Antimicrobial Polyurea Txheej Nrog Rare Earth-Doped

Antimicrobial Polyurea Txheej Nrog Rare Earth-Doped Nano-Zinc Oxide Particles

qhov chaw: AZO MATERIALS Qhov Covid-19 kis thoob qhov txhia chaw tau pom qhov xav tau ceev rau cov tshuaj tiv thaiv kab mob thiab tshuaj tua kab mob rau cov chaw hauv cov chaw pej xeem thiab chaw kho mob. Kev tshawb fawb tsis ntev los no tau luam tawm thaum Lub Kaum Hli 2021 hauv phau ntawv xov xwm Microbial Biotechnology tau pom tias muaj cov nano-Zinc oxide doped sai sai rau cov txheej txheem polyurea uas nrhiav kev daws qhov teeb meem no.Qhov Xav Tau Rau Kev Tu Kom Huv Huv Raws li pom tau los ntawm ntau yam kab mob sib kis, qhov chaw yog qhov chaw ntawm cov kab mob. kis tau tus mob. Qhov kev xav tau ceev ceev, ua tau zoo, thiab tsis muaj tshuaj lom thiab tshuaj tua kab mob thiab tshuaj tua kab mob saum npoo av tau txhawb nqa kev tshawb fawb tshiab hauv kev lag luam biotechnology, kev lag luam chemistry, thiab cov ntaub ntawv science.Ntawm txheej txheej nrog tshuaj tua kab mob thiab tshuaj tua kab mob tuaj yeem txo qhov kev pheej hmoo ntawm kev kis kab mob. thiab tua biostructures thiab microorganisms thaum sib cuag. Lawv cuam tshuam kev loj hlob ntawm cov kab mob los ntawm kev cuam tshuam ntawm cellular membrane. Lawv kuj txhim kho cov khoom ntawm qhov chaw, xws li corrosion resistance thiab durability.Raws li European Center for Disease Control and Prevention, 4 lab tus tib neeg (kwv yees li ob npaug ntawm cov pej xeem ntawm New Mexico) thoob ntiaj teb ib xyoos tau kis tus kab mob kev noj qab haus huv. Qhov no ua rau muaj ze li ntawm 37,000 tus neeg tuag thoob ntiaj teb, nrog rau qhov xwm txheej tshwj xeeb yog qhov tsis zoo hauv cov tebchaws tsim kho uas tib neeg yuav tsis muaj kev nkag mus rau kev huv huv thiab kev noj qab haus huv zoo. Nyob rau hauv lub ntiaj teb sab hnub poob, HCAIs yog qhov thib rau loj tshaj plaws ua rau tuag.Txhua yam muaj kev cuam tshuam los ntawm cov kab mob thiab kab mob - zaub mov, khoom siv, qhov chaw thiab phab ntsa, thiab textiles tsuas yog qee qhov piv txwv. Txawm tias lub sijhawm ua kom huv huv tsis tu ncua yuav tsis tua txhua tus microbe uas muaj nyob rau ntawm qhov chaw, yog li yuav tsum tau tsim cov txheej txheem tsis muaj tshuaj lom uas tiv thaiv kev loj hlob ntawm microbial los ntawm qhov tshwm sim.Nyob rau hauv cov ntaub ntawv ntawm Covid-19, cov kev tshawb fawb tau pom tias tus kab mob tuaj yeem ua haujlwm. nyob rau ntawm cov hlau tsis tu ncua thiab cov khoom yas ntev txog li 72 teev, ua kom pom qhov xav tau ceev rau cov txheej txheej nrog cov khoom tiv thaiv kab mob. Antimicrobial nto tau siv nyob rau hauv kev kho mob rau ntau tshaj kaum xyoo, tau siv los tswj MRSA tshwm sim.Zinc Oxide - Kev Tshawb Fawb Dav Hlau Tshuaj Tiv Thaiv Zinc oxide (ZnO) muaj cov tshuaj tua kab mob thiab tshuaj tua kab mob. Kev siv ZnO tau tshawb fawb ntau hauv xyoo tas los no los ua cov khoom muaj nyob hauv ntau cov tshuaj tua kab mob