Graphene

Graphene “Magic material” irashobora gukoreshwa mugutahura vuba kandi neza COVID-19
Nk’uko ibitangazamakuru byo mu mahanga bibitangaza, abashakashatsi bo muri kaminuza ya Illinois i Chicago bakoresheje neza graphene, kimwe mu bikoresho bikomeye kandi binini cyane bizwi, kugira ngo bamenye virusi ya sars-cov-2 mu bushakashatsi bwa laboratoire. Abashakashatsi bavuga ko ibyavuye mu bushakashatsi bishobora kuba intambwe mu gutahura COVID-19 kandi bishobora gukoreshwa mu kurwanya COVID-19 n'ibindi bitandukanye.
Mu bushakashatsi, abashakashatsi bahurije hamweurupapuro rwa graphenehamwe nubunini bwa kashe ya 1/1000 gusa hamwe na antibody yagenewe kwibasira glycoproteine ​​izwi cyane kuri COVID-19. Bahise bapima urwego rwa atome rwinyeganyeza rwimpapuro za graphene mugihe bahuye nicyitegererezo cyiza cyinka hamwe ninka mbi mumacandwe yubukorikori. Kunyeganyega kwa antibody bifatanye na graphene urupapuro rwahindutse iyo bivuwe hamwe nicyitegererezo cyiza cya cowid-19, ariko nticyahindutse mugihe cyakorewe ingero mbi za cowid-19 cyangwa izindi coronavirus. Impinduka zinyeganyeza zapimwe nigikoresho cyitwa Raman spectrometer kiragaragara muminota itanu. Ibyavuye mu bushakashatsi byatangajwe muri ACS Nano ku ya 15 Kamena 2021.
Ati: "Sosiyete ikeneye uburyo bwiza bwo kumenya covid nibihinduka byihuse kandi neza, kandi ubu bushakashatsi bufite ubushobozi bwo kuzana impinduka nyazo. Sensor yatezimbere ifite sensibilité nyinshi kandi ihitamo covid, kandi irihuta kandi ihendutse Said Vikas berry, umwanditsi mukuru wimpapuro “Theibintu byihariyeya "magic material" graphene ituma ihinduka cyane, ituma ubu bwoko bwa sensor bushoboka.
Graphene ni ubwoko bwibintu bishya hamwe na SP2 ya Hybrid ihujwe na karubone ya karubone yapakiwe neza murwego rumwe rwibice bibiri byubuki bwubuki. Atome ya karubone ihujwe nububiko bwa shimi, kandi ubworoherane bwayo nigikorwa cyayo birashobora kubyara vibrance vibrasion, izwi kandi nka fonon, ishobora gupimwa neza. Iyo molekile nka sars-cov-2 ikorana na graphene, ihindura ibyo bihindagurika bya resonance muburyo bwihariye kandi bugereranywa. Abashakashatsi bavuga ko uburyo bushobora gukoreshwa bwa graphene atomike yerekana urugero - kuva gutahura covid kugeza ALS kugeza kanseri - bikomeje kwaguka.
