Zovala za Antimicrobial Polyurea Zokhala Ndi Zosowa Padziko Lapansi

Zopaka za Antimicrobial Polyurea Zokhala Ndi Tinthu Zosowa Zapadziko Lopanda Nano-Zinc Oxide

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 yemwe adasindikizidwa mu Okutobala 2021 mu nyuzipepala ya Microbial Biotechnology yawonetsa kukonzekera kwachangu kwa nano-Zinc oxide doped kwa zokutira za polyurea zomwe zikufuna kuthana ndi vutoli. Kufunika kokakamizika kwamankhwala othamanga, ogwira mtima, komanso opanda poizoni ndi zokutira zothira ndi antimicrobial ndi antiviral pamwamba kwalimbikitsa kufufuza kwatsopano pankhani ya biotechnology, chemistry yamakampani, ndi sayansi yazinthu.Zopaka zapamwamba zokhala ndi antiviral ndi antimicrobial action zitha kuchepetsa kufala kwa ma virus ndikupha tizilombo toyambitsa matenda 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 tomwe timapezeka pamalopo, chifukwa chake pakufunika kupanga zokutira zopanda poizoni zomwe zimalepheretsa kukula kwa tizilombo toyambitsa matenda. 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 tina tating'onoting'ono tating'onoting'ono, komanso kukhudzana kwachindunji ndi makoma a cell ndi kutulutsidwa kwa mitundu yogwira ntchito ya okosijeni. 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 zochita zofananira polimbana ndi ma virus.Kugwiritsa ntchito RE-Doped Nano-Zinc Oxide ndi Polyurea Coatings Kupanga Malo Okhala Ndi Zinthu Zapamwamba Zopha tizilombo toyambitsa matendaGulu la Li, Liu, Yao, ndi Narasimalu lakonza njira yokonzekera mwachangu antimicrobial polimbana ndi tizilombo toyambitsa matenda poyitanira polyureeth-intropedo-zinc. Oxide particles opangidwa ndi 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 anapezeka kuti 85% yogwira motsutsana ndi mabakiteriya a Eruginosal ndi E. 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.Potential UsesKufufuzaku kukuwonetsa kuthekera kwakukulu kowongolera kuphulika kwa mtsogolo ndikuyimitsa kufala kwa ma HPAI m'malo azachipatala. 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.
