Ifeza nziza-nziza cyane yica ibinyabuzima. Nano-feza yamenetse hamwe na ogisijeni ya ogisijeni enzymes kugirango idakora imisemburo na ihumeka ya bagiteri ya pathogenic. Imibiri myinshi ntabwo ikoresha kuri protee kugirango ihumeke.

Ifeza ubwayo ifite uburozi buke cyane kumubiri wumuntu, nubwo nano-feza ijyanwaho imbere nkibiyobyabwenge, kuko ibirimo bya feza ari nto (igihumbi cyibipimo byihanganira), ntabwo bigira ingaruka nke kumubiri wumuntu. Byibuze muri vitro gukoresha ntakibazo. Ariko, imiterere yibyuma cyangwa ibice byabo mubisanzwe bihinduka kurwego rwa Nanometer.

Ifeza nziza-nziza ya feza ifite ibintu byinshi byavuzwe haruguru, gushyira mu bikorwa ibice bya nano-feza mu buvuzi, biologiya, ibinyabuzima, ibidukikije n'ibindi bibanza bizagira ibyiringiro byinshi byo gutera imbere.
