Zopaka za Antimicrobial Polyurea Zokhala Ndi Tinthu Zosowa Padziko Lonse za Nano-Zinc Oxide Particles
gwero:AZO MATERIALSMliri wa Covid-19 wawonetsa kufunikira kwachangu kwa zokutira zoteteza ku ma virus ndi ma antimicrobial pamalo opezeka anthu ambiri komanso malo azachipatala. Kafukufuku waposachedwa wofalitsidwa mu Okutobala 2021 mu nyuzipepala ya Microbial Biotechnology awonetsa kukonzekera mwachangu kwa nano-Zinc oxide doped kwa zokutira za polyurea zomwe zikufuna kuthana ndi vutoli. kufala. Kufunika kofulumira, kogwira mtima, komanso kopanda poizoni ndi zokutira pamwamba pa maantimicrobial ndi antivayirasi kwalimbikitsa kafukufuku wamakono pankhani ya sayansi ya sayansi ya zamoyo, chemistry ya mafakitale, ndi sayansi ya zinthu. ndikupha ma biostructures ndi tizilombo tating'onoting'ono tikakumana. Amalepheretsa kukula kwa tizilombo tating'onoting'ono chifukwa cha kusokonezeka kwa nembanemba ya ma cell. Amathandizanso kuti zinthu zapamtunda, monga kukana dzimbiri komanso kukhazikika.Malinga ndi European Center for Disease Control and Prevention, anthu 4 miliyoni (pafupifupi kuwirikiza kawiri ku New Mexico) padziko lonse lapansi pachaka amapeza matenda okhudzana ndi zaumoyo. Izi zimapangitsa kuti anthu pafupifupi 37,000 afa padziko lonse lapansi, pomwe zinthu zimakhala zovuta kwambiri m'maiko omwe akutukuka kumene komwe anthu sangakhale ndi zimbudzi zoyenera komanso zaukhondo. M'mayiko a Kumadzulo, ma HCAI ndi chifukwa chachisanu ndi chimodzi cha imfa.Chilichonse chikhoza kuipitsidwa ndi tizilombo toyambitsa matenda ndi tizilombo toyambitsa matenda - chakudya, zipangizo, malo ndi makoma, ndi nsalu ndi zitsanzo chabe. Ngakhale ndondomeko zaukhondo wanthawi zonse sizingaphe tizilombo tating'onoting'ono tomwe timapezeka pamalopo, chifukwa chake pakufunika kupanga zokutira zopanda poizoni zomwe zimalepheretsa kukula kwa tizilombo toyambitsa matenda. pazitsulo zosapanga dzimbiri ndi pulasitiki zogwidwa pafupipafupi kwa maola 72, kusonyeza kufunikira kwachangu zokutira pamwamba zokhala ndi antiviral properties. Ma antimicrobial surfaces akhala akugwiritsidwa ntchito pazachipatala kwa zaka zopitirira khumi, akugwiritsidwa ntchito poletsa kuphulika kwa MRSA.Zinc Oxide - A Widely Explored Antimicrobial Chemical CompoundZinc oxide (ZnO) ali ndi mphamvu zowononga tizilombo toyambitsa matenda komanso tizilombo toyambitsa matenda. Kugwiritsiridwa ntchito kwa ZnO kwafufuzidwa mozama m'zaka zaposachedwa monga chogwiritsira ntchito mu mankhwala ambiri ophera tizilombo toyambitsa matenda. Kafukufuku wambiri wa kawopsedwe apeza kuti ZnO imakhala yopanda poizoni kwa anthu ndi nyama koma imakhala yothandiza kwambiri pakusokoneza ma envulopu amtundu wa tizilombo tating'onoting'ono.Njira zopha tizilombo toyambitsa matenda a Zinc oxide zitha kukhala chifukwa cha zinthu zingapo. Zn2+ ions amamasulidwa ndi kusungunuka pang'ono kwa Zinc Oxide particles zomwe zimasokoneza ntchito yowonjezereka ya antimicrobial ngakhale mu tizilombo tating'onoting'ono tomwe timakhalapo, komanso kukhudzana mwachindunji ndi makoma a cell ndi kumasulidwa kwa mitundu yambiri ya okosijeni. : Tinthu tating'onoting'ono komanso njira zopangira ndende ya Zinc nanoparticles zawonjezera ntchito za antimicrobial. Zinc Oxide nanoparticles omwe ndi ang'onoang'ono kukula amaloŵa mosavuta mu nembanemba ya cell ya tizilombo chifukwa cha malo awo akuluakulu. Kafukufuku wambiri, makamaka mu Sars-CoV-2 posachedwapa, afotokozanso momwemonso momwe angachitire polimbana ndi ma virus.Kugwiritsa ntchito RE-Doped Nano-Zinc Oxide ndi Polyurea Coatings Kupanga Zomangamanga Zokhala ndi Superior Antimicrobial Properties Gulu la Li, Liu, Yao, ndi Narasimalu lati. njira yokonzekera mwachangu zokutira za antimicrobial polyurea poyambitsa nano-Zinc yosowa kwambiri padziko lapansi. Tinthu ta okosijeni opangidwa mwa kusakaniza nanoparticles ndi osowa nthaka mu nitric acid.The ZnO nanoparticles anali doped ndi Cerium (Ce), Praseodymium (Pr), Lanthanum (LA), ndi Gadolinium (Gd.) Lanthanum-doped nano-Zinc Oxide particles anali anapeza kuti 85% akugwira ntchito motsutsana ndi P. aeruginosa ndi E. Coli bacterial strains. Izi ma nanoparticles amakhalabe 83% ogwira ntchito kupha tizilombo toyambitsa matenda, ngakhale pambuyo pa mphindi 25 za kuwala kwa UV. Tinthu tating'onoting'ono ta nano-Zinc Oxide tomwe tafufuzidwa mu phunziroli titha kuwonetsa kuyankha bwino kwa kuwala kwa UV komanso kuyankha kwamafuta pakusintha kwa kutentha. Ma bioassays ndi mawonekedwe a pamwamba adaperekanso umboni wosonyeza kuti malo amasungabe ntchito zawo zowononga tizilombo toyambitsa matenda pambuyo pogwiritsidwa ntchito mobwerezabwereza.Zovala za Polyurea zimakhalanso zolimba kwambiri ndipo zimakhala ndi chiopsezo chochepa chochotsa pamwamba. Kukhalitsa kwa malo ophatikizika ndi ntchito zowononga tizilombo toyambitsa matenda komanso kuyankhidwa kwa chilengedwe kwa tinthu tating'onoting'ono ta nano-ZnO kumapereka kusintha kwazomwe zingatheke kuti zigwiritsidwe ntchito pazochitika zosiyanasiyana ndi mafakitale. kufalitsa ma HPAI m'malo azaumoyo. Palinso mwayi woti azigwiritsa ntchito m'makampani azakudya kuti azipereka antimicrobial package ndi ulusi, kuwongolera bwino komanso moyo wa alumali wazakudya m'tsogolomu. Ngakhale kuti kafukufukuyu akadali wamng'ono, mosakayikira posachedwapa atuluka mu labotale ndikupita ku gawo lazamalonda.
