong tsa laboratori. Liphuputso e kanna ea ba katleho ea ho fumanoa ha COVID-19 mme li ka sebelisoa ho loants'a COVID-19 le mefuta ea eona, bafuputsi ba re.
Tekong, bafuputsi ba ile ba kopanyamaqephe a graphenee nang le botenya ba litempe tse 1/1000 feela tse nang le antibody e etselitsoeng ho shebana le li-glycoprotein tse tummeng hampe ho COVID-19. Eaba ba lekanya ho sisinyeha ha boemo ba athomo ba maqephe a graphene ha ba ne ba pepesehetse lisampole tse mpe tsa cowid le tse mpe tsa cowid matheng a maiketsetso. Ho sisinyeha ha pampiri ea graphene ea antibody e ile ea fetoha ha e phekoloa ka lisampole tse ntle tsa cowid-19, empa ha ea ka ea fetoha ha e tšoaroa ka lisampole tse mpe tsa cowid-19 kapa li-coronavirus tse ling. Liphetoho tsa vibrate tse lekantsoeng ka sesebelisoa se bitsoang Raman spectrometer li bonahala ka mor'a metsotso e mehlano. Liphuputso tsa bona li phatlalalitsoe ho ACS Nano ka la 15 Phuptjane 2021.
"Sechaba se hloka ka ho hlaka mekhoa e betere ea ho bona covid le mefuta ea eona kapele le ka nepo, 'me thuto ena e na le monyetla oa ho tlisa phetoho ea nnete. Sensor e ntlafalitsoeng e na le kutlo e phahameng le khetho ea ho khetha covid, 'me e potlakile ebile e theko e tlase ho boletse Vikas berry, sengoli se phahameng sa pampiri" Thethepa e ikhethangea "magic material" graphene e etsa hore e feto-fetohe haholo, e leng se etsang hore mofuta ona oa kutlo o khonehe.
Graphene ke mofuta oa thepa e ncha e nang le liathomo tsa khabone tse nyalisitsoeng tsa SP2 tse kentsoeng ka thata ka har'a moaho o le mong oa khekhe ea linotši ea mahlakore a mabeli. Liathomo tsa carbon li tlamahanngoa hammoho ke lik’hemik’hale tse kopanyang lik’hemik’hale, ’me ho tsitsa ha tsona le ho sisinyeha ha tsona ho ka hlahisa ho sisinyeha ha resonance, ho tsejoang hape e le phonon, e ka lekanngoang ka nepo haholo. Ha molek'hule e kang sars-cov-2 e sebelisana le graphene, e fetola li-vibrations tsena tsa resonance ka tsela e hlakileng haholo le e hlakileng. Lisebelisoa tse ka bang teng tsa li-sensor tsa graphene atomic scale - ho tloha ho fumanoa ha covid ho ea ho ALS ho isa mofetšeng - li ntse li tsoela pele ho hola, bafuputsi ba re.
