Auro Colloidal

Nanoparticles auro Colloidalua fa'aaogaina e le au tusiata mo le tele o seneturi aua latou te fegalegaleai ma le malamalama vaaia e maua ai lanu susulu.Talu ai nei, o lenei mea faʻapitoa photoelectric ua suʻesuʻeina ma faʻaogaina i matata faʻatekonolosi e pei o sela o le la, suʻesuʻega faʻalogo, vailaʻau faʻamaʻi, faiga e tuʻuina atu ai vailaʻau i mea ola ma fomaʻi, taʻavale eletise, ma catalysis.O mea fa'apitoa ma fa'aeletoroni o nanoparticles auro e mafai ona fetu'una'i e ala i le suia o latou lapo'a, foliga, kemisi luga ma le tu'ufa'atasiga.

O le vaifofo auro colloidal e fa'atatau i se sol auro ma se vaega ta'ape vaega ta'amilosaga i le va o le 1 ma le 150 nm.E a'afia i se faiga fa'afetetele, ma o le lanu e moli i le lanu viole.O le fa'aogaina o le auro colloidal e fai ma fa'ailoga mo le immunohistochemistry na amata ile 1971. Faulk et al.Fa'aaogā le fa'aeletonika microscopy immunocolloidal staining auro (IGS) e mata'ituina ai Salmonella.

Fa'ailogaina ile antibody lona lua (horse anti-human IgG), na fa'atūina ai se auala e fa'ailoga auro ai le immunocolloid.I le 1978, na maua ai e geoghega le faʻaogaina o faʻailoga auro colloidal i le faʻata malamalama.O le faʻaaogaina o auro colloidal i le immunochemistry e taʻua foi o le immunogold.Mulimuli ane, na faʻamaonia atili e le toʻatele o tagata atamamai e mafai e le auro colloidal ona faʻapipiʻi faʻamalosi polotini ma le vave, ma e leʻi suia tele le gaioiga o meaola o le polotini.E mafai ona faʻaaogaina e fai ma suʻesuʻega mo le faʻatulagaina saʻo o le cell surface ma intracellular polysaccharides, proteins, polypeptides, antigens, hormones, nucleic acids ma isi macromolecules biological.E mafai foi ona faʻaaogaina mo le immunodiagnosis i aso uma ma le immunohistochemical localization, faʻapea i le suʻesuʻega falemaʻi Ma o le faʻaogaina o fualaau faʻasaina ma isi vaega ua faʻatauaina lautele.I le taimi nei, o le fa'ailoga o le immunogold i le electron microscope level (IGS), immunogold staining i le malamalama microscope level (IGSS), ma speckle immunogold staining i le macroscopic tulaga ua fa'atupula'ia avea ma meafaigaluega mamana mo su'esu'ega fa'asaienisi ma su'esu'ega falema'i.