thiab tshuaj tua kab mob. Ntau cov kev tshawb fawb toxicity tau pom tias ZnO zoo li tsis muaj tshuaj lom rau tib neeg thiab tsiaj txhu tab sis muaj txiaj ntsig zoo ntawm kev cuam tshuam cov hnab ntawv cellular ntawm cov kab mob.Cov kab mob tua kab mob ntawm Zinc oxide tuaj yeem raug ntaus nqi rau ob peb lub zog. Zn2+ ions raug tso tawm los ntawm ib feem ntawm kev sib cais ntawm Zinc Oxide cov khoom uas cuam tshuam ntxiv kev tiv thaiv kab mob txawm tias nyob hauv lwm cov kab mob tam sim no, nrog rau kev sib cuag ncaj qha nrog cov phab ntsa ntawm tes thiab tso tawm cov pa oxygen reactive. : Cov khoom me me thiab cov kev daws teeb meem ntau dua ntawm Zinc nanoparticles tau nce cov tshuaj tiv thaiv kab mob. Zinc Oxide nanoparticles uas yog me me nkag tau yooj yim dua rau hauv cov microbial cell membrane vim lawv qhov loj interfacial cheeb tsam. Ntau qhov kev tshawb fawb, tshwj xeeb tshaj yog rau Sars-CoV-2 tsis ntev los no, tau piav qhia zoo ib yam li kev tiv thaiv kab mob.Sing RE-Doped Nano-Zinc Oxide thiab Polyurea Coatings los tsim Surfaces nrog Superior Antimicrobial Properties Pab pawg ntawm Li, Liu, Yao, thiab Narasimalu tau thov. Ib txoj hauv kev los npaj cov txheej txheem antimicrobial polyurea sai sai los ntawm kev qhia txog qhov tsis tshua muaj-lub ntiaj teb-doped nano-Zinc Oxide hais tsim los ntawm kev sib xyaw cov nanoparticles nrog lub ntiaj teb tsawg hauv nitric acid.ZnO nanoparticles tau doped nrog Cerium (Ce), Praseodymium (Pr), Lanthanum ( LA), thiab Gadolinium (Gd.) Lanthanum-doped nano-Zinc Oxide hais tau pom tias muaj 85% zoo tiv thaiv kab mob P. aeruginosa thiab E. Coli kab mob.Cov nanoparticles no tseem nyob 83% zoo ntawm tua cov kab mob, txawm tias tom qab 25 feeb. ntawm raug UV teeb. Cov doped nano-Zinc Oxide cov khoom tshawb nrhiav hauv txoj kev tshawb no yuav qhia tau tias UV lub teeb tau zoo dua thiab cov lus teb thermal rau qhov kub thiab txias. Bioassays thiab deg characterization kuj muab pov thawj tias qhov chaw khaws lawv cov tshuaj tua kab mob tom qab siv dua.Polyurea coatings kuj muaj qhov ua tau zoo thiab tsis tshua muaj kev pheej hmoo ntawm tev tawm ntawm qhov chaw. Lub durability ntawm qhov chaw ua ke nrog cov tshuaj tiv thaiv kab mob thiab ib puag ncig cov lus teb ntawm nano-ZnO cov khoom muab kev txhim kho rau lawv lub peev xwm rau kev siv tau zoo hauv ntau qhov chaw thiab kev lag luam. Muaj peev xwm siv tau qhov kev tshawb fawb no qhia tau tias muaj peev xwm loj heev rau kev tswj hwm kev sib kis yav tom ntej thiab txwv tsis pub cov kis ntawm HPAIs hauv kev kho mob. Kuj tseem muaj peev xwm rau lawv siv hauv kev lag luam khoom noj khoom haus los muab cov ntim tshuaj tua kab mob thiab cov fibers, txhim kho qhov zoo thiab txee-lub neej ntawm cov khoom noj khoom haus yav tom ntej. Txawm hais tias qhov kev tshawb fawb no tseem nyob rau hauv nws cov me nyuam mos, nws yuav tsis muaj kev ntseeg sai sai yuav tsiv tawm ntawm chav kuaj thiab mus rau kev lag luam.
