Igolide yeColloidal

Iinanoparticles zegolide zeColloidalziye zasetyenziswa ngabazobi kangangeenkulungwane ngenxa yokuba zinxibelelana nokukhanya okubonakalayo ukuvelisa imibala eqaqambileyo.Kutshanje, le propati ekhethekileyo ye-photoelectric iphandiwe kwaye isetyenziswe kwiinkalo zobuchwepheshe obuphezulu ezifana neeseli ze-solar ze-organic, i-sensor probes, i-arhente zonyango, iinkqubo zokuhanjiswa kweziyobisi kwi-biological and medical applications, i-electronic conductors, kunye ne-catalysis.Iimpawu ze-optical kunye ne-electronic ze-nanoparticles zegolide zinokuhlengahlengiswa ngokutshintsha ubungakanani bazo, imilo, i-surface chemistry kunye ne-aggregation state.

Isisombululo segolide se-colloidal sibhekisela kwi-sol yegolide kunye ne-dispersed phase particle diameter phakathi kwe-1 kunye ne-150 nm.Yinkqubo ye-heterogeneous heterogeneous, kwaye umbala u-orenji ukuya kwimfusa.Ukusetyenziswa kwegolide ye-colloidal njengophawu lwe-immunohistochemistry yaqala ngo-1971. UFaulk et al.Kusetyenziswe i-electron microscopy immunocolloidal gold staining (IGS) ukujonga iSalmonella.

Ibhalwe kwi-antibody yesibini (ihashe elichasayo i-IgG), indlela yegolide engathanga ngqo ye-immunocolloid yasekwa.Ngo-1978, i-geoghega yafumanisa ukusetyenziswa kweziphawuli zegolide ze-colloidal kumgangatho wesipili esikhanyayo.Ukusetyenziswa kwegolide ye-colloidal kwi-immunochemistry ikwabizwa ngokuba yi-immunogold.Emva koko, abaphengululi abaninzi baqinisekisa ukuba igolide ye-colloidal iyakwazi ukubhengeza iiprotheni ngokuzinzileyo kwaye ngokukhawuleza, kwaye umsebenzi we-biological weprotheni awutshintshanga kakhulu.Ingasetyenziselwa ukukhangela indawo echanekileyo yendawo yeseli kunye ne-intracellular polysaccharides, iiprotheni, iipolypeptides, ii-antigens, iihomoni, i-nucleic acids kunye nezinye i-biological macromolecules.Ingasetyenziselwa kwakhona i-immunodiagnosis yemihla ngemihla kunye ne-immunohistochemical localization, ngaloo ndlela ekuxilongweni kweklinikhi Kwaye ukusetyenziswa kokufunyanwa kweziyobisi kunye nezinye iinkalo ziye zaxabiswa ngokubanzi.Okwangoku, i-immunogold staining kwinqanaba le-electron microscope (IGS), i-immunogold staining kwinqanaba le-microscope yokukhanya (IGSS), kunye ne-speckle immunogold staining kwinqanaba le-macroscopic ziya ziba zizixhobo ezinamandla zophando lwezenzululwazi kunye nokuxilongwa kwekliniki.
