1. Kev npaj iav: xaiv iav nrog lub teeb pom kev zoo. Ntxuav thiab qhuav lub khob kom huv si thiab qhuav.
2. Membrane Material Preparation: Feem ntau, cov ntaub ntawv xws li nano-silver thiab nano-titanium dioxide yog siv, npaj los ntawm cov txheej txheem xws li sol-gel method thiab vapor deposition.
3. Txheej: Siv lub cev txheej txheej txheej txheem, cov khoom siv membrane yog uniformly coated mus rau lub iav nto los ua ib tug antibacterial zaj duab xis.
4. Kev ci: Cov qauv iav coated tau muab tso rau hauv lub tshuab desiccator kom qhuav thiab ci kom ntseeg tau tias cov khoom siv membrane ruaj khov rau hauv cov iav nto.
5. Kev sim: Siv cov kab lis kev cai cov tais diav thiab cov tshuaj tua kab mob, cov kab mob sib txawv yog coated rau ntawm cov qauv saum npoo thiab incubated nyob rau hauv lub incubator rau ib lub sij hawm ntawm kev soj ntsuam cov nyhuv antibacterial.
