I-copper oxide nanopowderi-brown-black metal oxide powder enoluhlu olubanzi lokusetyenziswa.Ukongeza kwindima ye-catalysts kunye neenzwa, indima ebalulekileyo ye-nano copper oxide i-antibacterial.

Inkqubo ye-antibacterial ye-oxides yensimbi inokuchazwa ngokulula njenge: Ngaphantsi kokuvuswa kokukhanya okunamandla amakhulu kune-gap yebhendi, izibini ezenziwe ngomngxuma-electron zidibana kunye ne-O2 kunye ne-H2O kwindalo, kunye neentlobo ze-oksijini ezisebenzayo kunye nezinye ii-radicals zamahhala. ikhemikhali isabela kunye neemolekyuli eziphilayo kwiseli, ngaloo ndlela ibola iseli kunye nokuphumeza isiphumo sokulwa ne-antibacterial.Kuba iCuO iyi-p-type semiconductor, inemingxuma (CuO) +, enokunxibelelana nokusingqongileyo ukuze idlale isiphumo se-antibacterial.
Uphononongo lubonise ukuba i-nano CuO inamandla okubulala iintsholongwane ngokuchasene nenyumoniya kunye nePseudomonas aeruginosa.Ukongeza i-nano copper oxide kwiiplastiki, iifayibha zokwenziwa, izinto ezincamathelayo kunye neengubo zokwaleka zinokugcina umsebenzi ophezulu ixesha elide nakwindawo ezinzima.

Iqela lamazwe ngamazwe leengcali zenzululwazi ezivela kwiYunivesithi yaseLeuven, iYunivesithi yaseBremen, iLeibniz School of Materials Engineering kunye neYunivesithi yase-Ioannina baye basebenzisa ngempumelelo i-nano copper oxide compounds kunye ne-immunotherapy ukubulala iiseli ze-tumor kwiigundane ngaphandle kokuphindaphinda komhlaza.

Unyango lulwazi olutsha malunga nokucaphuka kwamathumba kwiintlobo ezithile ze-nanoparticles.Iqela lafumanisa ukuba iiseli zethumba zazinovakalelo ngokukodwa kwi-nanoparticles eyenziwe kwi-oxide yobhedu.
Xa sele ingaphakathi emzimbeni, ezi nanoparticles ze-copper oxide zichitha kwaye zibe yityhefu, zibulala iiseli zomhlaza kwindawo.Isitshixo kwi-design entsha ye-nanoparticle kukongeza i-iron oxide, evumela ukuba ibulale iiseli zomhlaza ngelixa igcina iiseli eziphilileyo, abaphandi. watsho.

I-Metal oxides inokuba yingozi xa sizitya ngobuninzi, kodwa kwi-nanoscale kunye nokulawulwa, ugxininiso olukhuselekileyo, alunabungozi.
