Nano antibacterial materials imhando yezvinhu zvitsva zvine antibacterial properties.Mushure mekubuda kwenanotechnology, antibacterial agents anogadzirirwa kuita nano-scale antibacterial agents kuburikidza nedzimwe nzira uye matekiniki, obva agadzirirwa nemamwe maantibacterial vatakuri mune chinhu chine antibacterial properties.

Classification ye nano antibacterial zvinhu

1. Metal nano antibacterial zvinhu

Ioni dzesimbi dzinoshandiswa mune inorganic nano antibacterial zvinhu zvirisirivheri, mhangura, zincuye zvakafanana izvo zvakachengeteka kumuviri wemunhu.
Ag + ine chepfu kune prokaryotes (mabhakitiriya) uye haina chepfu mhedzisiro pamasero eukaryotic.Kugona kwayo kweantibacterial ndiko kwakasimba pakati peakawanda simbi ayoni anogona kushandiswa zvakachengeteka.Nano sirivheri ine simba rekuuraya rakasimba pane akasiyana mabhakitiriya.Nekuda kweiyo isiri-chepfu, yakakura-spectrum uye yakanaka antibacterial zvivakwa, nano sirivheri-yakavakirwa inorganic antibacterial zvinhu parizvino inotonga inorganic antibacterial zvinhu uye inoshandiswa zvakanyanya muzvigadzirwa zvekurapa, machira ehurumende uye midziyo yemumba.

2. Photocatalytic nano antibacterial zvinhu
Photocatalytic nano antibacterial zvinhu zvinoreva kirasi ye semiconductor inorganic zvinhu zvinomiririrwa nano-TiO2, iyo ine photocatalytic zvimiro, senge nano-TiO2, ZnO, WO3, ZrO2, V2O3,SnO2, SiC, uye zvikamu zvavo.Panyaya yemaitiro uye mutengo wekuita, nano-TiO2 ine mabhenefiti makuru pane akati wandei mamwe photocatalytic antibacterial zvinhu: nano-TiO2 haigone kungokanganisa fecundity yebhakitiriya, asi zvakare kurwisa chikamu chekunze chemasero ebhakitiriya, kupinda mukati me membrane, kushatisa zvachose mabhakitiriya, uye kudzivirira kusvibiswa kwechipiri kunokonzerwa ne endotoxin.

3. Inorganic nano antibacterial materials yakagadziridzwa ne quaternary ammonium salt

Zvinhu zvakadai zveantibacterial zvinowanzoshandiswa mune yakabatana nano-antibacterial zvinhu montmorillonite, nano-antibacterial zvinhu nano-SiO2 zvimedu zvine maitiro akabatanidzwa.Inorganic nano-SiO2 zvimedu zvinoshandiswa sechikamu chedoping mumapurasitiki, uye hazvisi nyore kutamiswa uye kunyungudutswa nekuputirwa nepurasitiki, kuitira kuti antibacterial plastiki ive yakanaka uye yenguva refu inorwisa mabhakitiriya.

4. Composite nano antibacterial zvinhu
Parizvino, zvinhu zvakawanda zvenano-antibacterial zvinoshandisa imwe nano-antibacterial material, iyo ine zvimwe zvisingakwanisi.Naizvozvo, kugadzira nekugadzira rudzi rutsva rwemishonga inorwisa mabhakitiriya nekukurumidza uye inobudirira sterilization basa rave danho rakakosha rekutsvaga kwazvino kwekuwedzera kwenanotechnology.

Main application minda ye nano antibacterial zvinhu
1. Nano antibacterial coating
2. Nano antibacterial plastiki
3. Nano antibacterial fiber
4. Nano antibacterial ceramics
5. Nano antibacterial building materials

Nano antibacterial zvinhu zvine zvakawanda zvakanakisa zvinhu zvakasiyana kubva kune macroscopic composite zvinhu, senge yakakwira kupisa kupisa, nyore kushandisa, yakagadzika makemikari zvivakwa, inogara kwenguva refu inorwisa mabhakitiriya spectrum uye chengetedzo, ichiita nano antibacterial zvinhu zvinonyanya kushandiswa mukuvaka, ceramics, anitary ware, machira, mapurasitiki nemimwe minda yakawanda.Zvinotendwa kuti nekudzika kwekutsvagisa kwesainzi, nano-antibacterial zvinhu zvichange zvichiwedzera kukosha mundima dzakasiyana semushonga, kushandiswa kwemazuva ese, indasitiri yemakemikari uye zvekuvaka.
