Cov neeg suav hais tias oxide nanoenzymes yog cov khoom siv catalytic zoo tshaj plaws rau simulating kev kho mob ntawm oxidative stress-mediated pathophysiological disorders los ntawm antioxidant enzymes, tab sis cov catalytic kev ua si ntawm oxide nanoenzymes tseem tsis txaus siab.
Raws li qhov pom ntawm qhov no, Tang Zhiyong, Wang Hao, Xingxin Fa, Qiao Zengying, thiab lwm tus los ntawm National Nanometer Center tau tshaj tawm thawj zaug tias cov txheej txheej ultra-nyias.CeO 2nrog rau kev nyuaj siab yog siv rau nano oxidation kuj.
Cov ntsiab lus tseem ceeb ntawm kab lus no
Lub ntsiab lus tseem ceeb 1. Los ntawm kev suav theoretical thiab kev tsom xam, nws tau pom tias qhov kev ntxhov siab ntawm qhov chawCeO 2muaj feem xyuam rau kev sib koom tes unsaturation ntawm Ce thiab thickness ntawmCeO 2.Yog li ntawd, ultra-nyias nanosheets nrog ib tug tuab ntawm ~ 1.2 nm tau synthesized, thiab nyob rau hauv lub dav hlau kev nyuaj siab / tawm ntawm lub dav hlau kev nyuaj siab mus txog ~ 3.0% thiab ~ 10.0%, feem.
Lub ntsiab lus tseem ceeb 2. Piv nrog nanocubes, qhov no ultra-thin nanosheet Ce-O tshuaj daim ntawv cog lus tau txhim kho covalence, uas ua rau 2.6 npaug nce hauv simulated SOD (superoxide dismutase) catalytic kev ua si thiab tag nrho 2.5 npaug nce hauv antioxidant muaj peev xwm.Siv no ultra-nyiasCeO 2zaj duab xis nrog cov kev ntxhov siab hauv lub cev los kho ischemic stroke hauv vivo muaj kev ua tau zoo dua li cov tshuaj kho mob ib txwm muaj
