Nano antibacterial materials ndi mtundu wa zipangizo zatsopano zokhala ndi antibacterial properties.Pambuyo pakuwonekera kwa nanotechnology, ma antibacterial agents amakonzedwa kukhala nano-scale antibacterial agents kudzera munjira ndi njira zina, kenako amakonzedwa ndi zonyamula antibacterial kukhala chinthu chokhala ndi antibacterial properties.

Gulu la nano antibacterial materials

1. Metal nano antibacterial zipangizo

Ma ayoni achitsulo omwe amagwiritsidwa ntchito muzinthu zamtundu wa nano antibacterial ndi siliva, mkuwa, zinki ndi zina zomwe zili zotetezeka mthupi la munthu.
Ag + ndi poizoni ku prokaryotes (mabakiteriya) ndipo alibe zotsatira za poizoni pa maselo a eukaryotic.Mphamvu yake ya antibacterial ndi yamphamvu kwambiri pakati pa ayoni angapo achitsulo omwe angagwiritsidwe ntchito bwino.Nano silivaali ndi mphamvu kupha mabakiteriya osiyanasiyana.Chifukwa chosakhala ndi poizoni, sipekitiramu yotakata komanso ma antibacterial abwino, zida za nano siliva zochokera ku inorganic antibacterial pakali pano zimayang'anira zida za antibacterial ndipo zimagwiritsidwa ntchito kwambiri muzamankhwala, nsalu zaboma komanso zida zapanyumba.

2. Photocatalytic nano antibacterial zipangizo
Photocatalytic nano antibacterial materials amatanthauza gulu la semiconductor inorganic materials oimiridwa ndi nano-TiO2 (titaniyamu dioxide nanoparticles), yomwe ili ndi zinthu za photocatalytic, monga nano-TiO2, ZnO (zinc oxide nanoparticles), WO3(Tungsten oxide nanoparticlesZrO2 (zirconium dioxide nanoparticles), V2O3(vanadium oxide nanoparticles), SnO2(tin oxide nanoparticles, SiC (silicon carbide nanoparticles), ndi zolemba zawo.Pankhani ya njira ndi magwiridwe antchito, nano-TiO2 ili ndi zabwino zambiri kuposa zida zina zingapo za antibacterial photocatalytic: nano-TiO2 sizingakhudze kukula kwa bakiteriya, komanso kuukira wosanjikiza wakunja wa ma cell a bakiteriya, kulowa mu cell membrane, kusokoneza kwathunthu mabakiteriya, ndikuteteza kuipitsidwa kwachiwiri komwe kumachitika chifukwa cha endotoxin.

3. Inorganic nano antibacterial zipangizo kusinthidwa ndi quaternary ammonium mchere

Zinthu zotsutsana ndi mabakiteriya zoterezi zimagwiritsidwa ntchito kwambiri muzinthu zosakanikirana za nano-antibacterial montmorillonite, nano-antibacterial material nano-SiO2 particles (silicon dioxide nanoparticles) yokhala ndi mawonekedwe omezanitsidwa.Tinthu tating'onoting'ono ta nano-SiO2 timagwiritsidwa ntchito ngati gawo la doping m'mapulasitiki, ndipo sizimasamuka mosavuta ndikumangika ndi pulasitiki, kotero kuti pulasitiki ya antibacterial imakhala ndi antibacterial yabwino komanso yayitali.

4. Zophatikizika za nano antibacterial
Pakalipano, zipangizo zambiri za nano-antibacterial zimagwiritsa ntchito mankhwala amodzi a nano-antibacterial, omwe ali ndi malire.Choncho, kupanga ndi kupanga mtundu watsopano wa zipangizo zowononga tizilombo toyambitsa matenda mofulumira komanso mogwira mtima ntchito yoletsa kubereka kwakhala njira yofunikira pa kafukufuku wamakono wa kukulitsa kwa nanotechnology.

Main ntchito minda ya nano antibacterial zipangizo
1. Nano antibacterial zokutira
2. Nano antibacterial pulasitiki
3. Nano antibacterial fiber
4. Nano antibacterial ceramics
5. Nano antibacterial zomangira

Nano antibacterial zipangizo zili ndi zinthu zambiri zabwino kwambiri zosiyana ndi macroscopic zipangizo composite, monga mkulu kutentha kukana, yosavuta kugwiritsa ntchito, khola mankhwala katundu, yaitali antibacterial sipekitiramu ndi chitetezo, kupanga nano antibacterial zipangizo chimagwiritsidwa ntchito kwambiri mu zomangira, ceramics, anitary ware, nsalu, mapulasitiki ndi minda ina yambiri.Amakhulupirira kuti pakuzama kwa kafukufuku wa sayansi, zida za nano-antibacterial zitha kugwira ntchito yofunika kwambiri m'magawo osiyanasiyana monga mankhwala, kugwiritsa ntchito tsiku ndi tsiku, makampani opanga mankhwala ndi zida zomangira.
