AU Zahabu Nanopowders ifite ubuso budasanzwe bwa Plasmon Ibation (LSPR) imiterere ya optique. Iyo imyambaro yoroheje yingufu ni kimwe na electron hejuru yumucera, ubuso bwa electrons mumatsinda. LSPR ntabwo ifitanye isano gusa nibikoresho, ahubwo ifitanye isano gusa, hagati, intera iri hagati yibice, no guhuza ibice. Ubwoko butandukanye nubunini bwa au Nanopowder buzaba bafite impinga itandukanye, mugihe ihindura intera iri hagati yibice, hagati, nibindi kandi bitera kwimura impinga yinjira. Kuri ADN cyangwa izindi bilimenoles kurekura nanoparkicles, kuko Ifu ya 20-30nm ya zahabu ni yo guhitamo neza.

Au zahabu nanopowder hamwe numutungo wa agglomerate biganisha ku kugabanya ibara. Indwara ya zahabu nanopowded hamwe na antibodies kugirango ishyireho ikizamini cya micro-agglutin kugirango itange antigen ihuye. Kimwe na HemagGutination, ibice bikabije birashobora kugaragara nkijisho ryambaye ubusa.
