Cov khoom compression yog tam sim no ua tau

Ib pawg ntawm cov kws tshawb fawb ntawm Massachusetts Institute of Technology tau tsim txoj hauv kev kom sai thiab pheej yig txo cov khoom mus rau nanoscale. Cov txheej txheem no hu ua txheej txheem implosion. Raws li kev tshaj tawm hauv phau ntawv Journal Science, nws siv cov khoom nqus dej ntawm cov polymer hu ua polyacrylate.

Siv cov txheej txheem no, cov kws tshawb fawb tsim cov duab thiab cov qauv uas lawv xav kom txo qis los ntawm kev ua qauv ntawm cov khoom siv polymer nrog lub laser. Cov ntsiab lus yuav tsum tau zoo, xws li hlau, quantum dots los yog DNA, yog txuas rau lub scaffold los ntawm fluorescein molecules uas khi rau polyacrylate.

Tshem tawm cov dej noo nrog cov kua qaub txo qhov loj ntawm cov khoom. Hauv kev sim ua tiav ntawm MIT, cov khoom txuas nrog polyacrylate shrink sib npaug mus rau ib txhiab ntawm nws qhov loj me. Cov kws tshawb fawb hais txog, ua ntej ntawm tag nrho cov, qhov pheej yig ntawm cov txheej txheem ntawm "shrinkage" ntawm cov khoom.
