Colloidal gold

Colloidal goridhe nanoparticleszvave zvichishandiswa nenyanzvi kwemazana emakore nokuti zvinopindirana nechiedza chinooneka kuti zvibudise mavara akajeka.Nguva pfupi yadarika, iyi yakasarudzika photoelectric pfuma yakatsvagirwa uye yakashandiswa mumhando yepamusoro-tech minda senge organic solar maseru, sensor probes, vamiririri vekurapa, madhipatimendi ekuunza zvinodhaka mune biological uye zvekurapa zvikumbiro, emagetsi conductor, uye catalysis.Iyo yemaziso uye yemagetsi zvimiro zvegoridhe nanoparticles zvinogona kugadziridzwa nekuchinja saizi yavo, chimiro, yepamusoro chemistry uye aggregation mamiriro.

Iyo colloidal goridhe mhinduro inoreva goridhe sol ine yakapararira chikamu chechidimbu dhayamita pakati pe1 ne150 nm.Iyo ndeye heterogeneous heterogeneous system, uye ruvara rweorenji kune rwepepuru.Kushandiswa kwegoridhe colloidal sechiratidzo che immunohistochemistry kwakatanga muna 1971. Faulk et al.Inoshandiswa erekitironi microscopy immunocolloidal gold staining (IGS) kuona Salmonella.

Yakanyorwa pane yechipiri antibody (bhiza anti-human IgG), nzira isina kunanga immunocolloid goridhe staining yakamiswa.Muna 1978, geoghega akawana mashandisirwo emakaka egoridhe ecolloidal padanho regirazi.Iko kushandiswa kwegoridhe colloidal mu immunochemistry kunonzi zvakare immunogold.Mushure mezvo, nyanzvi dzakawanda dzakasimbisa zvakare kuti colloidal goridhe inogona kushambadza mapuroteni zvakatsiga uye nekukurumidza, uye biological chiitiko cheprotein haina kuchinja zvakanyanya.Inogona kushandiswa se probe yekunyatsomira kwesero pamusoro uye intracellular polysaccharides, mapuroteni, polypeptides, maantigen, mahormone, nucleic acids uye mamwe biological macromolecules.Inogonawo kushandiswa kwezuva nezuva immunodiagnosis uye immunohistochemical localization, nokudaro mukuongororwa kwekliniki Uye kushandiswa kwekutsvaga zvinodhaka nezvimwe zvinhu zvakave zvakakosha zvikuru.Parizvino, immunogold staining at the electron microscope level (IGS), immunogold staining at light microscope level (IGSS), uye speckle immunogold staining at the macroscopic level ari kuwedzera kuve maturusi ane simba ekutsvagisa kwesainzi uye kuongororwa kwekiriniki.
