"Izinto zomlingo" i-graphene

I-graphene “yezinto zomlingo” ingasetshenziswa ukuthola ngokushesha nangokunembile i-COVID-19
Ngokusho kwemibiko yabezindaba bakwamanye amazwe, abacwaningi e-University of Illinois eChicago basebenzise ngempumelelo i-graphene, enye yezinto eziqine kakhulu nezincane kakhulu ezaziwayo, ukuthola igciwane le-sars-cov-2 ekuhlolweni kwelebhu. Lokhu okutholakele kungaba yintuthuko ekutholakaleni kwe-COVID-19 futhi kungasetshenziswa ekulweni ne-COVID-19 kanye nezinhlobo zayo, kusho abacwaningi.
Kulolu cwaningo, abacwaningi bahlanganiseamashidi e-grapheneenobukhulu obuyi-1/1000 kuphela yesitembu esine-antibody eyenzelwe ukubhekisisa ama-glycoprotein adumile ku-COVID-19. Base belinganisa ukudlidliza kwezinga le-athomu kwamaphepha e-graphene lapho evezwa kokubili amasampula e-cowid positive kanye ne-cowid negative ematheni okwenziwa. Ukudlidliza kweshidi le-graphene elihlanganiswe ne-antibody kwashintsha lapho kwelashwa ngamasampula amahle e-cowid-19, kodwa akuzange kushintshe lapho kwelashwa ngamasampula amabi e-cowid-19 noma amanye ama-coronavirus. Izinguquko zokudlidliza ezilinganiswa ngedivayisi ebizwa ngokuthi i-Raman spectrometer zisobala ngemizuzu emihlanu. Okutholakele kwabo kwanyatheliswa ku-ACS Nano ngoJuni 15, 2021.
"Kusobala ukuthi umphakathi udinga izindlela ezingcono zokuthola i-covid kanye nezinhlobo zayo ngokushesha nangokunembile, futhi lolu cwaningo lunamandla okuletha ushintsho lwangempela. Inzwa ethuthukisiwe inokuzwela okuphezulu nokukhetha i-covid, futhi iyashesha futhi ishibhile. USaid Vikas berry, umbhali omkhulu wephepha" I-Theizakhiwo eziyingqayizivelei-graphene “yezinto zomlingo” yenza kube lula kakhulu ukuyisebenzisa, okwenza lolu hlobo lwenzwa lube nokwenzeka.
I-Graphene uhlobo lwezinto ezintsha ezinama-athomu e-carbon axhunyiwe yi-SP2 hybrid ahlanganiswe ngokuqinile esakhiweni se-lattice se-honeycomb esinezingqimba ezimbili. Ama-athomu e-carbon ahlanganiswa ndawonye ngezibopho zamakhemikhali, futhi ukuqina kwawo kanye nokunyakaza kwawo kungadala ukudlidliza kwe-resonance, okwaziwa nangokuthi i-phonon, okungalinganiswa ngokunembe kakhulu. Lapho i-molecule efana ne-sars-cov-2 ixhumana ne-graphene, ishintsha lokhu kudlidliza kwe-resonance ngendlela ecacile kakhulu futhi elinganiswayo. Abacwaningi bathi ukusetshenziswa okungenzeka kwezinzwa ze-graphene atomic scale - kusukela ekutholeni i-covid kuya ku-ALS kuya kumdlavuza - kuyaqhubeka nokukhula, kusho abacwaningi.
