"Magic material" graphene inogona kushandiswa kukurumidza uye kunyatsoona COVID-19
Zvinoenderana nemishumo yenhau dzekunze, vaongorori vepaYunivhesiti yeI Illinois kuChicago vakabudirira kushandisa graphene, chimwe chezvinhu zvakasimba uye zvakatetepa zvinozivikanwa, kuona hutachiona hwesars-cov-2 mukuyedza murabhoritari. Zvakawanikwa zvinogona kunge zviri budiriro mukuonekwa kweCCIDID-19 uye inogona kushandiswa mukurwisa COVID-19 uye akasiyana ayo, vanoongorora vanodaro.
Mukuedza, vatsvakurudzi vakabatanidzagraphene mapepaine hukobvu hwematampu 1/1000 chete ane antibody yakagadzirirwa kunanga notorious repute glycoproteins paCOVID-19. Vakabva vapima maatomic level vibrations of the graphene sheets pavakaratidzwa kune ese cowid positive necowid negative samples mumate ekugadzira. Kudengenyeka kweantibody yakasanganiswa graphene sheet yakachinja payakabatwa nemasampuli akanaka ecowid-19, asi haina kuchinja payakabatwa nemasamples asina kunaka ecowid-19 kana mamwe maconavirus. Shanduko dzekudengenyeka dzakayerwa nemudziyo unonzi Raman spectrometer dziri pachena mumaminetsi mashanu. Zvavakawana zvakaburitswa mu ACS Nano muna Chikumi 15, 2021.
"Sosaiti inoda zvirinani nzira dzekuona covid nemhando dzayo nekukurumidza uye nemazvo, uye chidzidzo ichi chine mukana wekuunza shanduko chaiyo. Iyo sensor yakagadziridzwa ine yakanyanya kunzwa uye kusarudza kune covid, uye inokurumidza uye yakaderera mutengo Said Vikas berry, munyori mukuru webepa" Theunique propertiesye "magic material" graphene inoita kuti iite zvakasiyana-siyana, izvo zvinoita kuti rudzi urwu rwe sensor ivepo.
Graphene imhando yezvinhu zvitsva zvine SP2 hybrid yakabatana kabhoni maatomu akanyatso kurongedzerwa mune imwechete-layer maviri-dimensional honeycomb lattice chimiro. Maatomu e<em>carbon anobatanidzwa pamwe chete nemakemikari mabhondi, uye kunyungudika kwawo uye kufamba kwawo kunogona kubudisa resonance vibration, inozivikanwawo sephonon, inogona kuyerwa nemazvo. Kana morekuru senge sars-cov-2 ichidyidzana negraphene, inoshandura idzi resonance vibrations nenzira chaiyo uye inogoneka. Izvo zvinogona kushandiswa kwegraphene atomic scale sensors - kubva pakuonekwa kwecovid kusvika kuALS kuenda kugomarara - zvinoramba zvichikura, vaongorori vanodaro.
