Au Gold nanopowders suna da kaddarorin gani na gani na plasmon ibration (LSPR).Lokacin da mitar makamashin hasken da ya faru ya yi daidai da na'urorin lantarki a saman ɓangarorin shinkafar, rukunin electrons na saman rukuni.LSPR ba wai kawai yana da alaƙa da kayan ba, har ma da siffa, matsakaicin kewaye, nisa tsakanin ɓangarorin, da daidaitawar barbashi.Daban-daban iri da masu girma dabam na Au nanopowder za su sami daban-daban sha kololuwa, yayin da canza nisa tsakanin barbashi, matsakaici, da dai sauransu da kuma haifar da kaura daga sha kololuwa.Don DNA ko wasu kwayoyin halitta don nisa da nanoparticles, don 20-30nm zinariya nano foda shine mafi kyawun zaɓi.

Au zinariya nanopowder tare da dukiyar agglomerate yana haifar da raguwar launi.Ana haɗe nanopowders na zinariya tare da ƙwayoyin rigakafi don kafa gwajin micro-agglutination don gano antigen daidai.Kamar hemagglutination kai tsaye, ana iya lura da ƙwayoyin agglomerated tare da ido tsirara.
