Mumakore achangopfuura, iyo goridhe nanoparticles musangano weDNA wakapindirana kutsvagisa zvakanyanya kutarisisa, alkane thiol yakagadziridzwa oligonucleotides ine nanometer goridhe covalent bonding, fomu uye chinangwa polynucleotide sequence probe hybridization, inodzoreredzwa goridhe nanoparticles akaunganidzwa kuita supramolecular chimiro, kuunganidza maitiro ane tsvuku kusvika bhuruu, kuchinja kwemavara kwezvakaguma zvakabva nzira itsva colorimetry yekuona backlog DNA sequence.Iyo nzira ine high selectivity uye yakanaka senitivity, uye inogona kushandiswa mu dot hybridization, chip kuonekwa uye mamwe minda.

Iyo yekuparadzira system inoumbwa negoridhe nanoparticles mumvura inowanzozivikanwa se colloidal gold.

Zvimedu zvegoridhe zvinogona kusungwa zvakasimba neboka reamino neasina-covalent electrostatic adsorption, ichigadzira yakasimba AU-S covalent bond neboka re sulfhydryl, izvo zvinoita kuti colloidal goridhe ribatanidzwe nemamorekuru ebioactive, uye probe inoumbwa inogona kuumbwa. inoshandiswa pakuona kwebiological system.

Immunogold uye immunogold sirivheri kushatisa uchishandisa colloidal goridhe sechiratidzo inogona kushandiswa kune imwe chete kana akawanda kunyora, uye inogona kushandiswa kune yemhando, yenzvimbo uye kunyange kuwanda kwekufunda kwema macromolecules, ayo ave achishandiswa zvakanyanya mundima dzakawanda dzemishonga uye biology.

Guangzhou Hongwu Material Technology Co., Ltd iri kupa 99.99% kana colloidal goridhe dispersion, saizi 20nm, 100ppm-10000ppm.

Kurongeka kwese kwatinoita kunoratidza kutarisirwa uye kunaka kwave kuri musimboti wekukura kwedu.
