Dahaarka Antimicrobial Polyurea oo leh Qaybo Nano-Zinc Oxide ah oo Nano-Zinc Oxide ah oo Naadirka ah
source:AZO MATERIALS Faafida Covid-19 waxay muujisay baahida degdega ah ee daaha ka-hortagga fayraska iyo ka-hortagga jeermiska ee sagxadaha goobaha dadweynaha iyo goobaha daryeelka caafimaadka. Cilmi-baaristii ugu dambeysay ee lagu daabacay Oktoobar 2021 joornaalka Microbial Biotechnology waxay muujisay diyaargarow degdeg ah oo nano-Zinc oxide ah oo loogu talagalay daaha polyurea ee doonaya in wax laga qabto arrintan. gudbinta. Baahida degdega ah ee kiimikooyinka degdega ah, wax ku oolka ah, iyo kuwa aan sunta ahayn iyo dahaarka ka-hortagga jeermiska iyo fayraska ayaa kiciyay cilmi-baaris cusub oo ku saabsan cilmiga bayoolajiga, kiimikada warshadaha, iyo sayniska qalabka. waxayna dilaan noolaha iyo noolaha marka la taabto. Waxay hor istaagaan korriinka noolaha iyada oo loo marayo carqaladaynta xuubka gacanta. Waxay sidoo kale wanaajiyaan sifooyinka dusha sare, sida caabbinta daxalka iyo adkeysiga. Sida laga soo xigtay Xarunta Yurub ee Xakamaynta iyo Kahortagga Cudurrada, 4 milyan oo qof (qiyaastii laba jeer dadweynaha New Mexico) adduunka oo dhan sanadkiiba waxay helayaan caabuq la xiriira daryeelka caafimaadka. Tani waxay keenaysaa in ku dhawaad 37,000 oo dhimasho ah adduunka oo dhan, iyadoo xaaladdu ay si gaar ah ugu xun tahay waddamada soo koraya halkaas oo laga yaabo in dadku aanay heli karin nadaafad habboon iyo kaabayaasha nadaafadda daryeelka caafimaadka. Dunida Galbeedka, HCAIs waa sababta lixaad ee ugu weyn ee dhimashada. Wax walbaa waxay u nugul yihiin wasakheynta microbes iyo fayrasyada - cuntada, qalabka, sagxadaha iyo derbiyada, iyo dunta ayaa ah tusaalooyin qaar. Xataa jadwallada nadaafadda ee caadiga ah ma dili karaan microbe kasta oo ku yaal sagxadaha, sidaa darteed waxaa jirta baahi adag oo loo qabo in la sameeyo dahaar aan sun ahayn oo ka hortagaya korriinka microbial inay dhacaan. Xaaladda Covid-19, daraasaduhu waxay muujiyeen in fayrasku sii shaqeyn karo Dusha sare ee birta iyo caagagga ah ee sida badan loo taabto ilaa 72 saacadood, taasoo muujinaysa baahida degdega ah ee dahaarka dusha sare leh ee leh sifooyinka fayraska. Dusha sare ee ka hortagga jeermiska ayaa loo isticmaalay goobaha daryeelka caafimaadka muddo ka badan toban sano, iyadoo loo isticmaalay in lagu xakameeyo dillaaca MRSA. Zinc Oxide - Kiimikada Kiimikada Ka-hortagga ah ee Si Balaadhan loo Baadhay Isticmaalka ZnO ayaa si xooggan loo sahamiyay sannadihii u dambeeyay iyada oo ah walxo firfircoon oo kiimikooyin antimicrobial iyo fayrus ah oo badan. Daraasado badan oo sunta ah ayaa lagu ogaaday in ZnO ay tahay mid aan sun u ahayn dadka iyo xayawaanka laakiin aad waxtar ugu leh khalkhalgelinta baqshadaha gacanta ee noolaha. Zn2+ ions waxaa lagu sii daayaa qayb ahaan kala diri qayb ka mid ah qaybaha Zinc Oxide taas oo carqaladeynaysa hawlaha antimicrobial dheeraad ah xitaa microbes kale oo jooga, iyo sidoo kale xiriir toos ah oo la leh derbiyada unugyada iyo sii deynta noocyada oksijiinta falcelinta. Qaybaha yaryar iyo xalalka xoojinta sare ee nanoparticles Zinc waxay kordhiyeen waxqabadka antimicrobial. Nanoparticles Zinc Oxide oo ka yar cabbirkoodu waxay si fudud u galaan xuubka unugga microbial sababtoo ah aaggooda weyn ee isdhexgalka. Daraasado badan, gaar ahaan Sars-CoV-2 dhawaan, ayaa caddeeyey tallaabo isku mid ah oo wax ku ool ah oo ka dhan ah fayrasyada.Isticmaalka dib-u-Doped Nano-Zinc Oxide iyo Polyurea Coatings si loo Abuuro Dusha sare ee Guryaha Ka-hortagga Ka-hortagga SareKooxda Li, Liu, Yao, iyo Narasimalu ayaa soo jeediyay hab si degdeg ah loogu diyaariyo daahan polyurea antimicrobial iyadoo la soo bandhigayo naadir-dhul-doped Qaybaha nano-Zinc Oxide ee la abuuray iyada oo la isku darayo nanoparticles leh dhul naadir ah oo ku jira nitric acid. Nanoparticles ZnO waxaa lagu daray Cerium (Ce), Praseodymium (Pr), Lanthanum (LA), iyo Gadolinium (Gd.) Lanthanum-doped nano-Zinc Qaybaha Oxide ayaa la ogaaday inay 85% waxtar u leeyihiin P. aeruginosa iyo E. Coli bakteeriyada Nanoparticles-yadan ayaa sidoo kale ah 83% waxtar u leh dilka microbes, xitaa ka dib 25 daqiiqo ee soo-gaadhista iftiinka UV. Qaybaha nano-Zinc Oxide ee lagu sameeyay daraasadda ayaa laga yaabaa inay muujiyaan jawaabta iftiinka UV oo soo hagaagtay iyo ka jawaab celinta kulaylka ee isbedelka heerkulka. Bioassays iyo sifada dusha sare waxay sidoo kale bixisay caddayn ah in dusha sare ay sii hayaan hawlahooda ka hortagga jeermiska ka dib isticmaalka soo noqnoqda. Daaha polyurea sidoo kale waxay leeyihiin adkeysi sare leh oo khatar yar oo ah inay ka soo baxaan dusha sare. Adkeysiga sagxadaha oo ay weheliso waxqabadyada lidka ku ah jeermiska iyo jawaab celinta deegaanka ee qaybaha nano-ZnO waxay bixiyaan hagaajinta kartidooda codsiyada wax ku oolka ah ee goobaha kala duwan iyo warshadaha. gudbinta HPAIs ee goobaha daryeelka caafimaadka. Waxa kale oo jira suurtogalnimada isticmaalkooda warshadaha cuntada si ay u bixiyaan baakadaha antimicrobial iyo fiilooyinka, hagaajinta tayada iyo nolosha shelf ee cuntooyinka mustaqbalka. In kasta oo ay cilmi-baadhistani weli curdin tahay, haddana waxa aan shaki ku jirin in ay dhawaan ka guuri doonto shaybaadhka oo ay u gudbi doonto dhinaca ganacsiga.
