"Thepa ea boselamose" graphene

Graphene ea "boselamose" e ka sebelisoa bakeng sa ho lemoha COVID-19 ka potlako le ka nepo
Ho ea ka litlaleho tsa mecha ea litaba ea kantle ho naha, bafuputsi Univesithing ea Illinois e Chicago ba atlehile ho sebelisa graphene, e 'ngoe ea lisebelisoa tse matla le tse tšesaane ka ho fetisisa tse tsejoang, ho lemoha vaerase ea sars-cov-2 litekong tsa laboratori. Bafuputsi ba re liphuputso tsena e ka ba tsoelo-pele ho fumanoeng ha COVID-19 'me li ka sebelisoa ntoeng khahlanong le COVID-19 le mefuta ea eona.
Tekong ena, bafuputsi ba kopantsemaqephe 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 thothomela ha maemo a athomo a maqephe a graphene ha ba pepesetsoa lisampole tse ntle tsa cowid le cowid tse mpe matheng a maiketsetso. Ho thothomela ha leqephe la graphene le kopantsoeng le antibody ho ile ha fetoha ha ho phekoloa ka lisampole tse ntle tsa cowid-19, empa ha hoa ka ha fetoha ha ho phekoloa ka lisampole tse mpe tsa cowid-19 kapa li-coronavirus tse ling. Liphetoho tsa ho thothomela tse lekantsoeng ka sesebelisoa se bitsoang Raman spectrometer lia totobala ka metsotso e mehlano. Liphuputso tsa bona li phatlalalitsoe ho ACS Nano ka la 15 Phuptjane, 2021.
"Ho hlakile hore sechaba se hloka mekhoa e betere ea ho lemoha covid le mefuta ea eona kapele le ka nepo, 'me phuputso ena e na le bokhoni ba ho tlisa phetoho ea 'nete. Sensor e ntlafalitsoeng e na le kutloelo-bohloko e phahameng le khetho ho covid, 'me e potlakile ebile e theko e tlase. Said Vikas berry, mongoli e moholo oa pampiri" Thethepa e ikhethangea "thepa ea boselamose" graphene e etsa hore e be le mekhoa e mengata haholo, e leng se etsang hore mofuta ona oa sensor o khonehe.
Graphene ke mofuta oa thepa e ncha e nang le liathomo tsa khabone tse kopantsoeng tsa SP2 hybrid tse kopantsoeng ka thata ka har'a sebopeho sa lera le le leng la mahe a linotši a mahlakore a mabeli. Liathomo tsa khabone li kopantsoe hammoho ka litlamo tsa lik'hemik'hale, 'me ho tenyetseha ha tsona le motsamao li ka hlahisa ho thothomela ha resonance, e 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 ho thothomela hona ha resonance ka tsela e ikhethang haholo le e ka baloang. Bafuputsi ba re lits'ebetso tse ka bang teng tsa li-sensor tsa tekanyo ea athomo ea graphene - ho tloha ho fumaneng covid ho ea ho ALS ho ea ho kankere - li ntse li tsoela pele ho atoloha, ho bolela bafuputsi.
