Mamwe masimbi, akadaisirivheri, goridhe nemhangura, zvine antibacterial uye antimicrobial properties;vanokwanisa kuuraya kana kudzikamisa kukura kwetwupukanana pasina kukanganisa zvakanyanya mugamuchiri.Kunamatira mhangura, yakachipa pavatatu ava, kuzvipfeko kwakaratidza kunetsa munguva yakapfuura.Asi muna 2018, vaongorori kubva kuYunivhesiti yeManchester neNorthwest Minzu neSouthwest University kuChina vakabatana kugadzira yakasarudzika nzira inopfekedza jira nemhangura nanoparticles.Machira aya anogona kushandiswa seyunifomu yechipatara inorwisa utachiona kana mamwe machira ekushandisa pakurapa.

“Zvabuda izvi zvakanaka chose, uye mamwe makambani ari kutoratidza kufarira kugadzira michina iyi.Tinovimba tinogona kutengeserana tekinoroji yepamusoro mukati memakore akati wandei.Isu takatanga kushanda mukudzikisa mutengo uye kuita kuti hurongwa huve nyore," Munyori Mukuru Dr. Xuqing Liuakadaro.

Munguva yechidzidzo ichi, copper nanoparticles yakaiswa kudonje nepolyester kuburikidza nemaitiro anonzi, "Polymer Surface Grafting."Iyo nanoparticles yemhangura yepakati pe1-100 nanometers yakanamirwa kune zvigadzirwa uchishandisa polymer bhurashi.A polymer bhurashi igungano remacromolecules (mamorekuru ane maatomu akawanda) akasungirirwa kune rumwe rutivi kune substrate kana pamusoro.Iyi nzira yakagadzira chisungo chakasimba chemakemikari pakati pemhangura nanoparticles nenzvimbo dzemachira.

"Zvakaonekwa kuti mhangura nanoparticles dzaive dzakafanana uye dzakagovaniswa zvakasimba panzvimbo," maererano nekudzidza.abstract.Zvinhu zvakarapwa zvakaratidza "inoshanda antibacterial chiitiko" kurwisa Staphylococcus aureus (S. aureus) uye Escherichia coli (E. coli).Iwo machira matsva akaumbwa aya akagadzirwa nesainzi ane simba uye anogona kugezeka - achiri kuratidzaantibacterialkurwisa basa mushure mekugeza makumi matatu.

"Izvozvi izvo zvinhu zvedu zvakaumbwa zvinopa antibacterial zvimiro uye kusimba, zvine mukana wakakura wemashandisirwo emazuva ano ekurapa nehutano," akadaro Liu.

Utachiona hwemabhakitiriya injodzi huru yehutano pasi rose.Vanogona kupararira pazvipfeko nepamusoro mukati mezvipatara, zvichidhura makumi ezviuru zvehupenyu uye mabhiriyoni emadhora pagore muUS chete.

Gregory Grass weYunivhesiti yeNebraska-Lincoln aneakadzidzamhangura yakaoma kugona kuuraya utachiona pakubata pamusoro.Kunyange achifunga kuti nzvimbo dzemhangura hadzigone kutsiva dzimwe nzira dzekuchengetedza hutsanana munzvimbo dzekurapa, anofunga kuti "zvichadzikisira mutengo une chekuita nehutachiona hwechipatara uye kudzivirira hosha yevanhu, pamwe nekuponesa hupenyu."

Simbi dzakashandiswa seantimicrobial agentskwezviuru zvemakore uye yakatsiviwa nemishonga inorwisa mabhakitiriya pakati pe-20th century.Muna 2017bepayakanzi, "Metal-based antimicrobial strategy," Raymond Turner weYunivhesiti yeCalgary anonyora, "Nepo tsvakurudzo kusvika nhasi pamusoro peMBAs ([metal-based antimicrobials]) ine vimbiso yakawanda, kunzwisisa kwetoxicologyzvemasimbi aya pavanhu, zvipfuyo, zvirimwa uye utachiona husina kusimba zvachose.”
