Graphene "Ibikoresho by'ubumaji"

Graphene "ibikoresho by'ubumaji" ishobora gukoreshwa mu gutahura COVID-19 byihuse kandi neza
Nk’uko byatangajwe n’itangazamakuru ryo mu mahanga, abashakashatsi bo muri Kaminuza ya Illinois i Chicago bakoresheje neza graphene, kimwe mu bikoresho bikomeye kandi byoroheje bizwi, kugira ngo bamenye virusi ya sars-cov-2 mu igerageza rya laboratwari. Abashakashatsi bavuga ko ibyavuye mu bushakashatsi bishobora kuba intambwe ikomeye mu gupima COVID-19 kandi bishobora gukoreshwa mu kurwanya COVID-19 n’ubwoko bwayo.
Muri iryo gerageza, abashakashatsi bahujeimpapuro za grapheneifite ubunini bwa 1/1000 gusa hamwe n’umuti urwanya indwara wagenewe kwibasira glycoproteins zizwi cyane kuri COVID-19. Hanyuma bapimye imitingito y’urwego rwa atome rw’impapuro za graphene ubwo zahuraga n’ibipimo bya cowid positive na cowid negative mu macandwe y’ubukorano. Imitingito y’impapuro za graphene zifatanye n’umuti urwanya indwara ya cowid-19 yarahindutse iyo yavuwe n’ibipimo bya cowid-19, ariko ntiyahindutse iyo yavuwe n’ibipimo bya cowid-19 cyangwa izindi coronavirus. Impinduka mu mitingito zapimwe hakoreshejwe igikoresho cyitwa Raman spectrometer ziragaragara mu minota itanu. Ibyo bavumbuye byasohotse muri ACS Nano ku ya 15 Kamena 2021.
“Nta gushidikanya ko umuryango ukeneye uburyo bwiza bwo kumenya covid n’uburyo igaragara vuba kandi neza, kandi ubu bushakashatsi bufite ubushobozi bwo kuzana impinduka nyazo. Sensor nziza ifite ubushobozi bwo kumenya no guhitamo covid cyane, kandi ni yihuse kandi ihendutse Said Vikas berry, umwanditsi mukuru w’iyi nyandiko“ Theimitungo idasanzweGraphene y' "ibikoresho by'ubumaji" ituma ikoreshwa mu buryo butandukanye cyane, ibi bigatuma ubwo bwoko bwa sensor bushoboka.
Graphene ni ubwoko bw'ibikoresho bishya bifite atome za karuboni zihujwe na SP2 hybrid zifatanye neza mu buryo bw'urukuta rw'ubuki rufite urwego rumwe rw'ibice bibiri. Atome za karuboni zihuzwa hamwe n'imigozi ya shimi, kandi ubwiyongere bwazo n'ingendo yazo bishobora gutuma habaho guhindagura kw'isura, bizwi kandi nka phonon, bishobora gupimwa neza cyane. Iyo molekile nka sars-cov-2 ikorana na graphene, ihindura uku guhindagura kw'isura mu buryo bwihariye kandi bushobora gupimwa. Abashakashatsi bavuga ko ikoreshwa ry'ibikoresho bya graphene atomic scale sensors - kuva ku kumenya covid kugeza kuri ALS kugeza kuri kanseri - rikomeje kwiyongera.
