"Zvinhu zvemashiripiti" graphene inogona kushandiswa kuona COVID-19 nekukurumidza uye nemazvo
Sekureva kwemishumo yenhau dzekunze, vaongorori vepaYunivhesiti yeIllinois kuChicago vakabudirira kushandisa graphene, chimwe chezvinhu zvakasimba uye zvakatetepa zvinozivikanwa, kuona hutachiona hwesars-cov-2 mukuyedza murabhoritari. Zvakawanikwa izvi zvinogona kunge zviri budiriro mukuona COVID-19 uye zvinogona kushandiswa mukurwisa COVID-19 nemhando dzayo, vaongorori vanodaro.
Mukuyedza uku, vaongorori vakasanganisamapepa egrapheneine ukobvu hwe1/1000 chete zvitambi zvine antibody yakagadzirirwa kurwisa maglycoprotein ane mukurumbira paCOVID-19. Vakazoyera kutenderera kweatomu kwemapepa egraphene pavakasangana nemasampuli ese ari maviri ecowid positive necowid negative mumate ekugadzira. Kutenderera kwepepa regraphene rakabatana neantibody kwakachinja pavakarapwa nemasampuli akanaka ecowid-19, asi hakuna kuchinja pavakarapwa nemasampuli asina kunaka ecowid-19 kana mamwe ma coronavirus. Kuchinja kwekudengenyeka kwakayerwa nemuchina unonzi Raman spectrometer kunoonekwa mumaminitsi mashanu. Zvakawanikwa zvavo zvakaburitswa muACS Nano musi wa15 Chikumi, 2021.
"Vanhu vanoda nzira dziri nani dzekuona covid nemarudzi ayo nekukurumidza uye nemazvo, uye chidzidzo ichi chine mukana wekuunza shanduko chaiyo. Sensor yakagadziriswa ine hunhu hwepamusoro uye sarudzo kune covid, uye inokurumidza uye inodhura zvishoma. Said Vikas berry, munyori mukuru wepepa" Thezvivakwa zvakasiyanagraphene ye "zvinhu zvemashiripiti" inoita kuti ikwanise kushandiswa zvakasiyana-siyana, izvo zvinoita kuti rudzi urwu rwesensa ruvepo.
Graphene rudzi rwezvinhu zvitsva zvine maatomu ecarbon akabatana neSP2 hybrid akabatanidzwa zvakasimba muchimiro che single-layer two-dimensional honeycomb lattice structure. Maatomu ecarbon anobatanidzwa pamwe chete nemakemikari bonds, uye elasticity yavo nekufamba kwavo zvinogona kugadzira resonance vibration, inozivikanwawo sephonon, iyo inogona kuyerwa nemazvo. Kana molekyuru yakaita sars-cov-2 ikasangana negraphene, inoshandura resonance vibration idzi nenzira chaiyo uye inoverengerwa. Vaongorori vanoti mashandisirwo anogona kuitwa negraphene atomic scale sensors - kubva pakuona covid kusvika ALS kusvika kugomarara - ari kuramba achikura.
