I-Copper oxide nanopowderiyimpushana yensimbi ensundu-mnyama enezinhlobonhlobo zokusetshenziswa.Ngaphezu kwendima yama-catalysts nezinzwa, indima ebalulekile ye-nano copper oxide i-antibacterial.

Inqubo ye-antibacterial ye-metal oxides ingachazwa kalula ngokuthi: Ngaphansi kokuvuswa kokukhanya okunamandla amakhulu kunegebe le-band, amapheya e-hole-electron akhiqiziwe ahlangana ne-O2 ne-H2O endaweni ezungezile, kanye nezinhlobo ze-oksijeni ezisebenzayo ezikhiqizwayo namanye ama-radicals mahhala. amakhemikhali asabele nama-molecule e-organic esitokisini, ngaleyo ndlela abola iseli futhi azuze umphumela we-antibacterial.Njengoba i-CuO iwuhlobo lwe-p-semiconductor, inezimbobo (CuO) +, ezingase zihlanganyele nemvelo ukudlala umphumela wokulwa namagciwane.
Ucwaningo luye lwabonisa ukuthi i-nano CuO inekhono elihle lokulwa namagciwane ngokumelene ne-pneumonia kanye ne-Pseudomonas aeruginosa.Ukwengeza i-nano copper oxide kumapulasitiki, imicu yokwenziwa, izinto zokunamathisela nezingubo zokugqoka kungagcina umsebenzi ophezulu isikhathi eside ngisho nasezimweni ezinzima.

Ithimba lamazwe ngamazwe lososayensi abavela eNyuvesi yaseLeuven, iNyuvesi yaseBremen, iLeibniz School of Materials Engineering kanye neNyuvesi yase-Ioannina basebenzise ngempumelelo ama-nano copper oxide compounds kanye ne-immunotherapy ukuze babulale amaseli wesimila kumagundane ngaphandle kokuphindelela komdlavuza.

Ukwelashwa kuwulwazi olusha mayelana nokuzonda kwamathumba ezinhlotsheni ezithile ze-nanoparticles.Ithimba lithole ukuthi amaseli wesimila azwela kakhulu kuma-nanoparticles enziwe nge-copper oxide.
Uma sezingaphakathi emzimbeni, lawa ma-nanoparticles e-copper oxide ayancibilika futhi abe nobuthi, abulale amangqamuzana omdlavuza endaweni.Isihluthulelo somklamo omusha we-nanoparticle ukungezwa kwe-iron oxide, evumela ukuthi ibulale amangqamuzana omdlavuza ngenkathi igcina amangqamuzana anempilo eqinile, abacwaningi. kusho.

Ama-metal oxides angaba yingozi uma siwadla ngobuningi, kodwa esikalini se-nanoscale nasezindaweni ezilawulwayo, eziphephile, awabi nangozi.
