M'zaka zaposachedwapa, golide nanoparticles msonkhano wa DNA mkhalapakati kafukufuku ambiri chidwi, alkane thiol kusinthidwa oligonucleotides ndi nanometer golide covalent chomangira, mawonekedwe ndi cholinga polynucleotide sequence probe hybridization, reversible golide nanoparticles anasonkhanitsidwa mu supramolecular dongosolo, kudzikundikira ndondomeko ndi wofiira kwa buluu, kusintha kwa mtundu wa zotsatira kumachokera njira yatsopano colorimetry kuti azindikire backlog DNA sequence.The njira ali high selectivity ndi tilinazo zabwino, ndipo angagwiritsidwe ntchito madontho hybridization, chip kuzindikira ndi madera ena.

Njira yobalalika yopangidwa ndi nanoparticles ya golide m'madzi imadziwika kuti colloidal gold.

Tinthu tating'ono ting'onoting'ono ta golide tating'onoting'ono tating'onoting'ono ta amino ndi osagwirizana ndi ma electrostatic adsorption, ndikupanga mgwirizano wamphamvu wa AU-S ndi gulu la sulfhydryl, zomwe zimapangitsa golide wa colloidal kuphatikizidwa ndi mamolekyu a bioactive, ndipo kafukufuku wopangidwa akhoza kukhala amagwiritsidwa ntchito pozindikira dongosolo lachilengedwe.

Immunogold ndi immunogold siliva kudetsa ntchito colloidal golide monga chikhomo angagwiritsidwe ntchito chizindikiro chimodzi kapena angapo, ndipo angagwiritsidwe ntchito pa khalidwe, kutanthauzira malo komanso kachulukidwe kafukufuku macromolecules, amene wakhala chimagwiritsidwa ntchito m'madera ambiri mankhwala ndi biology.

Guangzhou Hongwu Material Technology Co., Ltd ikupereka 99.99% kapena colloidal golide kubalalitsidwa, kukula 20nm, 100ppm-10000ppm.

Dongosolo lililonse lomwe timapanga likuwonetsa chisamaliro ndi khalidwe lomwe lakhala maziko akukula kwathu.
