Siliva wabwino kwambiri makamaka amapha nyama zosakwatiwa. Siliva-siliva umafanana ndi michere yake ya mankhwala a oxygen kuti igwirizane ndi ma enzymes ndikugunda mabakiteriya matenda a pathogenic. Matupi osiyanasiyana sagwiritsa ntchito mapuloteni opuma.

Siliva pawokha imakhala ndi zoopsa kwambiri kwa thupi la munthu, ngakhale ngati Nano-siliva amatengedwa ndi mankhwala, chifukwa zasiliva ndizochepa (chikwi chimodzi cha mlingo woletsedwa), zimalimbikitsa kwambiri thupi la munthu. Osachepera mu kugwiritsa ntchito vitro si vuto. Komabe, zinthu za zitsulo kapena mankhwala awo nthawi zambiri zimasintha pamlingo wa nanometer.

Siliva wa super-calodial yabwino kwambiri kuposa momwe zilili pamwambapa, kugwiritsa ntchito tinthu tativa tating'onoting'ono tating'onoting'ono, biology, malo ena ndi minda ina imakhala ndi chiyembekezo chochuluka.
