Mu myaka yashize, inteko ya zahabu ya nanoparticles ya ADN yifashishije ubushakashatsi bwitabiriwe n'abantu benshi, alkane thiol yahinduye oligonucleotide hamwe na nanometero ya zahabu ya covalent ihuza, imiterere nintego ya polynucleotide ikurikirana ya probe ivangavanze, nanoparticles ya zahabu isubiranamo yakusanyirijwe muburyo butangaje, uburyo bwo kwegeranya hamwe numutuku kugeza ubururu, ihinduka ryibara ryibisubizo bivuye muburyo bushya bwa colimetry kugirango tumenye urukurikirane rwa ADN ikurikiranye.Uburyo bufite amahitamo menshi hamwe no kumva neza, kandi burashobora gukoreshwa muguhuza utudomo, kumenya chip hamwe nizindi nzego.

Sisitemu yo gukwirakwiza yakozwe na zahabu nanoparticles mumazi ikunze kwitwa zahabu ya colloidal.

Ibice bya zahabu birashobora guhuzwa neza nitsinda rya amino hamwe na adsorption ya electrostatike idahwitse, bigakora umurongo ukomeye wa AU-S hamwe nitsinda rya sulfhydryl, bigatuma zahabu ya colloidal ishobora guhuzwa na molekile ya bioactive, kandi iperereza ryakozwe rishobora kuba ikoreshwa mugushakisha sisitemu y'ibinyabuzima.

Ifeza ya immunogold na immunogold irangi ukoresheje zahabu ya colloidal nkikimenyetso irashobora gukoreshwa mukirango kimwe cyangwa byinshi, kandi birashobora gukoreshwa mubushakashatsi bwujuje ubuziranenge, bwaho ndetse ndetse nubushakashatsi bwuzuye bwa macromolecules, bwakoreshejwe cyane mubice byinshi byubuvuzi n’ibinyabuzima.

Guangzhou Hongwu Material Technology Co., ltd itanga 99,99% au colloidal zahabu ikwirakwizwa, ubunini bwa 20nm, 100ppm-10000ppm.

Buri cyiciro dutunganya kigaragaza ubwitonzi nubuziranenge byabaye urufatiro rwo gukomeza gukura kwacu.
