Inzahabu

Colloidal zahabu nanoparticleszakoreshejwe nabahanzi mu binyejana byinshi kuko zikorana numucyo ugaragara kugirango zitange amabara meza.Vuba aha, uyu mutungo udasanzwe w’amashanyarazi wakozweho ubushakashatsi kandi ushyirwa mubikorwa byubuhanga buhanitse nkingirabuzimafatizo zikomoka ku mirasire y'izuba, sensor probe, imiti ivura, uburyo bwo gutanga ibiyobyabwenge mubinyabuzima ndetse nubuvuzi, imiyoboro ya elegitoroniki, na catalizike.Ibikoresho bya optique na elegitoronike ya zahabu nanoparticles irashobora guhindurwa muguhindura ingano, imiterere, chimie yubutaka hamwe nuburyo bwo kwegeranya.

Umuti wa zahabu wa colloidal bivuga zahabu ya sol hamwe na diameter yatandukanijwe hagati ya 1 na 150 nm.Nibintu bya heterogeneous sisitemu itandukanye, kandi ibara ni orange kumururu.Ikoreshwa rya zahabu ya colloidal nk'ikimenyetso cya immunohistochemie yatangiye mu 1971. Faulk n'abandi.Ikoreshwa rya electron microscopi immunocolloidal zahabu irangi (IGS) kugirango urebe Salmonella.

Ikimenyetso cya antibody ya kabiri (ifarashi irwanya abantu IgG), hashyizweho uburyo bwo kwanduza zahabu immunocolloid itaziguye.Mu 1978, geoghega yavumbuye ikoreshwa rya zahabu ya colloidal kurwego rwindorerwamo.Gukoresha zahabu ya colloidal muri immunochemie nayo yitwa immunogold.Nyuma yaho, intiti nyinshi zemeje kandi ko zahabu ya colloidal ishobora kwamamaza poroteyine mu buryo bwihuse kandi vuba, kandi ibikorwa by’ibinyabuzima bya poroteyine ntabwo byahindutse ku buryo bugaragara.Irashobora gukoreshwa nkubushakashatsi bwerekana neza neza ubuso bwimiterere ya selile na polysaccharide yo mu nda, proteyine, polypeptide, antigene, imisemburo, acide nucleic nibindi macromolecules.Irashobora kandi gukoreshwa mugukingira indwara ya buri munsi no gukingira immunohistochemicale, bityo mugupima kwa muganga Kandi ikoreshwa ryokumenya ibiyobyabwenge nibindi bintu byahawe agaciro gakomeye.Kugeza ubu, immunogold irangi kurwego rwa electron microscope (IGS), immunogold yanduza urwego rwa microscope yoroheje (IGSS), hamwe na immunogold yanduye ku rwego rwa macroscopique biragenda biba ibikoresho bikomeye mubushakashatsi bwa siyansi no gusuzuma indwara.
