Colloidal goridhe imhando yemananomaterial inoshandiswa zvakanyanya mu immunolabeling tekinoroji.Colloidal goridhe tekinoroji inowanzoshandiswa kunyora tekinoroji, inova rudzi rutsva rwehunyanzvi hwekunemba tekinoroji inoshandisa goridhe recolloidal setracer marker yemaantigen uye masoja ekudzivirira chirwere, uye ine zvayakanakira.Mumakore achangopfuura, yakashandiswa zvakanyanya mukutsvaga kwakasiyana-siyana kwebiology.Anenge ese ma immunoblotting maitiro anoshandiswa mukiriniki anoshandisa mamaki ayo.Panguva imwecheteyo, inogona kushandiswa mukuyerera, electron microscopy, immunology, molecular biology uye kunyange biochip.

Colloidal goridhe inobhadhariswa zvisina kunaka munzvimbo isina simba alkali, uye inogona kuumba chisungo chakasimba nemapoka anochajiswa zvakanaka emapuroteni mamorekuru.Nekuti chisungo ichi chiri electrostatic bond, hachikanganise zvipenyu zveprotein.

Muchidimbu, kuiswa kwegoridhe colloidal ndiyo nzira yekuisa mukati umo mapuroteni uye mamwe macromolecules anoiswa pamusoro peiyo colloidal goridhe zvimedu.Iyi spherical particle ine simba rakasimba rekudsorb mapuroteni uye inogona kusunga isina-covalently kune staphylococcal A protein, immunoglobulin, toxin, glycoprotein, enzyme, antibiotic, hormone, uye bovine serum albumin polypeptide conjugates.

Pamusoro pekusunga mapuroteni, colloidal goridhe inogonawo kusunga kune mamwe akawanda biological macromolecules, senge SPA, PHA, ConA, etc. Zvinoenderana nezvimwe zvemuviri zvimiro zvecolloidal goridhe, senge yakakwira maelectron density, particle size, shape and color reaction, zvakasanganiswa nekudzivirira uye zvipenyu zvimiro zvebinder, colloidal goridhe rinoshandiswa zvakanyanya muimmunology, histology, pathology uye cell biology uye mamwe minda.
