Zahabu ya colloidal ni ubwoko bwa nanomaterial bukoreshwa cyane mubuhanga bwa immunolabeling.Ikoranabuhanga rya zahabu ya colloidal nubuhanga bukunze gukoreshwa muburyo bwo kuranga ibimenyetso, ubwo ni ubwoko bushya bwubuhanga bwo kuranga immunite bukoresha zahabu ya colloidal nkikimenyetso cya antigen na antibodies, kandi gifite ibyiza byihariye.Mu myaka yashize, yakoreshejwe cyane mubushakashatsi butandukanye bwibinyabuzima.Ubuhanga hafi ya bwose bwa immunoblotting bukoreshwa mumavuriro bukoresha ibimenyetso byabwo.Muri icyo gihe, irashobora gukoreshwa mugutemba, microscopi ya electron, immunologiya, ibinyabuzima bya molekuline ndetse na biochip.

Zahabu ya colloidal yishyuzwa nabi mubidukikije bya alkali, kandi irashobora gushiraho ubumwe bukomeye hamwe nitsinda ryiza rya molekile ya poroteyine.Kuberako ubwo bufatanye ari electrostatike, ntabwo bigira ingaruka kumiterere ya proteine.

Mubyukuri, kuranga zahabu ya colloidal ninzira yo gukwirakwiza poroteyine nizindi macromolecules zandikirwa hejuru ya zahabu ya colloidal.Iyi selile igizwe nubushobozi bukomeye bwo kwamamaza poroteyine kandi irashobora guhuza bidasubirwaho na staphylococcal Poroteyine, immunoglobuline, uburozi, glycoproteine, enzyme, antibiotike, imisemburo, hamwe na serumu albumine polypeptide conjugate.

Usibye guhuza poroteyine, zahabu ya colloidal irashobora kandi guhuza nandi macromolecules yibinyabuzima menshi, nka SPA, PHA, ConA, nibindi. iherekejwe nubudahangarwa nubuzima bwa binder, zahabu ya colloidal ikoreshwa cyane muri immunologiya, histologiya, patologiya na biologiya selile nizindi nzego.
