Copper ndiye chida chothandiza kwambiri cha antimicrobial chapamwamba.
Kwa zaka masauzande ambiri, anthu asanadziwe za majeremusi kapena mavairasi, anthu akhala akudziwa za mphamvu ya mkuwa yopha tizilombo toyambitsa matenda.
Kugwiritsidwa ntchito koyamba kwa mkuwa ngati mankhwala ophera matenda kumachokera ku Smith's Papyrus, chikalata chakale kwambiri chachipatala m'mbiri yonse.
Kumayambiriro kwa zaka za m'ma 1,600 BC, a ku China adagwiritsa ntchito ndalama zamkuwa monga mankhwala ochizira kupweteka kwa mtima ndi m'mimba komanso matenda a chikhodzodzo.
Ndipo mphamvu ya mkuwa imakhalapo. Gulu la Keevil lidayang'ana njanji zakale ku Grand Central Terminal ku New York City zaka zingapo zapitazo. Mkuwawo ukugwirabe ntchito ngati mmene ankachitira tsiku limene anaikidwa zaka 100 zapitazo. "Zinthu izi ndi zolimba ndipo anti-microbial effect sizichoka."
Kodi kwenikweni zimagwira ntchito bwanji?
Mapangidwe a atomiki a Copper amamupatsa mphamvu yowonjezera yopha. Mkuwa uli ndi electron yaulere mu chigoba chake chakunja cha orbital cha ma elekitironi chomwe chimatenga nawo mbali muzochita zochepetsera oxidation (zomwe zimapangitsanso chitsulo kukhala kokondakita wabwino).
Tizilombo tating'onoting'ono tikatera pa mkuwa, ma ion amaphulitsa tizilombo toyambitsa matendawo ngati kuphulitsidwa kwa mivi, kulepheretsa kupuma kwa maselo ndi kuboola mabowo mu membrane wa cell kapena ma virus komanso kupanga ma free radicals omwe amafulumizitsa kupha, makamaka pamalo owuma. Chofunika kwambiri, ma ion amafunafuna ndikuwononga DNA ndi RNA mkati mwa bakiteriya kapena kachilomboka, kuteteza masinthidwe omwe amapanga ma super bugs osamva mankhwala.
Kodi COVID-19 ikhoza kukhalabe ndi moyo pamalo amkuwa?
Kafukufuku watsopano wapeza kuti SARS-CoV-2, kachilombo komwe kamayambitsa mliri wa corona-virus, sipatsirananso ndi mkuwa mkati mwa maola 4, pomwe imatha kukhala papulasitiki kwa maola 72.
Mkuwa uli ndi antimicrobial properties, kutanthauza kuti ukhoza kupha tizilombo toyambitsa matenda monga mabakiteriya ndi mavairasi. Komabe, tizilombo toyambitsa matenda timayenera kukhudzana ndi mkuwa kuti aphedwe. Izi zimatchedwa "kupha munthu."
Ntchito antimicrobial mkuwa:
Chimodzi mwazofunikira kwambiri zamkuwa ndi m'zipatala. Malo owopsa kwambiri m'chipinda chachipatala - njanji za bedi, mabatani oyimbira, mikono yapampando, tebulo la tray, kuyika kwa data, ndi IV pole - ndikusintha ndi zigawo zamkuwa.
Poyerekeza ndi zipinda zopangidwa ndi zipangizo zachikhalidwe, panali kuchepa kwa 83% kwa bakiteriya pazipinda zomwe zili ndi zigawo zamkuwa. Kuphatikiza apo, ziwopsezo za odwala zidachepetsedwa ndi 58%.
Zida zamkuwa zitha kukhala zothandiza ngati malo oletsa tizilombo toyambitsa matenda m'masukulu, mafakitale azakudya, mahotela am'maofesi, malo odyera, mabanki ndi zina zotero.
