Nā ʻāpana Polyurea Antimicrobial me nā ʻāpana Nano-Zinc Oxide Laka honua-Doped
kumu: AZO MATERIALSUa hōʻike ka maʻi maʻi maʻi Covid-19 i ka pono wikiwiki no nā pale antiviral a me nā antimicrobial no nā papa ma nā wahi ākea a me nā wahi mālama olakino. ʻO ka noiʻi hou i paʻi ʻia ma ʻOkakopa 2021 ma ka puke pai Microbial Biotechnology ua hōʻike i kahi hoʻomākaukau doped nano-Zinc oxide wikiwiki no nā uhi polyurea e ʻimi nei e hoʻoponopono i kēia pilikia. hoʻoili. ʻO ka makemake nui i nā meaʻawaʻawa wikiwiki, maikaʻi, a me nā meaʻawaʻawaʻole a me nā antimicrobial a me ka antiviral surface coatings ua hoʻoulu i ka noiʻi hou i nāʻano o ka biotechnology, kaʻenehanaʻoihana, a me nā meaʻepekema. a pepehi i nā biostructure a me nā microorganisms ke hoʻopili ʻia. Kāohi lākou i ka ulu ʻana o nā microorganism ma o ka hoʻopau ʻana i ka membrane cellular. Hoʻomaikaʻi pū lākou i nā waiwai o ka ʻili, e like me ke kūpaʻa ʻana i ka corrosion a me ka lōʻihi. Wahi a ka European Center for Disease Control and Prevention, 4 miliona mau kānaka (ma kahi o ʻelua mau kānaka o New Mexico) ma ka honua holoʻokoʻa i kēlā me kēia makahiki e loaʻa i kahi maʻi e pili ana i ke olakino. Ke alakaʻi nei kēia ma kahi o 37,000 mau make ma ka honua holoʻokoʻa, me ke kūlana koʻikoʻi loa i nā ʻāina ulu kahi i hiki ʻole ai i nā kānaka ke komo i ka hoʻomaʻemaʻe kūpono a me ka hoʻomaʻemaʻe olakino. Ma ka honua Komohana, ʻo ka HCAI ke ono o ka nui o ka make. Hiki i nā mea a pau ke hoʻopōʻino ʻia e nā microbes a me nā maʻi - nā meaʻai, nā mea hana, nā ʻili a me nā paia, a me nā textiles kekahi mau hiʻohiʻona. ʻAʻole hiki i nā papa hana hoʻomaʻemaʻe maʻamau ke pepehi i kēlā me kēia microbe i loaʻa ma luna o ka ʻili, no laila ke koi nui nei ka hoʻomohala ʻana i nā uhi ʻili ʻona ʻole e pale ai i ka ulu ʻana o ka microbial. ma nā ʻili kila kila a me ka plastik i hoʻopā pinepine ʻia a hiki i 72 mau hola, e hōʻike ana i ka pono wikiwiki no nā uhi ʻili me nā waiwai antiviral. Ua hoʻohana ʻia nā ʻaoʻao antimicrobial i nā hoʻonohonoho mālama olakino no nā makahiki he ʻumi, ua hoʻohana ʻia e hoʻomalu i nā maʻi MRSA. Ua ʻimi nui ʻia ka hoʻohana ʻana o ZnO i nā makahiki i hala iho nei ma ke ʻano he mea hoʻoikaika i loko o nā kinikona antimicrobial a me antiviral. Ua ʻike ʻia nā haʻawina ʻona he nui ʻaʻohe mea ʻawaʻawa ʻo ZnO no ke kanaka a me nā holoholona akā he mea maikaʻi loa ia i ka hoʻopau ʻana i nā envelopes kelepona o nā microorganisms. Hoʻokuʻu ʻia nā ion Zn2+ e ka hoʻoheheʻe ʻia ʻana o nā ʻāpana Zinc Oxide e hoʻopau i ka hana antimicrobial hou aʻe i loko o nā microbes ʻē aʻe i loaʻa, a me ka hoʻopili pololei ʻana me nā paia cell a me ka hoʻokuʻu ʻana o nā ʻano oxygen reactive. : nā mea liʻiliʻi liʻiliʻi a me nā mea hoʻonā kiʻekiʻe o ka Zinc nanoparticles ua hoʻonui i ka hana antimicrobial. ʻO nā nanoparticles Zinc Oxide i ʻoi aku ka liʻiliʻi o ka nui e komo maʻalahi i loko o ka membrane cell microbial ma muli o ko lākou ʻāpana interfacial nui. Nui nā haʻawina, ʻoi loa i loko o Sars-CoV-2 i kēia manawa, ua wehewehe i ka hana maikaʻi like e kūʻē i nā maʻi maʻi. he ala no ka hoʻomākaukau wikiwiki ʻana i nā uhi polyurea antimicrobial ma o ka hoʻokomo ʻana i nā ʻāpana nano-Zinc Oxide rare-earth-doped nano-Zinc Oxide i hana ʻia e ka hui ʻana i nā nanoparticles me ka honua laha i loko o ka waikawa nitric. Ua doped nā ZnO nanoparticles me Cerium (Ce), Praseodymium (Pr), Lanthanum ( LA), a me Gadolinium (Gd.) Lanthanum-doped nano-Zinc Oxide particles ua loaʻa he 85% maikaʻi i ka P. aeruginosa a me E. Coli bacterial strains. ʻO kēia mau nanoparticles pū kekahi he 83% maikaʻi i ka pepehi ʻana i nā microbes, ʻoiai ma hope o 25 mau minuke. o ka ʻike ʻana i ke kukui UV. Hiki i nā ʻāpana nano-Zinc Oxide doped i ʻimi ʻia i loko o ke aʻo ʻana ke hōʻike i ka maikaʻi o ka pane kukui UV a me ka pane wela i nā loli wela. Ua hōʻike pū ʻia nā bioassays a me ka hōʻike ʻana i ka ʻili i ka mālama ʻana o nā ʻili i kā lākou mau hana antimicrobial ma hope o ka hoʻohana pinepine ʻana. ʻO ka uhi ʻana o Polyurea he paʻa kiʻekiʻe me ka liʻiliʻi o ka ʻili ʻana i nā ʻili. ʻO ka lōʻihi o nā ʻili i hui pū ʻia me nā hana antimicrobial a me ka pane ʻana o ke kaiapuni o nā ʻāpana nano-ZnO e hāʻawi i ka hoʻomaikaʻi ʻana i ko lākou hiki ke hoʻohana pono i nā ʻano hana like ʻole a me nā ʻoihana. ka lawe ʻana i nā HPAI ma nā wahi mālama ola kino. Loaʻa nō hoʻi ko lākou hoʻohana ʻana i ka ʻoihana meaʻai e hāʻawi i nā ʻāpana antimicrobial a me nā fibers, e hoʻomaikaʻi i ka maikaʻi a me ka mālama ola o nā meaʻai i ka wā e hiki mai ana. ʻOiai ʻo kēia noiʻi ʻana i kona wā kamaliʻi, ʻaʻole kanalua e neʻe koke ʻo ia i waho o ka hale hana a i loko o ka ʻoihana kalepa.
