"Magic material" graphene

"Magic material" graphene angagwiritsidwe ntchito pozindikira mwachangu komanso molondola za COVID-19
Malinga ndi malipoti atolankhani akunja, ofufuza ku Yunivesite ya Illinois ku Chicago adagwiritsa ntchito bwino graphene, imodzi mwazinthu zolimba komanso zowonda kwambiri zomwe zimadziwika, kuti azindikire kachilombo ka sars-cov-2 pakuyesa kwa labotale. Zomwe zapezazi zitha kukhala zopambana pakuzindikirika kwa COVID-19 ndipo zitha kugwiritsidwa ntchito polimbana ndi COVID-19 ndi mitundu yake, ofufuza akutero.
Poyesera, ofufuzawo adaphatikizanamapepala a grapheneyokhala ndi masitampu 1/1000 okha okhala ndi antibody opangidwa kuti alondole ma glycoprotein odziwika bwino pa COVID-19. Iwo ndiye anayeza kugwedezeka kwa atomiki kwa mapepala a graphene pamene adakumana ndi zitsanzo za cowid zabwino ndi cowid mu malovu opangira. Kugwedezeka kwa ma antibody ophatikizidwa ndi pepala la graphene kunasintha atathandizidwa ndi zitsanzo zabwino za cowid-19, koma sikunasinthe atathandizidwa ndi zitsanzo zoyipa za cowid-19 kapena ma coronavirus ena. Kusintha kwa kugwedezeka komwe kuyezedwa ndi chipangizo chotchedwa Raman spectrometer kumawonekera mphindi zisanu. Zomwe adapeza zidasindikizidwa mu ACS Nano pa Juni 15, 2021.
"Gulu likufunika njira zabwinoko zodziwira covid ndi mitundu yake mwachangu komanso molondola, ndipo kafukufukuyu ali ndi kuthekera kobweretsa kusintha kwenikweni. Sensa yotukuka imakhala ndi chidwi komanso kusankha bwino kwa covid, ndipo ndiyotsika mtengo komanso yotsika mtengo, adatero Vikas Berry, wolemba wamkulu wa pepalali" Thewapadera katunduya "magic material" graphene imapangitsa kuti ikhale yosunthika kwambiri, yomwe imapangitsa kuti mtundu uwu wa sensa utheke.
Graphene ndi mtundu wazinthu zatsopano zokhala ndi ma atomu a kaboni osakanizidwa a SP2 olumikizidwa mwamphamvu munsanjika imodzi yamitundu iwiri ya uchi. Ma atomu a carbon amalumikizidwa pamodzi ndi zomangira za mankhwala, ndipo kusinthasintha kwake ndi kuyenda kungapangitse kugwedezeka kwa resonance, komwe kumatchedwanso phonon, komwe kungayesedwe molondola kwambiri. Molekyulu ngati sars-cov-2 ikalumikizana ndi graphene, imasintha kugwedezeka kwa resonance m'njira yeniyeni komanso yowerengeka. Kugwiritsa ntchito kwa ma sensor atomiki a graphene - kuyambira pakuzindikirika kwa covid mpaka ALS mpaka khansa - kukupitilizabe kukula, ofufuza akutero.
