Abantu bajonga i-oxide nanoenzymes njengezona zixhobo ezifanelekileyo zokulinganisa ukunyangwa kwe-oxidative stress-mediated pathophysiological disorders yi-antioxidant enzymes, kodwa umsebenzi we-catalytic we-oxide nanoenzymes awukaneliseki.
Ukujonga oku, uTang Zhiyong, uWang Hao, uXingxin Fa, uQiao Zengying, kunye nabanye abavela kwiZiko leNanometer yeSizwe baye baxela okokuqala ukuba i-ultra-thin layered.CeO2ngoxinzelelo lwangaphakathi lusetyenziselwa ukumelana ne-nano oxidation.
Iingongoma eziphambili zeli nqaku
Ingongoma ephambili 1. Ngobalo lwethiyori kunye nohlalutyo, kwafunyaniswa ukuba uxinzelelo lomphezulu lweCeO2inxulumene nolungelelwaniso unsaturation ka Ce kunye nobunzimaCeO2.Ngoko ke, i-nanosheets e-ultra-thin-thin ne-thickness ~ 1.2 nm yenziwe, kwaye uxinzelelo lwe-in-plane / ngaphandle koxinzelelo lwendiza lufikelele ~ 3.0% kunye ne-10.0%, ngokulandelanayo.
Inqaku eliphambili 2. Xa kuthelekiswa ne-nanocubes, le nanosheet ye-ultra-thin ye-Ce-O yekhemikhali ibhondi iye yaphucula i-covalence, ibangele ukwanda kwe-2.6 kwi-SOD efanisiweyo (i-superoxide dismutase) umsebenzi we-catalytic kunye nokunyuka kwe-2.5 ngokubanzi kwi-antioxidant umthamo.Ukusebenzisa le ultra-ebhityileyoCeO2Ifilimu enoxinzelelo lwangaphakathi lokunyanga i-ischemic stroke kwi-vivo inomsebenzi ongcono kunamachiza eklinikhi emveli
