E manatu tagata o le oxide nanoenzymes o mea sili ona talafeagai catalytic mo le faʻataʻitaʻiina o le togafitiga o faʻamaʻi faʻamaʻi faʻamaʻi faʻamaʻi faʻamaʻi e ala i enzymes antioxidant, ae o le gaioiga faʻamalosi o nanoenzymes oxide e le o faʻamalieina pea.
I le silasila atu i lenei mea, o Tang Zhiyong, Wang Hao, Xingxin Fa, Qiao Zengying, ma isi mai le National Nanometer Center ua lipotia mo le taimi muamua e sili ona manifinifi layered.CeO2fa'atasi ai ma fa'alavelave fa'apitoa e fa'aaogaina mo le fa'ama'iina o le nano oxidation.
Manatu autu o lenei tusiga
Manatu autu 1. E ala i le fa'atatauga fa'atatau ma au'ili'iliga, na maua ai le mamafa o luga oleCeO2e fesoʻotaʻi ma le faʻamaopoopoina unsaturation o Ce ma le mafiafia oCeO2.O le mea lea, o nanosheets ultra-manifinifi ma se mafiafia o ~ 1.2 nm sa synthesized, ma o le atuatuvale i totonu-vaalele / fafo o le popole vaalele oo atu ~ 3.0% ma ~ 10.0%, faasologa.
Manatu autu 2. Pe a faatusatusa i nanocubes, o lenei ultra-thin nanosheet Ce-O chemical bond ua faʻaleleia le covalence, e mafua ai le faʻateleina o le 2.6 i le faʻaogaina o le SOD (superoxide dismutase) catalytic activity ma le aofaʻi atoa o le 2.5 faʻateleina le malosi antioxidant.Fa'aogaina lenei ultra-manifinifiCeO2ata tifaga fa'atasi ai ma fa'alavelave fa'apitoa e togafitia ai le stroke ischemic i vivo e sili atu lona fa'atinoga nai lo vaila'au fa'apitoa masani
