"Izinto zomlingo" igraphene

“Izinto zomlingo” igraphene inokusetyenziselwa ukuchongwa ngokukhawuleza nangokuchanekileyo kwe-COVID-19
Ngokweengxelo zemithombo yeendaba zangaphandle, abaphandi kwiYunivesithi yase-Illinois eChicago basebenzise ngempumelelo igraphene, enye yezona zinto zinamandla kunye nezona zincinci zaziwayo, ukufumanisa intsholongwane ye-sars-cov-2 kuvavanyo lwaselabhoratri. Iziphumo zinokuba yinkqubela phambili ekubhaqweni kwe-COVID-19 kwaye inokusetyenziswa kumlo ochasene ne-COVID-19 kunye nokwahluka kwayo, abaphandi bathi.
Kuvavanyo, abaphandi badibanisaamaphepha egrapheneezinobunzima bezitampu eziyi-1/1000 kuphela ezine-antibody eyilelwe ukujolisa notorious repute glycoproteins kwi-COVID-19. Baye ke balinganisa inqanaba lokungcangcazela kweatom yamaphepha egraphene xa bevezwe kuzo zombini iisampulu ezine-cowid positive kunye ne-cowid negative kumathe okwenziwa. Ukungcangcazela kwe-antibody edityaniswe nephepha legraphene latshintsha xa kunyangwa iisampulu ezilungileyo ze-cowid-19, kodwa ayizange itshintshe xa iphathwa ngeesampulu ezimbi ze-cowid-19 okanye ezinye ii-coronavirus. Utshintsho lokungcangcazela olulinganiswa ngesixhobo esibizwa ngokuba yiRaman spectrometer luyabonakala kwimizuzu emihlanu. Iziphumo zabo zapapashwa kwi-ACS Nano ngoJuni 15, 2021.
"Uluntu lufuna ngokucacileyo iindlela ezingcono zokufumanisa i-covid kunye nokwahluka kwayo ngokukhawuleza nangokuchanekileyo, kwaye olu phononongo lunamandla okuzisa utshintsho lokwenyani. Inzwa ephuculweyo inovelwano oluphezulu kunye nokukhetha kwi-covid, kwaye iyakhawuleza kwaye inexabiso eliphantsi utshilo uVikas berry, umbhali ophezulu wephepha.iimpawu ezizodwa"yezinto zomlingo" igraphene iyenza ibe nezinto ezininzi ezahlukeneyo, nto leyo eyenza olu hlobo lwesivamvo lwenzeke.
IGraphene luhlobo lwemathiriyeli entsha ene-SP2 hybrid edityaniswe iiathom zekhabhoni ezipakishwe ngokuqinileyo kwi-single-layer ene-dimensional two-dimensional lettice lattice structure. Iiathom zekhabhon zidityaniswe kunye ngamabhondi ekhemikhali, kwaye ukunwebeka kwazo kunye nokushukuma kwazo kunokuvelisa i-resonance vibration, ekwabizwa ngokuba yiphonon, enokulinganiswa ngokuchanekileyo kakhulu. Xa imolekyuli efana ne-sars-cov-2 inxibelelana negraphene, iyayitshintsha le ntshukumo yeresonance ngendlela ecacileyo nenokulinganiswa. Ukusetyenziswa okunokubakho kwe-graphene atomic sensors scale - ukusuka ekubhaqweni kwe-covid ukuya kwi-ALS ukuya kumhlaza - kuyaqhubeka ukwanda, abaphandi bathi.
