Antimicrobial Polyurea Coatings Ine Rare Earth-Doped Nano-Zinc Oxide Particles
kwakabva:AZO MATERIALSDenda reCovid-19 rakaratidza kudiwa kwekukurumidzira kweantiviral uye antimicrobial coatings munzvimbo munzvimbo dzeveruzhinji nenzvimbo dzehutano. Tsvagiridzo ichangoburwa yakabudiswa muna Gumiguru 2021 mujenari Microbial Biotechnology yakaratidza kukurumidza nano-Zinc oxide doped gadziriro ye polyurea coating iyo inoda kugadzirisa nyaya iyi. kutapurirana. Kudiwa kwekukasika, kunoshanda, uye kusina chepfu uye maantimicrobial uye antiviral pamusoro pekuputira kwakakurudzira tsvakiridzo itsva mundima dzebiotechnology, kemisitiri yeindasitiri, nesainzi yezvigadzirwa.Marairi epamusoro ane antiviral uye antimicrobial action anogona kuderedza njodzi yekutapurirwa kwehutachiona. uye kuuraya biostructures uye microorganisms pakubata. Ivo vanotadzisa kukura kwema microorganisms kuburikidza ne cell membrane kukanganisa. Vanovandudzawo zvinhu zvepamusoro, zvakadai sekudzivirira kusvibiswa uye kusimba.Sekureva kweEuropean Center for Disease Control and Prevention, vanhu vane mamiriyoni mana (kanenge kaviri nhamba yevanhu veNew Mexico) pasi rose pagore vanowana hutachiona hunoenderana nehutano. Izvi zvinotungamira kufa kwevanhu vanosvika zviuru makumi matatu nenomwe pasi rose, nemamiriro ezvinhu akanyanya kushata munyika dzichiri kusimukira uko vanhu vangangotadza kuwana hutsanana hwakakwana uye hutano hwehutano. Munyika dzekuMadokero, HCAIs ndicho chikonzero chechitanhatu chikuru cherufu.Chinhu chose chinotapukirwa neutachiona nemavhairasi - chikafu, midziyo, nzvimbo nemadziro, uye machira ingori mimwe mienzaniso. Kunyangwe zvirongwa zvehutsanana zvenguva dzose zvinogona kusauraya hutachiona hwese huripo pamusoro, saka pane chinodiwa chekugadzira machira asina muchetura anodzivirira kukura kwehutachiona kubva kuitika. Munyaya yeCovid-19, zvidzidzo zvakaratidza kuti hutachiona hunogona kuramba huchishanda. panzvimbo dzinowanzobatwa-batwa-stainless simbi uye epurasitiki kwemaawa anosvika makumi manomwe nemaviri, zvichiratidza kudiwa kwekukurumidzira kwekuputira pamusoro ane antiviral properties. Antimicrobial surfaces yakashandiswa muhutano hwehutano kwemakore anopfuura gumi, ichishandiswa kudzora kubuda kweMRSA.Zinc Oxide - A Widely Explored Antimicrobial Chemical CompoundZinc oxide (ZnO) ine antimicrobial ine simba uye antiviral properties. Kushandiswa kweZnO kwakaongororwa zvakanyanya mumakore achangopfuura sechinhu chinoshanda mune akawanda antimicrobial uye antiviral makemikari. Zvidzidzo zvakawanda zvehuchetura zvakawana kuti ZnO inenge isiri chepfu kuvanhu nemhuka asi inoshanda zvakanyanya pakuvhiringa maenvelope emasero ezvipembenene.Maitirwo ekuuraya utachiona hweZinc oxide anogona kunzi ane zvinhu zvishoma. Zn2 + ions inosunungurwa nekuparara kwechikamu cheZinc Oxide particles izvo zvinokanganisa mamwe antimicrobial action kunyange mune mamwe ma microbes aripo, pamwe chete nekubatana zvakananga nemasero emadziro uye kusunungurwa kwemhando yeokisijeni inoshandiswa.Zinc Oxide antimicrobial activity inobatanidzwawo nekukura kwechidimbu uye kuisa pfungwa. : zvidimbu zvidiki uye yakakwirira yekumisikidza mhinduro yeZinc nanoparticles yakawedzera antimicrobial chiitiko. Zinc Oxide nanoparticles idiki muhukuru inopinda zviri nyore mumicrobial cell membrane nekuda kwenzvimbo yadzo yakakura yakatarisana. Zvidzidzo zvakawanda, kunyanya muSars-CoV-2 nguva pfupi yadarika, zvakajekesa chiito chinoshanda kurwisa mavhairasi.Kushandisa RE-Doped Nano-Zinc Oxide uye Polyurea Coatings Kugadzira Surfaces ine Superior Antimicrobial PropertiesChikwata cheLi, Liu, Yao, naNarasimalu chakurudzira. nzira yekukurumidza kugadzirira antimicrobial polyurea coatings nekuisa zvisingawanzo-doped pasi-doped nano-Zinc Oxide particles yakagadzirwa nekusanganisa nanoparticles nepasi risingawanzo mu nitric acid.ZnO nanoparticles dzakagadzirwa neCerium (Ce), Praseodymium (Pr), Lanthanum ( LA), uye Gadolinium (Gd.) Lanthanum-doped nano-Zinc Oxide particles yakawanikwa iine 85% inoshanda paP. aeruginosa uye E. Coli mabhakitiriya strains. Aya nanoparticles anorambawo 83% anobudirira pakuuraya utachiona, kunyange mushure memaminitsi makumi maviri nemashanu. kuratidzwa kune UV mwenje. Iyo doped nano-Zinc Oxide zvidimbu zvakaongororwa muchidzidzo zvinogona kuratidza yakagadziridzwa UV mwenje mhinduro uye yekupisa inopindura kune tembiricha shanduko. Bioassays uye chimiro chepamusoro chakapawo humbowo hwekuti nzvimbo dzinochengeta mashandiro emishonga inorwisa utachiona mushure mekushandisa kasingaperi.Polyurea coatings inewo kusimba kwakanyanya uye ine njodzi shoma yekusvuura nzvimbo. Kusimba kwenzvimbo pamwe chete nemishonga inorwisa utachiona uye mhinduro yezvakatipoteredza yezvimedu zve nano-ZnO zvinopa kuvandudzwa kwekwaniso yazvo yekushandiswa kunoshanda munzvimbo dzakasiyana siyana uye mumaindasitiri. kutapurirana kweHPAIs munzvimbo dzehutano. Kune zvakare mukana wekushandiswa kwavo muindasitiri yechikafu kupa antimicrobial kurongedza uye mafiber, kuvandudza kunaka uye sherufu-hupenyu hwechikafu mune ramangwana. Nepo tsvagiridzo iyi ichiri kutanga, pasina mubvunzo ichave ichibuda murabhoritari ichienda munharaunda yekutengeserana.
