Vanhu vanotora oxide nanoenzymes seyakanyanya kukodzera zvinhu zvinokonzeresa kutevedzera kurapwa kweoxidative kusagadzikana-mediated pathophysiological kusagadzikana ne antioxidant enzymes, asi catalytic chiitiko cheoxide nanoenzymes haisati yagutsikana.
Tichifunga izvi, Tang Zhiyong, Wang Hao, Xingxin Fa, Qiao Zengying, nevamwe vanobva kuNational Nanometer Center vakashuma kekutanga kuti ultra-thin layered.CeO2ine intrinsic stress inoshandiswa kune nano oxidation resistance.
Pfungwa huru dzechinyorwa chino
Pfungwa inokosha 1. Kuburikidza nekuverenga kuverenga uye kuongorora, zvakaonekwa kuti kushushikana kwepamusoro kweCeO2ine hukama nekubatanidza unsaturation yeCe uye ukobvu hweCeO2.Nokudaro, ma-ultra-thin nanosheets ane hutema hwe ~ 1.2 nm akagadzirwa, uye mu-ndege kushungurudzika / kunze kwekunetseka kwendege kwakasvika ~ 3.0% uye ~ 10.0%, maererano.
Pfungwa inokosha 2. Inofananidzwa ne nanocubes, iyi ultra-thin nanosheet Ce-O chemical bond yakasimbisa covalence, zvichiita kuti 2.6 fold kuwedzera musimulated SOD (superoxide dismutase) catalytic basa uye yakawanda 2.5 fold kuwedzera antioxidant simba.Kushandisa izvi zvakanyanya-muteteCeO2firimu rine intrinsic kushushikana kurapa ischemic sitiroko mu vivo ine kuita kurinani pane echinyakare kiriniki mishonga
