Gold colloidal

Colloidal ọla edo nanoparticlesejirila ndị na-ese ihe mee ihe ruo ọtụtụ narị afọ n'ihi na ha na-emekọ ihe na ìhè a na-ahụ anya iji mepụta agba na-egbuke egbuke.N'oge na-adịbeghị anya, a na-enyocha ihe onwunwe fotoelectric pụrụ iche a ma tinye ya n'ọrụ na nkà na ụzụ dị elu dị ka mkpụrụ ndụ anyanwụ nke organic, sensọ nyocha, ndị na-ahụ maka ọgwụgwọ, usoro nnyefe ọgwụ na ngwa nje na ọgwụ, ndị na-eduzi eletrọnịkị, na catalysis.Enwere ike imezi ihe anya na eletrọnịkị nke ọla edo nanoparticles site n'ịgbanwe nha ha, ọdịdị ha, kemistri elu na steeti mkpokọta.

Ihe ngwọta ọla edo nke colloidal na-ezo aka na ọla edo ọla edo nke nwere dayameta akụkụ akụkụ nke gbasasịrị n'etiti 1 na 150 nm.Ọ bụ nke sistemu heterogeneous heterogeneous, na agba bụ oroma ka odo odo.Ojiji nke colloidal gold dị ka akara maka immunohistochemistry malitere na 1971.

Edebere ya na mgbochi nke abụọ (ịnyịnya mgbochi mmadụ IgG), e hibere usoro ntụpọ ọla edo na-apụtachaghị ìhè.N'afọ 1978, geoghega chọpụtara ngwa nrịbama ọla edo colloidal na ọkwa enyo ọkụ.Ngwa nke colloidal gold na immunochemistry ka a na-akpọkwa immunogold.Mgbe nke ahụ gasịrị, ọtụtụ ndị ọkà mmụta kwusiri ike na ọla edo colloidal nwere ike ime ka protein guzosie ike na ngwa ngwa, na ọrụ ndụ nke protein agbanwebeghị nke ukwuu.Enwere ike iji ya dị ka nyocha maka nhazi nke ọma nke elu cell na polysaccharides intracellular, protein, polypeptides, antigens, hormones, nucleic acid na ihe ndị ọzọ dị ndụ macromolecules.A pụkwara iji ya mee ihe maka immunodiagnosis kwa ụbọchị na immunohistochemical localization, ya mere na nyocha ụlọ ọgwụ Na ntinye nke nchọpụta ọgwụ na akụkụ ndị ọzọ ejirila kpọrọ ihe.Ka ọ dị ugbu a, ntụpọ immunogold na ọkwa elektrọn microscope (IGS), ntụpọ immunogold na ọkwa microscope ìhè (IGSS), na ntụpọ speckle immunogold na ọkwa macroscopic na-aghọwanye ngwa ọrụ siri ike maka nyocha sayensị na nyocha ụlọ ọgwụ.
