Au Gold nanopowders waxay leeyihiin sifooyin muuqaal ah oo plasmon ibration (LSPR).Marka dhacdadu inta jeer ee tamarta iftiinka ay la mid tahay elektaroonnada dusha sare ee qaybaha bariiska, kooxda elektarooniga ah ee korka ayaa dhawaaqa.LSPR kuma xidhna oo keliya alaabta, laakiin sidoo kale waxay la xidhiidhaa qaabka, dhex dhexaadnimada ku xeeran, masaafada u dhaxaysa qaybaha, iyo summaynta qaybaha.Noocyada kala duwan iyo cabbirrada Au nanopowder waxay yeelan doonaan nuugitaanno kala duwan, iyadoo beddeleysa masaafada u dhexeysa walxaha, dhexdhexaadka, iwm.DNA ama biomolecules kale si ay u fogeeyaan nanoparticles, 20-30nm dahab nano budada ayaa ah doorashada ugu fiican.

Au gold nanopowder oo leh hantida agglomerate waxay keenaysaa dhimista midabka.Nanopowders-ka dahabiga ah waxaa lagu daraa unugyada difaaca si loo sameeyo baaritaanka micro-agglutination si loo ogaado antigen-ka u dhigma.Sida hemagglutination aan toos ahayn, qaybaha agglomerated ayaa si toos ah loogu arki karaa isha qaawan.
