Lub tuam txhab Austria cov lus, tsim los ntawm cov kws tshawb fawb ntawm Vienna Technical University, ua ke nrog cov lus tshwj xeeb ntawm cov kab noj hniav ntawm cov tub rog kab noj hniav-19.
"Qhov no yog qhov zoo tshaj plaws cov duab qhia tau li cas coronavirus zoo li cas. Nrog kev pab ntawm niaj hnub thev naus laus zis, nws yog qhov tseeb tiag ua tsis tau. Tag nrho cov duab uas tshwm nyob hauv xov xwm yog qauv. Peb xav muab cov pej xeem nrog tus duab tiag tiag ntawm tus kab mob hauv 3D, "Tus Thawj Coj, Tus Thawj Coj Nanographics.
Tus qauv 3D tau tsim los ntawm cov txheej txheem ntawm cryoelectronic tomography: cov qauv khov ntawm tus kab mob tau luam tawm ntawm cov ces kaum sib txawv uas siv lub tsom iav hluav taws xob sib txawv. Tom qab ntawd cov ntaub ntawv tau txais tau raug hloov mus rau hauv cov duab peb-seem. Tom qab ntawd nanographs tshem tawm suab nrov los ntawm qhov chaw, tsom nws thiab muab kho qhov muag thiab cov xim.
Raws li qhov tshwm sim, nws tau muab tawm cov duab ntawm lub plhaub spherical plhaub qauv ntawm SARS-CE-2, los ntawm qhov twg nws nto moo "spikes" saib xyuas. Qhov no s-protein yog qhov tseem ceeb tshaj plaws ntawm "crown" ntawm tus kab mob, uas npog cov particle sheath, zoo li txha caj qaum. Txij ntawm no thiab lawv lub npe - Spike (txhais los ntawm Lus Askiv - "SCHIP"), thiab nws yog qhov tseeb tiv thaiv cov tshuaj tiv thaiv tuab uas cov tshuaj tiv thaiv kab mob los tiv thaiv kab mob.
Raws li cov kws tshawb fawb, qhov ntev ntawm tus kab mob kab mob tsawg dua li qhov pom lub teeb, yog li ntawd, piv txwv li, nws tsis muaj xim. Yog li liab dawb thiab xiav ntxoov ntxoo ntawm tus duab sawv cev yog cuav. Lawv xav tau lawv kom zoo dua qhia cov duab thiab ntau qhov chaw ntawm SARS-CE-2. "Cov kws tshawb fawb muaj kev tshuaj tiv thaiv cov tshuaj tiv thaiv thiab cov tshuaj yuav tsum paub cov qauv molecules. Yog tias lawv pom nws hauv daim ntawv peb-seem, nws yuav yooj yim dua los saib seb lawv ua haujlwm li cas, "Mindek ntxiv.
Yav dhau los, Lavxias teb sab science biomedicine pom cov ncauj lus kom ntxaws peb-seem-1 qauv nrog kev daws teeb meem rau ib tus atoms. Txawm li cas los xij, nws yog nce rau kev tshawb fawb txog cov qauv ntawm cov neeg sib dhos, nrog rau cov khoom uas tau txais los ntawm cov tshuaj uas muaj tus kabmob.
