I-graphene “yezinto zomlingo” ingasetshenziselwa ukutholwa ngokushesha nangokunembile kwe-COVID-19
Ngokwemibiko yabezindaba yakwamanye amazwe, abacwaningi baseNyuvesi yase-Illinois e-Chicago basebenzise ngempumelelo i-graphene, enye yezinto eziqine kakhulu nezincane kakhulu ezaziwayo, ukuthola igciwane le-sars-cov-2 ekuhlolweni kwaselabhorethri. Okutholakele kungase kube impumelelo ekutholakaleni kwe-COVID-19 futhi kungase kusetshenziswe ekulweni ne-COVID-19 nezinhlobonhlobo zayo, kusho abacwaningi.
Ekuhlolweni, abacwaningi bahlangeneamashidi e-grapheneenogqinsi lwezitembu eziyi-1/1000 kuphela ezine-antibody eklanyelwe ukukhomba ama-glycoprotein adume kabi ku-COVID-19. Babe sebelinganisa ukudlidliza kweleveli ye-athomu yamashidi e-graphene lapho evezwe kukho kokubili amasampula e-cowid positive kanye ne-cowid negative kumathe okwenziwa. Ukudlidliza kweshidi le-graphene elihlanganiswe ne-antibody kushintshile lapho kuphathwa ngamasampula amahle e-cowid-19, kodwa akuzange kushintshe lapho kuphathwa ngamasampuli angemahle e-cowid-19 noma amanye ama-coronavirus. Izinguquko zokudlidliza zikalwa ngedivayisi ebizwa nge-Raman spectrometer ziyabonakala emizuzwini emihlanu. Okutholakele kwabo kushicilelwe ku-ACS Nano ngoJuni 15, 2021.
“Umphakathi udinga ngokusobala izindlela ezingcono zokuthola i-covid kanye nezinhlobonhlobo zayo ngokushesha nangokunembile, futhi lolu cwaningo lunamandla okuletha ushintsho lwangempela. Inzwa ethuthukisiwe inokuzwela okuphezulu nokukhetha ku-covid, futhi ibiza ngokushesha futhi iphansi kusho i-Vikas berry, umbhali ophezulu wephepha.izakhiwo eziyingqayizivele"yezinto zomlingo" i-graphene iyenza ibe nezinto ezihlukahlukene kakhulu, okwenza lolu hlobo lwenzwa lube khona.
I-Graphene iwuhlobo lwento entsha enama-athomu ekhabhoni ayi-SP2 axhumeke ngokuqinile afakwe ungqimba olulodwa olunezinhlangothi ezimbili. Ama-athomu ekhabhoni ahlanganiswe ndawonye ngamabhondi amakhemikhali, futhi ukunwebeka nokunyakaza kwawo kungaveza ukundindizela kwe-resonance, okubuye kwaziwe ngokuthi i-phonon, engalinganiswa ngokunembile kakhulu. Uma i-molecule efana ne-sars-cov-2 isebenzisana ne-graphene, ishintsha lokhu kudlidliza kwe-resonance ngendlela ecacile nelinganisekayo. Ukusetshenziswa okungaba khona kwezinzwa ze-graphene atomic scale - kusuka ekutholeni i-covid kuya ku-ALS kuya kumdlavuza - kuyaqhubeka nokukhula, kusho abacwaningi.
