"Zinthu zamatsenga" graphene

Graphene ya "zinthu zamatsenga" ingagwiritsidwe ntchito pozindikira mwachangu komanso molondola COVID-19
Malinga ndi malipoti a atolankhani akunja, ofufuza ku yunivesite ya Illinois ku Chicago agwiritsa ntchito bwino graphene, imodzi mwa zipangizo zolimba komanso zoonda kwambiri zodziwika, kuti azindikire kachilombo ka sars-cov-2 mu kafukufuku wa labotale. Zomwe zapezekazi zitha kukhala chitukuko chachikulu pakuzindikira COVID-19 ndipo zitha kugwiritsidwa ntchito polimbana ndi COVID-19 ndi mitundu yake, ofufuza akutero.
Mu kafukufukuyu, ofufuzawo adaphatikizamapepala a grapheneyokhala ndi makulidwe a 1/1000 stamps yokha yokhala ndi antibody yopangidwira kuthana ndi ma glycoprotein odziwika bwino pa COVID-19. Kenako anayeza kugwedezeka kwa ma atomu a mapepala a graphene pamene adakumana ndi zitsanzo za cowid positive ndi cowid negative m'malovu opangidwa. Kugwedezeka kwa pepala la graphene lolumikizidwa ndi antibody kunasintha pamene kunapatsidwa zitsanzo zabwino za cowid-19, koma sikunasinthe pamene kunapatsidwa zitsanzo zoipa za cowid-19 kapena ma coronavirus ena. Kusintha kwa kugwedezeka komwe kunayesedwa ndi chipangizo chotchedwa Raman spectrometer kumawonekera pakatha mphindi zisanu. Zomwe adapeza zidasindikizidwa mu ACS Nano pa June 15, 2021.
"Anthu akufunikira njira zabwino zodziwira covid ndi mitundu yake mwachangu komanso molondola, ndipo kafukufukuyu ali ndi kuthekera kobweretsa kusintha kwenikweni. Sensor yokonzedwa bwino ili ndi kuthekera kwakukulu kozindikira covid, ndipo ndi yachangu komanso yotsika mtengo Said Vikas berry, wolemba wamkulu wa pepalali" Thekatundu wapaderaChifukwa cha "zinthu zamatsenga" graphene, imapangitsa kuti ikhale yosinthasintha kwambiri, zomwe zimapangitsa kuti sensa yamtunduwu ikhale yotheka.
Graphene ndi mtundu wa zinthu zatsopano zokhala ndi maatomu a kaboni olumikizidwa ndi SP2 hybrid omwe amamangiriridwa mwamphamvu mu kapangidwe kake ka uchi wa magawo awiri. Maatomu a kaboni amalumikizidwa pamodzi ndi ma bond a mankhwala, ndipo kusinthasintha kwawo ndi kuyenda kwawo kumatha kupanga kugwedezeka kwa resonance, komwe kumadziwikanso kuti phonon, komwe kumatha kuyezedwa molondola kwambiri. Pamene molekyulu ngati sars-cov-2 imagwirizana ndi graphene, imasintha kugwedezeka kwa resonance m'njira yeniyeni komanso yowerengeka. Ofufuza akutero kuti kugwiritsa ntchito kwa graphene atomic scale sensors - kuyambira kuzindikira covid mpaka ALS mpaka khansa - kukupitilira kukula, akutero.
