Nano siliva ndi chinthu chosavuta cha siliva wachitsulo chokhala ndi nanometer kukula.Ambiri mwa ma nanoparticles asiliva ali mozungulira ma nanometers 25 mu kukula, ndipo ali ndi mphamvu zoletsa komanso kupha tizilombo toyambitsa matenda monga Escherichia coli, Neisseria gonorrhoeae ndi Chlamydia trachomatis.Ndipo sipadzakhala kukana mankhwala.Masokiti a thonje opangidwa ndi siliva wa nano ndi ulusi wa thonje wophatikizika amakhala ndi antibacterial ndi deodorizing effect.

Siliva ya Nano imakhala ndi zotsatira zabwino za bactericidal kwa nthawi yaitali ndipo imagwiritsidwa ntchito kwambiri m'mafakitale antibacterial.Pa nthawi yomweyo, ufa wa siliva wa nano uli ndi ntchito zapamwamba komanso zothandizira, ndipo zimagwiritsidwa ntchito kwambiri muzothandizira.
