Zitsulo zina, mongasiliva, golidi ndi mkuwa, ali ndi antibacterial ndi antimicrobial properties;amatha kupha kapena kuchepetsa kukula kwa tizilombo tating'onoting'ono popanda kukhudza kwambiri gulu.Kumamatira mkuwa, wotchipa kwambiri mwa atatuwo, ku zovala kwakhala kovuta m'mbuyomu.Koma mu 2018, ofufuza ochokera ku The University of Manchester ndi Northwest Minzu ndi Southwest University ku China adagwirizana kuti apange njira yapadera yomwe imavala bwino nsalu ndi nanoparticles zamkuwa.Nsaluzi zitha kugwiritsidwa ntchito ngati yunifolomu yakuchipatala yolimbana ndi tizilombo toyambitsa matenda kapena nsalu zina zamankhwala.

"Zotsatirazi ndi zabwino kwambiri, ndipo makampani ena akuwonetsa kale chidwi chofuna kupanga ukadaulo uwu.Tikukhulupirira kuti titha kugulitsa ukadaulo wapamwamba pazaka zingapo.Tsopano tayamba kuyesetsa kuchepetsa ndalama komanso kuti ntchitoyi ikhale yosavuta,” Dr. Xuqing Liuadatero.

Pa kafukufukuyu, ma nanoparticles amkuwa adagwiritsidwa ntchito ku thonje ndi poliyesitala kudzera munjira yotchedwa, "Polymer Surface Grafting."Ma nanoparticles amkuwa apakati pa 1-100 nanometers adalumikizidwa kuzinthuzo pogwiritsa ntchito burashi ya polima.Burashi ya polima ndi gulu la ma macromolecules (mamolekyu okhala ndi ma atomu ambiri) omwe amamangiriridwa kumapeto kwina kupita ku gawo lapansi kapena pamwamba.Njirayi inapanga mgwirizano wamphamvu wa mankhwala pakati pa nanoparticles zamkuwa ndi nsalu za nsalu.

"Zinapezeka kuti ma nanoparticles amkuwa anali ofanana komanso amagawidwa mwamphamvu pamtunda," malinga ndi kafukufukuyu.mwatsatanetsatane.Zida zothandizira zidawonetsa "ntchito yabwino ya antibacterial" motsutsana ndi Staphylococcus aureus (S. aureus) ndi Escherichia coli (E. coli).Nsalu zatsopano zophatikizika zomwe asayansi apangazi ndizolimba komanso zotha kuchapa - adawonetsabeantibacterialkusagwira ntchito pambuyo posamba 30.

"Tsopano popeza zida zathu zophatikizika zili ndi zida zabwino kwambiri zolimbana ndi mabakiteriya komanso kulimba, zili ndi kuthekera kwakukulu pakugwiritsa ntchito chithandizo chamankhwala chamakono," adatero Liu.

Matenda oyambitsidwa ndi mabakiteriya ndiwowopsa padziko lonse lapansi.Amatha kufalikira pazovala ndi malo mkati mwa zipatala, zomwe zimawononga miyoyo masauzande ndi mabiliyoni a madola pachaka ku US kokha.

Gregory Grass waku Yunivesite ya Nebraska-Lincoln ali ndianaphunziraKutha kwa mkuwa wouma kupha tizilombo toyambitsa matenda tikakhudza pamwamba.Ngakhale akuganiza kuti malo amkuwa sangalowe m'malo mwa njira zina zofunika zotetezera ukhondo m'zipatala, akuganiza kuti "zichepetsa mtengo wokhudzana ndi matenda obwera m'chipatala ndikuchepetsa matenda a anthu, komanso kupulumutsa miyoyo."

Zitsulo zakhala zikugwiritsidwa ntchito ngatimankhwala antimicrobialkwa zaka masauzande ambiri ndipo adasinthidwa ndi maantibayotiki apakati pazaka za m'ma 20.Mu 2017pepalalotchedwa, “Metal-based antimicrobial strategy,” Raymond Turner wa pa yunivesite ya Calgary analemba kuti, “Ngakhale kuti kafukufuku wokhudza MBAs ([metal-based antimicrobial]) ali ndi lonjezo lalikulu, kumvetsetsa kwatoxicologymwa zitsulo zimenezi pa anthu, ziweto, mbewu ndi tizilombo tating’onoting’ono tambiri tikusowa.”
