Nanocenter Qaranka JACS: Aad u khafiif ah CeO2 nano antioxidant

Dhul dhif ah 3
Dadku waxay u tixgeliyaan nanoenzymes oxide inay yihiin qalabka ugu habboon ee kicinta ee loogu talagalay jilitaanka daaweynta walaaca oksijiinta-dhexdhexaadinta cudurrada pathophysiological ee enzymes-ka antioxidant, laakiin dhaqdhaqaaqa kicinta ee nanoenzymes oxide weli waa mid aan ku qanacsanayn.

Iyadoo taas la eegayo, Tang Zhiyong, Wang Hao, Xingxin Fa, Qiao Zengying, iyo kuwa kale oo ka socda Xarunta Nanometerka Qaranka ayaa markii ugu horeysay ka warbixiyay lakabyo khafiif ah oo khafiif ah.CeO2oo leh diiqad gudaha ah ayaa loo isticmaalaa iska caabinta nano oksaydhaynta.

Qodobbada muhiimka ah ee maqaalkan

Qodobka muhiimka ah 1. Iyadoo loo marayo xisaabinta aragtida iyo falanqaynta, waxaa la ogaaday in cadaadiska dusha sare eeCeO2waxay la xiriirtaa isuduwidda unsaturation Ce iyo dhumucdaCeO2. Sidaa darteed, nanosheets aadka u dhuuban oo dhumucdiisu tahay ~ 1.2 nm ayaa la farsameeyey, iyo walbahaarka diyaaradda / kadeedka diyaaradda ayaa gaadhay ~ 3.0% iyo ~ 10.0%, siday u kala horreeyaan.

Qodobka muhiimka ah 2. Marka la barbardhigo nanocubes, nanosheet aadka u dhuuban ee Ce-O kiimikaad kiimikaad ayaa wanaajiyay isku xirnaanta, taasoo keentay kororka 2.6 laabma ee SOD-ga la ekaysiiyay (superoxide dismutase) dhaqdhaqaaqa kicinta iyo guud ahaan 2.5 laablaab kordhinta awoodda antioxidant. Codsigan aadka u dhuubanCeO2filimka leh diiqad gudaha ah oo lagu daweynayo istaroogga ischaemic in vivo wuxuu leeyahay waxqabad ka wanaagsan dawooyinka caafimaad ee dhaqameed
